Converting Scsi From Simplex To Duplex - HP 9000 rp4410 User's & Service Manual

Troubleshooting PCI/PCI-X Hot-Pluggable Operations
Sometimes a PCI/PCI-X card does not come online during a hot-pluggable operation due to a frequency
mismatch between the PCI/PCI-X card and the slot bus or due to other hardware errors. To determine the
type of error you are experiencing, observe the LED activity described as follows.
1. PCI/PCI-X Bus Mode or Frequency Mismatch
After you insert a PCI/PCI-X card into the slot and push the attention button, the power LED goes from
blinking to steady off and stays at steady off. The system firmware has rejected the PCI/PCI-X card and
indicates either bus-frequency or bus-mode mismatch.
After pushing the attention button, wait for the full five second operation cancellation window before
taking further action.
2. Hardware Operation Fault
If the PCI/PCI-X card cannot be powered on during a hot-pluggable addition operation, the attention LED
turns steady on and the power LED goes steady off.
3. Power draw is excessive
If the power draw for a newly installed PCI/PCI-X card is excessive (when combined with that of the
existing PCI/PCI-X expansion cards), the server powers off. If this occurs, check the power ratings of all
installed PCI/PCI-X cards. A known cause of power loss is the use of more than three PCI/PCI-X RAID
cards in the server.
If the PCI/PCI-X card cannot be powered off during a hot-pluggable removal operation, the attention
button turns steady on and the power LED remains steady on. A possible cause of this condition is that a
user application or process is using the card you are trying to remove. Determine whether the card is in
use by checking the operating system logs.
4. Slot does not power off
If the slot does not power off during a hot-plug removal operation, do not open the MRL on the OLX
divider. This action causes system failure or operating system crashes.

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. This jumper must be removed 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.
