Verify the Upgrade Installation
After completing the upgrade, verify that the sever is ready for operation as follows:
Step 1.
Reconnect ac power to rear panel connectors.
Step 2.
Press the front panel power button to power on the server.
Step 3.
Wait for completion of the POST. Verify that no errors have been detected.
Step 4.
At the BCH prompt, enter the
in io
command. Verify that all installed disk drives are recognized
and operating correctly.
Step 5.
Initiate the OS and monitor operation. Check for error messages. Check the System Event Log
(SEL) for erroneous system events
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.
Follow the listed guidelines to ensure safe handling of components and to prevent harm to both you and the
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
Ensure that the system is powered off and all power sources have been
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.
Accessing the SCSI Backplane
Before adding the accessories required to convert the server from duplex to simplex, you must remove outer
components to access the SCSI backplane. To gain access to the SCSI backplane, follow these steps:
Step 1.
If rack-mounted, slide the server out from the rack until it stops. (See “Accessing a Rack-Mounted
Server” on page 177.)
