Replacing the controller power supply

This section describes the procedure for replacing the power supply used in EVA 4000/6000/8000

products.

NOTE:

Because this component is used in several products, the drawings may reﬂect a different enclosure than

Before you begin

Observe the following precautions when replacing a power supply.

CAUTION:

Removing a power supply signiﬁcantly changes the air ﬂow within the enclosure . Both power supplies

must be installed for the enclosure to cool properly. If a power supply fails, leave it in place in the

enclosure until a new power supply is available to install.

If cabling is obstructing access to the p ower supply, carefully move the cables out of the way to avoid

loosening any connections.

Parts can be damaged by electrostatic discharge. Use proper anti-static protection. Refer to the

documentation that shipped with your system for additional information.

Have a copy of the product User Guide available for reference. You can download a copy of the User

Guide from the product support page on the HP web site.

Verifying component failure

Before replacing a power supply, use the following methods to verify the component failure.

CAUTION:

If Command View EVA does not present a status consistent with that of the power supply status indicator,

or if Command View or the System Event Analyzer indicates multiple hardware failures, contact HP

support for assistance. The HP support web site is located at h

ttp://www.hp.com/support

• Analyz e any failure messages you may have received from sys tem monitoring (System Event

Analyzer).

• Check status using Command View EVA:

CAUTION:

If you are running HP StorageWorks Command View EVA 4.0, the power supply numbering

presented in the management interface is inconsistent with the numbering used in the storage system

and reported by the ISEE/WEBES monitoring tool. HP Command View EVA 4.0 identiﬁes the left

power supply as 1 and the right power supply as 2. The correct numbering should be 0 and 1

respectively. Remember to make this conversion when replacing a power supply. This inconsistency is

corrected in later versions of HP Command View EVA.
