Installing and Starting Up the Hub 2-5

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 powerconnector 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 showwhichtestthehubisexecuting. 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).

2-6

• 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.

Youshould 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.

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

2-14

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.

Note If you are connecting the hub to a Sun workstation (or to a management

station with a female DB-25 serial connector), use a male-to-male gender changer to attach the supplied RJ-45-to-RJ-45 rollover cable and a RJ-45-to-DB-25 female DTE adapter to the management station.

Step 4 Connect the other end of the supplied rollover cable to the adapter.

Connector and cabling speciﬁcations for the console port are in the Appendix B, “Connector and Cable Speciﬁcations.”

Now that the hub is connected to a management station, you can assign IP information to the hub (see the “AssigningIP Information to the Hub (FastHub400M Models)” section on page 2-16).

Installing and Starting Up the Hub 2-15

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.

2-16

Step 2 From the terminal or PC, enter Y:

Continue with configuration dialog? [yes/no]: Y

Step 3 Enter the IP address (for example: 10.1.105.20):

Enter IP address: 10.1.105.20

Step 4 Enter the subnet mask (IP netmask) (for example: 255.255.255.0):

Enter IP netmask: 255.255.255.0

Assigning IP Information to the Hub (FastHub 400M Models)

Step 5 Enter the IP address of the default gateway (for example: 10.1.105.254):

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 ip default-gateway 10.1.105.254 ! end

Step 6 Enter Y:

Use this configuration? [yes/no]: Y

The following information is displayed:

Building configuration... 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

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 devicedoesnotsupportautonegotiation, 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:

2-18

— 10BaseT network devices—Category 3, 4, or 5 — 100BaseTX network devices—Category 5

Note Althoughyoucanuse Category 3 and 4 cablesfor10BaseTnetworks,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.

FastHub 400 10/100 Series Installation and Configuration Guide

Connecting to the 10/100 Network Ports and Uplink Port

• Connectingtodevicesthat do notautonegotiateor that havetheirspeed 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.

Step 3 Check to see that the port LED for the port that you connected in Step 1 comes

on. If the port LED does not come on, check for the following problems:

• The network device is not turned on.

• The Ethernet adapter in the network device is not operating correctly.

• You are using the wrong type of Ethernet cable.

• The Ethernet cable is damaged or not connected correctly.

Step 4 If required, reconﬁgure and reboot the connected network device. Step 5 Repeat Steps 1 through 3 for each device that you are connecting to the hub.

If you need more information about Ethernet cabling and 10/100 port pinouts, refer to Appendix B, “Connector and Cable Speciﬁcations.”

• CISCO-SIBU-MANAGERS-MIB.my contains the MIB module for management

interfaces on the FastHub 400M models.

• CISCO-SIBU-STACKABLE-DUAL-SPEED-HUB-MIB.mycontains 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 Use FTP to access the server ftp.cisco.com. Step 2 Log in with the username anonymous. Step 3 Enter your e-mail name when prompted for the password. Step 4 At the ftp> prompt, change directories to /pub/MIBs. Step 5 Use the get README command to display the readme ﬁle listing available

ﬁles.

Step 6 Use the get MIB_ﬁlename command to get a copy of the MIB ﬁle.

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 rowsarecreated 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 Group Name Description

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 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.

Alarm 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.
