Installing the Gaskets

Gasket rework is needed when a customer has an HP Netserver LXr 8500 with a slower processor speed than 900

MHz and wishes to upgrade to 900 MHz. When the LXr 8500 processor is upgraded to 900 MHz, the gaskets for the

chassis assembly and the PCI Hot plug cover must be replaced in order that it meets EMI standards.

The gaskets are

included in the 900 MHz CPU Upgrade Kit.

When a new LXr 8500 is purchased, this step is unnecessary as all LXr

8500s have been upgraded at the factories to meet the EMI standards for 900 MHz processors.

CAUTION

Do not operate the HP Netserver LXr 8500 with its top cover removed.

Serious damage to the HP

Netserver could result.

To install the new gaskets, complete the following procedure:

1.

If the HP Netserver is operating, log off all users and, if necessary, back-up files.

Power down the HP

Netserver. Refer to the

HP Netserver LXr 8500 Installation Guide,

Chapter 3, “Opening and Closing the HP

Netserver.”

NOTE

The power supplies will continue to provide standby current to the HP Netserver until the power

cord is disconnected.

WARNING

Always disconnect the power cord before removing the top cover to avoid exposure to high

energy levels that may cause burns when parts are short-circuited by metal objects such as tools or

jewelry. Disconnect any telephone cables to avoid exposure to shock hazard from telephone

ringing voltages.

2.

Pull the HP Netserver out from the rack on its slides.

3.

Remove the two T-15 Torx

®

screws on the top cover, near the front of the chassis.
