Replacing the Uplink Module
You must shut down the switch before replacing the M6PQ, M6PQ-E, or M12PQ uplink module.
Power off the switch by removing the power cables from both of the power supplies installed in the switch.
Verify that both LEDs on each power supply are off and that all of the other switch LEDs are off.
Remove the cables from each of the ports on the uplink module. Be sure to label each cable for future refernce.
Unscrew both captive screws on the front of the module.
Holding both handles on the front of the module, slide the module out of the slot.
Place the module on an antistatic surface or inside an antistatic bag. If possible, repack the module in its shipping materials for safe shipping or storage.
Remove the replacement module from its packing materials and place it on an antistatic surface.
Hold the module by its two handles and do not touch the electrical connectors on its backside. Also, to protect the electrical connectors, avoid letting them come in contact with anything other than the electrical connectors inside the chassis.
Holding the replacement module by its two handles, position the module with the electrical components on its backside facing the open uplink-module slot.
Slide the module all the way into the chassis until its front side comes in contact with the chassis. For the last 0.2 inches (0.5 cm),carefully mount the module onto the chassis connectors by pushing more firmly, but do not force the module if it does not move further (excessive force can damage the connectors).
Screw in both captive screws on the front of the module to secure the module to the chassis. Tighten each screw to 8 in-lb (0.9 N·m).
Verify that the Status (STS) LED turns on and becomes amber.
Reconnect each of the APIC-connection cables and verify that the LED for each port becomes green.
Under each set of two uplink ports, there is an Active (ACT) LED that indicates whether the ports are active for this switch. Connect cables to only the active ports.
