Removing an EPS-LD or EPS-500 Power Supply

To remove an EPS-LD or EPS-500 power supply:
1 Disconnect the AC power by removing the plug from the wall.
2 Disconnect the AC power cord from the power supply.
3 Disconnect the redundant power cord that connects the switch to the power supply.
4 Remove the mounting screws securing the power supply to the rack.
5 Slide the power supply out of the rack.

Removing an EPS-160 Power Supply from an EPS-T

To remove an EPS-160 power supply from an EPS-T:
1 Disconnect the AC power by removing the plug from the wall.
2 Disconnect the AC power cord from the EPS-160.
3 Disconnect the redundant power cord from the EPS-160.
4 Loosen the captive retaining screws on the front of the EPS-160 and slide it out of the EPS-T.

Removing an EPS-600LS Power Module

To manually disconnect an EPS-C system or to remove the EPS-600LS modules, the recommended
practice is to disconnect the EPS-600LS modules one at a time, pausing two seconds after each
EPS-600LS disconnect. This enables a graceful power transition from the external power supplies to the
internal power supply.
To remove an EPS-600LS unit:
1 Disconnect the AC power by removing the plug from the wall.
2 Release the cable clip securing the AC power cord to the EPS-600LS unit.
3 Disconnect the AC power cord from the EPS-600LS unit.
4 Loosen the captive screws on the EPS-600LS unit securing it to the EPS-C chassis.
5 Slide the EPS-600LS unit out of the EPS-C chassis.
