Installing Additional Components and Configuring

Converting SCSI From Simplex to Duplex

This section explains how to convert your hp Integrity rx4640 Server from simplex to duplex operation. The process involves

removing a jumper cable, installing a duplex PCA card, and plugging in the stowed channel B cable to the appropriate sockets.

NOTE In simplex mode, you may remove the cover from channel B for connection of external SCSI devices.

The Windows operating system only supports duplex operation.

Safety Information

Follow the procedures listed below to ensure safe handling of components and to prevent harm to both you and the HP Server:

• Use an antistatic wrist strap and a grounding mat, such as those included in the Electrically Conductive Field Service

Grounding Kit (HP 9300-1155).

• Handle accessory boards and components by the edges only. Do not touch any metal-edge connectors or any electrical

components on accessory boards.

• Do not wear clothing subject to static charge build-up, such as wool or synthetic materials.

WARNING Hazardous voltages are present inside the HP Server. Always remove AC power from the server

and associated assemblies while working inside the unit. Serious injury may result if this warning is

not observed.

CAUTION Some restrictions apply to the mass storage devices that may be connected to your core I/O SCSI HBA. See

“Core I/O Connections” on page 71. If you convert your system to duplex configuration, you may not install

external SCSI devices to the SCSI HBA core I/O controller.

Accessing the SCSI Backplane Board

Prior to adding the accessories required to convert your hp Integrity rx4640 Server from simplex to duplex you must remove

outer components to access the SCSI backplane board. To gain access to the SCSI backplane board perform the following

steps:

Step 1. If rack mounted, slide the HP Server out from the rack until it stops. See “Accessing a Rack Mounted Server” on

page 141.

NOTE If your HP Server is pedestal mounted, you need not remove the pedestal to perform the simplex

to duplex conversion. Proceed directly to the next step.

Step 2. Remove the front bezel. See “Front Bezel” on page 144.

Step 3. Remove the front cover. See “Removing the Front Cover” on page 145.

Step 4. Remove the memory extender board. See “Memory Extender Board” on page 151.

Step 5. Remove the processor extender board. See “Memory Extender Board” on page 151.
