Problem

The network

connection is not

working properly.

Try the following procedures:

• For the indicated port, verify that both ends of the cabling, at the switch and

the connected device, are securely connected.

• 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 connections, in general, for connecting to an end node (MDI

port), use "straight- through" cable; for connecting to MDI-X ports on hubs

or other switches, use "crossover" cable.

Note: For the 10/100-TX GL Module and the 100/1000-T GL Module in the

default configuration (Auto), the modules automatically negotiate

whether each port operates as MDI or MDI-X, depending on the cable

type and the connected device's operation, and either a straight-

through or crossover cable can be used. If the module configuration is

changed to one of the fixed configuration options though (for example,

100-Full Duplex), then the port operates as MDI-X only and the above

statement about straight-through and crossover cables applies.

– for fiber-optic connections, verify that the transmit port on the switch is

connected to the receive port on the connected device, and the switch

receive port is connected to the transmit port on the connected device.

• For a 1000 Mbps connection, verify that the network cabling complies with the

IEEE 802.3ab standard. The cable should be installed according to the ANSI/

TIA/EIA-568-A-5 specifications. Cable testing should comply with the stated

limitations for Attenuation, Near-End Crosstalk, Far-End Crosstalk, Equal-Level

Far-End Crosstalk (ELFEXT), Multiple Disturber ELFEXT, and Return Loss.

The cable verification must include all patch cables from any end devices,

including the switch, to any patch panels in the cabling path.

• Verify that the port has not been disabled through a switch configuration

change.

You can use the console interface, or, if you have configured an IP address

on the switch, use the web browser interface, or HP TopTools for Hubs &

Switches network management software to determine the state of the port

and re-enable the port if necessary.

• If the other procedures don't resolve the problem, try using a different port or

a different cable.
