Chapter 5 Installation and Configuration

Install Additional Memory

For the HP NetRAID-3Si adapter, cache memory resides in a 16-MB battery-

backed 60-ns EDO (Extended Data Output) DRAM SIMM. You can upgrade the

cache memory to 64-MB, using the D7132A SIMM Upgrade for

HP NetRAID-3Si.

To upgrade cache memory:

1. Verify that the Battery Backup Unit is not plugged in on the

HP NetRAID-3Si adapter.

2. Install the new SIMM according to the instructions supplied with the

additional memory.

Connect Battery Backup Unit

NOTE The HP NetRAID-1Si adapter does not have a Battery Backup

Unit.

The HP NetRAID-3Si adapters are shipped with the Battery Backup Unit for the

cache memory. The Battery Backup Unit is installed and charged, but

disconnected. Follow the directions below to connect the Battery Backup Unit

before you install the adapter.

CAUTION When the Battery Backup Unit is connected:

• Do not place the HP NetRAID-3Si adapter on a

conductive surface.

• When installing the adapter, do not allow the adapter or

its Battery Backup Unit to touch any part of the

HP NetServer. Doing so could short the battery, and it

may damage other components. You may place the

adapter on an antistatic mat.
