Converting SCSI From Duplex to Simplex Operation

This section explains how to convert your SCSI from duplex to simplex. The procedure requires
unplugging and stowing the SCSI B cable, removing the SCSI duplex board, and installing a
jumper cable on the SCSI backplane.

Safety Information

Use care to prevent injury and equipment damage when performing removal and replacement
procedures. Voltages might be present within the server. Many assemblies are sensitive to damage
by electrostatic discharge.
To prevent harm to both you and the server,follow the listed guidelines to ensure safe handling
of components:
• 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 converting your server.
Voltages are present at various locations within the server whenever an ac power source is
connected. This voltage is present even when the main power switch is in the off position.
Failure to observe this warning can result in personal injury or damage to equipment.
