Media Converter or Switch Module

If the PR LED on the module is OFF, do the following:

❑ Check that the module is securely seated in the chassis.

❑ Check that the chassis is receiving power.

❑ Try installing the module in another expansion slot.

If a LK LED on the module is OFF, do the following:

❑ Check that the end-node connected to the port is ON.

❑ Check to be sure that the cable is securely connected to the ports

on the module and on the end-node.

❑ Check to be sure that the appropriate type of cable for the port is

being used.

❑ For the fiber optic port, check that the maximum allowable loss

budget has not been exceeded.

If the LK LED is green but there is a communication problem between

the end-nodes connected to the module (and you are not running a link

test), check the following:

❑ For a media converter module, check to be sure that the end-

nodes connected to the ports are operating at the same speed

and at a speed appropriate for the PowerBlade model.

❑ For a media converter module, check that the end-nodes are

operating in the same duplex mode.

❑ For a media converter module, check that the Link

Test/MissingLink button is in the M/L ON (IN) position.

❑ Check that the maximum allowable loss budget for the fiber optic

cable has not been exceeded.

❑ For a switch module, check to be sure that the DIP switches are set

correctly.
