Converting SCSI From Simplex to Duplex

This section explains how to convert the HP 9000 rp4410 or rp4440 server from simplex to duplex
operation. The process involves removing a jumper, installing a duplex PCA card, and plugging
in the stowed channel B cable to the appropriate sockets.
A SCSI jumper cable bridges the two SCSI connectors on the SCSI backplane when the server is
configured for simplex operation. You must remove this jumper in order to install the duplex
board and to connect the SCSI B cable.

Safety Information

To ensure safe handling of components and to prevent harm to both you and the server, follow
these steps:
• 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!
disconnected from the server before attempting this procedure.
NOTE: Some restrictions apply to the mass storage devices that can be connected to the core
I/O SCSI HBA. If you convert the server to duplex configuration, you cannot install external SCSI
devices to the SCSI HBA core I/O controller.

Accessing the SCSI Backplane

Before adding the accessories required to convert the server from simplex to duplex, you must
remove outer components to access the SCSI backplane.
To gain access to the SCSI backplane, follow these steps:
