Pci Or Pci-X Hot Plug; Memory - HP 1850R - ProLiant - 128 MB RAM Troubleshooting Manual

To check for failure if your server has redundant PPMs, briefly remove the
appropriate access panel to inspect for the following:
•
If the failure LED is lit, then one of the voltage regulators on the redundant PPM
has failed. The PPM is no longer redundant. The system will continue to run
without redundancy, displaying a message from the Health Driver (if loaded on
the system) to notify the user of the loss of redundancy.
•
If a PPM fails, the server is forced into a reset condition and may not power up.
In either case, replace the PPM.

PCI or PCI-X Hot Plug

Some servers support PCI or PCI-X Hot Plug functionality, which provides the
ability to remove, replace, upgrade, and add PCI or PCI-X expansion boards without
the server being powered down. PCI or PCI-X Hot Plug device drivers and operating
system support are required to enable this functionality. If you are having problems
with PCI or PCI-X Hot Plug functionality, be sure that the proper drivers and support
exist on your server and that you are following the requirements described in your
server-specific user documentation for this technology.
If errors are occurring, be sure that you are removing power to the slot using the PCI
Hot Plug Utility (if supported by your server) or the PCI Hot Plug button before
adding or removing any PCI hot plug devices.

Memory

Use Table 2-6 to troubleshoot memory problems. Be sure that the memory meets
your server requirements and that it is installed as required by your server. Some
requirements may include that memory banks cannot be partially populated, or that
all memory within a memory bank must be the same size, type, and speed. Refer to
your server-specific user documentation to determine if the memory is installed
correctly.
