Installing the HP 10/100 Hubs

If the LED display is different than what is described above especially if

the Fault LED stays on for more than 5 seconds for the Hub 12 and Hub

24, and more than 35 seconds for the Hub 12M and Hub 24M, or the Fault

LED flashes, the self test has not completed correctly. Refer to chapter 3,

“Troubleshooting” for diagnostic help.

3. Mount the Hub

After you have verified that the hub passes self test, it is ready to be mounted

in the location you have prepared. The hub can be mounted in these ways:

■ in a rack or cabinet

■ on a wall

■ on a horizontal surface

Rack or Cabinet Mounting

The HP 10/100 hubs are designed to be mounted in any EIA-standard 19-inch

telco rack or in an equipment cabinet such as a server cabinet.

Caution For safe operation, please read the mounting precautions in

the section, “Installation Precautions” earlier in this chapter before

mounting a hub.

1. Use a #1 Phillips (cross-head) screwdriver and attach the mounting

brackets to the hub with the included 8-mm M4 screws.
