Installation Steps
Installing the Switch 208/224
If the Port LED does not go on when the network cable is connected to the
port, use this table to solve the problem:
Condition Diagnostic Tip
Port LED is still off when
a cable is
connected
Try the following:
• For the indicated port, verify that both ends of the cabling,
switch and connected device, are snug.
• Verify the connected device and switch are both powered
on and operating correctly.
• Verify that you have used the correct cable type for the
connection. For twisted-pair cable connections, in gener-
al, for connecting to an end node, use “straight-through”
cable; for connecting to hubs or other switches, use
“crossover” cable.
• Verify that you have not connected a 10 Mbit/s network
cable into one of the 100 Mbit/s ports.
• Verify that if you are connecting the cable to port 1, the
switch does not have an optional expansion module in-
stalled in the expansion slot in the back of the switch.
When an expansion module is installed, it uses the port 1
circuitry to communicate with the rest of the network
through the switch and the port 1 RJ-45 connector is thus
disabled.
• Use a different port or a different cable.
If you have installed the Switch Management Module, you can use
the console interface or HP AdvanceStack Assistant network
management software to determine the state of the port and re-
enable the port if necessary.
