network device is powered on and operating correctly.

 

 

 

 

Verify that the transmit port on the Dell device is

 

 

 

 

connected to the receive port on the other network device,

 

 

 

 

and that the receive port on the Dell device is connected

 

 

 

 

to the transmit port on the other network device. If you are

 

 

 

 

not certain, remove the two cable connectors from the

 

 

 

 

port connector and reinsert them in the port connector,

 

 

 

 

reversing their order.

 

 

 

 

Dust may have accumulated in the cable connector or port

 

 

 

 

connector. For information about cleaning the connectors,

 

 

 

 

refer to “Cleaning the fiber optic connectors” on page 43.

 

 

 

 

Verify that the port has not been disabled through a

 

 

 

 

configuration change.

 

 

 

 

Check that the configuration has not forced the use of the

 

 

 

 

RJ45 port shared with the SFP port.

 

 

 

 

If the other actions don’t resolve the problem, try using a

If a problem persists after taking these actions, contact Dell Technical Support.

Tracing a route

To determine the path through which a Dell device can reach another device, enter a command similar to the following at any level of the CLI on the device.

PowerConnect> traceroute 192.33.4.7

Syntax: traceroute <host-ip-addr> [maxttl <value>] [minttl <value>] [numeric] [timeout <value>] [source-ip <ip addr>]

The CLI displays trace route information for each hop as soon as the information is received. Traceroute requests display all responses to a given TTL. In addition, if there are multiple equal-cost routes to the destination, the Dell device displays up to two responses by default.

Troubleshooting network connections

For the indicated port, verify that both ends of the cabling (at the device and the connected device) are snug.

Verify that the device and the connected device are both powered on and operating correctly.
