Powering Up the Hub and Running POST  
Powering Up the Hub and Running POST  
Before installing and cabling the hub, you might want power up the hub and verify that it  
is operational.  
To power up the hub, connect one end of the AC power cord to the AC power connector on  
the hub and the other end of the cord to a power outlet. If your configuration has a Cisco  
RPS, see the RPS documentation.  
The hub begins the power-on self-test (POST) after power up. POST consists of the  
ten individual tests listed in Table 4-2. The port LEDs show which test the hub is executing.  
At power up, all port LEDs are green. As each POST test executes, a port LED turns off.  
For example, if the LED for port 12x is off, the boot code test (test 1) is being executed. On  
the hub, the port LED for port 12x turns off first, followed by ports 11x, 10x, 9x, and so on.  
The LEDs for ports 1x and 2x are not used during POST. The SYSTEM LED is blinking  
green while POST is executing.  
When POST completes, the following conditions can exist (if other devices are not  
connected to the hub):  
All POST tests passed—If the SYSTEM LED is green and all of the port LEDs are off,  
no problems were detected. The hub is fully operational.  
Nonfatal failure(s) detected—If the SYSTEM LED is amber and the hub is functional,  
POST detected one or more nonfatal failures. Although the hub is still operational and  
can forward packets, it might not operate optimally. Refer to the POST failure message  
displayed on the diagnostic console screen, identifying the nonfatal failure(s) detected  
(see the “Understanding POST Results” section on page 4-4).  
Fatal failure(s) detected—POST completes all tests, even after detecting a fatal failure.  
If the SYSTEM LED is amber and one or more of the port LEDs are amber, POST  
detected one or more fatal failures. The hub is not operational, but the amber port  
LED(s) indicate which test(s) failed.  
You should inform your system administrator if one or more nonfatal failures are detected.  
Contact your Cisco representative or reseller for support if any fatal failures are detected.  
The “Understanding POST Results” section on page 4-4 provides additional information,  
including the possible causes of nonfatal and fatal failures.

Installing the Hub in a Rack  
This section describes how to install the hub in 19- and 24-inch standard and telco racks.  
Note Be sure the hub is powered off and is not connected to a power source before you  
perform the steps in the sections that follow.  
Attaching the Brackets to the Hub  
The bracket orientation and the screws you use depend on whether you plan to use a 19-inch  
or a 24-inch rack:  
For a 19-inch rack-mount, use the Phillips flat-head screws to attach the long side of the  
bracket to the hub.  
For a 24-inch rack-mount, use the Phillips truss-head screws to attach the short side of  
the bracket to the hub.  
Place the hub on a level surface, and use two of the supplied Phillips flat-head or truss-head  
screws to attach a mounting bracket to each side of the hub.  
Figure 2-1, Figure 2-2, and Figure 2-3 show how to attach one bracket to one side of the

Installing the Hub on a Wall  
This section describes how to attach the hub in parallel and vertically to a wall.  
Note Be sure the hub is powered off and is not connected to a power source before you  
perform the steps in the sections that follow.  
Attaching the Brackets to the Hub  
The bracket orientation depends on whether you plan to parallel or vertical wall-mount the  
hub:  
For a parallel wall-mount, use the Phillips truss-head screws to attach the short side of  
the bracket to the hub.  
For a vertical wall-mount, use the Phillips flat-head screws to attach the long side of the  
bracket to the hub.  
Place the hub on a level surface, and use two of the Phillips truss-head or flat-head screws  
to attach a mounting bracket to each side of the hub.

Connecting to the Console Port (FastHub 400M Models)  
Connecting to the Console Port (FastHub 400M Models)  
To connect the RJ-45 console port of a FastHub 400M model to a management station or  
modem, you must use the supplied RJ-45-to-RJ-45 rollover console cable and the  
appropriate adapter and follow these steps.  
Note The rollover console cable and a RJ-45-to-DB-9 female DTE adapter are supplied  
with the hub. If your management station requires a different adapter—such as a  
RJ-45-to-DB-25 female DTE or RJ-45-to-DB-25 male DCE adapter—you must provide it.  
Step 1  
Configure the hub console port settings to match the management station or  
modem. These are the default settings of the console port:  
9600 baud  
8 data bits  
1 stop bit  
No parity  
No flow control  
You can change the console port characteristics of the hub from the web-based  
System Configuration Page (see the “Changing the System Configuration”  
section on page 3-40) or by using the terminal command from the CLI.  
Note Make sure the settings of the console port and the management station or  
the modem match.

Assigning IP Information to the Hub (FastHub 400M Models)  
Assigning IP Information to the Hub (FastHub 400M  
Models)  
After you install the hub and connect it to a management station, you can assign IP  
information to the hub. IP information identifies the hub to the network and is required to  
manage and monitor the hub through the FastHub 400 series Hub Manager, the CLI, or  
SNMP.  
You can assign IP information to the hub by following the hub start-up prompts displayed  
from a terminal emulation program on your management station.  
You should contact your system administrator for the following information:  
Hub IP address  
Subnet mask (netmask)  
Default gateway (router)  
To assign IP information to the hub, follow these steps:  
Step 1  
From your management station, start the terminal emulation program.  
After POST completes, the Continue with configuration dialog? prompt appears  
on the management station, and you can then follow the prompts to assign IP  
information to the hub.  
Step 2  
Step 3  
Step 4  
From the terminal or PC, enter Y:  
Continue with configuration dialog? [yes/no]: Y  
Enter the IP address (for example: 10.1.105.20):  
Enter IP address: 10.1.105.20  
Enter the subnet mask (IP netmask) (for example: 255.255.255.0):  
Enter IP netmask: 255.255.255.0

Enter IP default gateway: 10.1.105.254  
Note If the management station from which the FastHub 400 series Hub  
Manager is used is not on the same IP subnet as the hub, you must also assign a  
default gateway (the router for the local subnet).  
The following information is displayed:  
The following configuration command script was created:  
ip address 10.1.105.20 255.255.255.0

Use the enabled mode ‘configuration’ command to modify this  
configuration.  
Press RETURN to get started.  
Pressing Return opens a CLI session.  
Step 7  
Exit from the terminal session.  
You can now use the hub with its default values or configure and monitor it by using the  
FastHub 400 series Hub Manager, the CLI, or SNMP and the MIB files.  
Installing and Starting Up the Hub 2-17  
 
Connecting to the 10/100 Network Ports and Uplink Port  
Connecting to the 10/100 Network Ports and Uplink Port  
You can connect the 10/100 network ports and the uplink port to the ports on any 10BaseT  
or 100BaseTX network device, such as workstations, servers, switches, routers, and other  
hubs.  
The 10/100 network ports (ports 1x through 12x or 1x through 24x) are internally crossed.  
These ports require a crossover cable to connect to another hub or switch (unless you are  
connecting to the uplink port on another FastHub or device). When connecting to a  
workstation, server, or router, these ports require a straight-through cable.  
The 10/100 uplink port (port 12 or 24) is not internally crossed and requires a  
straight-through cable to connect to a server, hub, switch, or router.  
By default, each 10/100 port on the hub configures itself to operate at the speed of the port  
to which it is connected. If the port on the attached device does not support autonegotiation,  
you can explicitly set the 10/100 port to match the speed of the attached port by using one  
of the management interfaces available to the FastHub 400M models.  
When connecting other network devices to the 10/100 ports, keep the following guidelines  
in mind:  
Use the following types of twisted-pair cables when connecting the 10/100 network  
ports or the 10/100 uplink port to a network device:  
10BaseT network devices—Category 3, 4, or 5  
100BaseTX network devices—Category 5  
Note Although you can use Category 3 and 4 cables for 10BaseT networks, these cable  
types will not work for 100BaseTX network devices. When designing a network that  
includes autosensing repeaters like the FastHub 400 models, keep in mind that  
100BaseTX traffic cannot be sent over these cable types.  
Use a straight-through cable to connect two ports when one of the ports is designated  
with an X. Use a crossover cable to connect two ports when both ports are designated  
with an X.  
2-18  
FastHub 400 10/100 Series Installation and Configuration Guide  
 
Connecting to the 10/100 Network Ports and Uplink Port  
Connecting to devices that do not autonegotiate or that have their speed setting manually  
set can reduce performance or result in no link. To maximize performance, choose one  
of these methods for configuring the 10/100 ports:  
Let both ports autonegotiate port speed.  
Manually set the same speed setting for the ports on both ends of the connection.  
When a 10/100 device connected to the hub changes speeds (from 10 to 100 Mbps or  
from 100 to 10 Mbps), the device must reboot. The device then drops the link to the hub  
and recreates the link after rebooting. (If the device does not reboot after changing  
speeds, the hub does not detect the change in speed.)  
Caution If you connect to ports 12x and 12 (or ports 24x and 24), you will disable both  
ports.  
Follow these steps to connect to 10BaseT or 100BaseTX devices:  
Step 1  
Connect one end of the Ethernet cable to a 10/100 port on the hub, as shown in  
Figure 2-9.  
Note When connecting the hub to workstations, servers, and routers, ensure  
that the cable is a straight-through, twisted-pair cable. When connecting the hub  
to switches or repeaters, use a crossover cable.

After you assign IP information to the hub, you can access the hub management interfaces.  
This section provides information for accessing the FastHub 400 series Hub Manager, the  
CLI, and SNMP and MIB files.  
2-20  
FastHub 400 10/100 Series Installation and Configuration Guide  
 
Accessing the FastHub 400 Series Hub Manager  
Accessing the FastHub 400 Series Hub Manager  
To access the hub manager, all you need is the IP information of the hub (and the password  
if one has been assigned). IP information for the hub is usually assigned when the hub is  
first started up after installation. (See the “Assigning IP Information to the Hub (FastHub  
400M Models)” section on page 2-16.)  
Note You can access the hub manager from a PC connected to one of the 10/100 ports.  
Therefore, make sure that you do not disable or otherwise misconfigure the port through  
which you are communicating with the hub. You might want to write down the port number  
to which you are connected. Make changes to the hub IP information with care.  
To access the hub manager, follow these steps:  
Step 1  
Start Netscape Communicator (4.03 or higher) or Microsoft Internet Explorer  
(4.01 or higher).  
Step 2  
Ensure that the following browser features are enabled:  
Java  
JavaScript  
Set the caching of pages to Every time in Communicator or  
Every visit to the page in Internet Explorer.  
Step 3

Enter the password. The hostname> prompt is displayed after you enter the correct  
password.  
For complete information about the CLI, refer to the FastHub 400 10/100 Series Command  
Reference.  
Accessing the MIB Files through SNMP  
You can access the hub MIB files through SNMP. The following MIB files contain variables  
that can be set or read to provide information about the hub and the traps generated by the  
hub.  
RFC1213-MIB.my contains the MIB II (RFC 1213).  
ETHERLIKE-MIB.my contains the Ethernet Transmission MIB (RFC 1643).  
CISCO-CDP-MIB.my contains the CDP MIB.  
SNMP-REPEATER-MIB.my contains the standard MIB for managing the hub.  
RMON-MIB.my contains the RFC 1757 RMON (Groups 1, 2, 3, and 9). More  
information about RMON and the RMON groups is provided in the “Remote  
Monitoring” section on page 2-25.  
CISCO-SIBU-SIMPLE-UPGRADE-MIB.my contains the MIB module for upgrading  
the firmware on Cisco low-end devices.  
Installing and Starting Up the Hub 2-23  
 
Accessing the Management Interfaces (FastHub 400M Models)  
CISCO-SIBU-MANAGERS-MIB.my contains the MIB module for management  
interfaces on the FastHub 400M models.  
CISCO-SIBU-STACKABLE-DUAL-SPEED-HUB-MIB.my contains the MIB module  
that extends the REPEATER-MIB to manage Cisco low-end stackable repeater  
products.  
If you are going to manage the hub by using SNMP and the MIB files, the Read and Write  
community strings need to be set. To do this, you can either  
Use the default community strings  
Read community string. The default is public.  
Write community string. The default is private.  
Assign community strings by using the SNMP Management Page or by using the  
snmp-server community command on the CLI.  
Note Wait approximately 30 seconds for the changes to be saved to permanent storage  
before turning off the hub, or the changes might not be saved.  
You can obtain a copy of the MIB files in the following ways:  
Using File Transfer Protocol (FTP) to access the ftp.cisco.com server.  
Using Cisco Connection Online (CCO) to access the cisco.com server.  
Using FTP to Access the MIB Files  
To obtain a MIB file, follow these steps:  
Step 1  
Step 2  
Step 3  
Step 4  
Step 5  
Use FTP to access the server ftp.cisco.com.  
Log in with the username anonymous.  
Enter your e-mail name when prompted for the password.  
At the ftp> prompt, change directories to /pub/MIBs.  
Use the get README command to display the readme file listing available  
files.

Accessing the MIB Files through SNMP  
Using CCO to Access the MIB Files  
To access the MIB files from CCO, click Software & Support to display the Software  
Center site.  
CCO serves a wide variety of users through two interfaces that are updated and enhanced  
simultaneously: a character-based version and a multimedia version that resides on the  
World Wide Web (WWW). The character-based CCO supports Zmodem, Kermit,  
Xmodem, FTP, and Internet e-mail, and it is excellent for quick access to information over  
lower bandwidths. The WWW version of CCO provides richly formatted documents with  
photographs, figures, graphics, and video, as well as hyperlinks to related information.  
You can access CCO in the following ways:  
Telnet: cco.cisco.com  
Modem: From North America, 408 526-8070; from Europe, 33 1 64 46 40 82. Use the  
following terminal settings: VT100 emulation; data bits: 8; parity: none; stop bits: 1;  
and connection rates up to 28.8 kbps.

additional information, contact [email protected].  
Remote Monitoring  
The Remote Monitoring (RMON) MIB is used by network managers to monitor remote  
devices. An RMON implementation consists of a software probe that continually collects  
statistics about a LAN and a management station that communicates with the probe. The  
probe transfers information to the management station on request or when a predefined  
threshold is crossed.  
The hub supports four RMON groups (Table 2-1) as defined in RFC 1757. Default statistic  
rows are created for each port when you start the hub. You can obtain information about the  
four supported groups by using any SNMP management application.

Table 2-1  
RMON Groups and Their Functions  
Description  
Group Name  
Statistics  
This group collects traffic and error statistics for a specific interface. For  
example, you could use this group to determine how many error packets have  
been seen on a given port.  
Statistics from this group can be used by the history group to record historical  
views of network performance. A statistics row is established by default for  
each hub port.  
History  
Alarm  
This group periodically samples the counters generated by the statistics  
group. This information can be used to establish baseline information  
regarding network activity. You can define the intervals you want to record  
information for, and you can define how many of the samples are to be stored.  
Note RMON statistics gathering has a maximum limit of 50 history buckets  
per historyControlTable entry.  
This group generates alarms according to user-defined thresholds. You could,  
for example, configure RMON to generate an alarm when alignment errors on  
a port exceeded a predefined limit. Rising and falling thresholds can be  
defined, and the events group can generate traps and automated responses  
based on the alarms.  
Event  
This group sends traps to the management station based on information  
(alarms) received from the alarm group.  
Where to Go Next  
Now that you have installed the hub and, if you have a FastHub 400M models, assigned IP  
information to the hub, you can continue to  
Chapter 3, “Configuring and Monitoring from the Hub Manager” for configuration and  
monitoring information. (FastHub 400M models only).  
Appendix C, “FastHub Stacks” for interconnecting the hub to other FastHub 400M  
models to form hub stacks.  
Appendix D, “Switched Uplink Modules” for descriptions of the optional switched  
uplink modules and procedures for installing and connecting to them.
