working on this hot-swap unit.

Removing an Ethernet Switch Blade

CAUTION Possible data loss or network damage. Before removing an Ethernet Switch Blade, ensure that

your VLAN topology will allow this Switch Blade to be removed without causing data loss or

damage to the network.

CAUTION Electrostatic Discharge Hazard. Observe all ESD safety precautions while completing this

procedure. Failure to follow ESD safety precautions could result in damage to the 14-Slot Shelf

and equipment.

To remove an Ethernet Switch Blade, complete the following steps:

Step 1. At the front of the 14-Slot Shelf blade cage, loosen the two retaining screws that secure the

Ethernet Switch Blade front panel to the blade cage.

Step 2. Simultaneously pull both Ethernet Switch Blade extraction levers to the one-half open (extract)
