Removing a Power Module Assembly

To remove the power module assembly:

1. Notify the customer the director will be powered off. Ensure the customer’s

system administrator quiesces Fibre Channel frame traffic through the

director and sets attached devices offline.

2. If the director is installed in a stand-alone configuration, go to step 3. If the

director is rack-mounted, unlock and open the cabinet front and rear doors as

directed by the customer representative.

3. Power off and unplug the director (“Power-Off Procedure” on page 201).

WARNING: Ensure both power cords are disconnected from the power

module assembly prior to removal or replacement.

4. Follow ESD procedures by attaching a wrist strap to an approved bench

grounding point and your wrist.

Caution: To avoid causing machine errors or damage while working on the

director, follow ESD procedures by connecting a grounding cable to an

approved bench grounding point and wearing an ESD wrist strap.

5. Unseat and disconnect (but do not remove) both power supplies (“RRP:

Redundant Power Supply” on page 245).

6. Remove the RFI shield.
