Hardware Issues

This chapter describes hardware issues related to the Sun Blade X6450 server module.

Fans Run In High Speed Mode

Under some conditions, the fans run in high speed mode when the temperature conditions do not require it. This causes excess noise, power consumption, and wear on the fans.

Workaround

Upgrade to ILOM 3.0 as described in Upgrading or Migrating From ELOM To ILOM 2.0 or ILOM 3.0.

ILOM Might Report DIMM Errors Incorrectly

The ILOM provides DIMM FRU information in the web GUI, the CLI, and the IPMI interfaces.

In some cases, if you do not follow the DIMM population rules, the ILOM might report the DIMM FRU information incorrectly. For example, the DIMM FRU might be blank, or the memory location might be reported inaccurately.

Workaround

Look at the DIMM information in IPMItool.

Populate the DIMMs correctly as described in the service label and in the Sun Blade X6450 Service Manual.

Revision 2 Motherboard Supports LV FBDIMMs.

The X6450 hardware now has a second version, a new motherboard that supports LV FBDIMMs. The original version does not support these DIMMs. The version 2 motherboard is physically different, with a new 3-pin jumper. Its FRU ID is F540-7821-01. Refer to the Sun Blade X6450 Server Module Service Manual (part number 820-3539) for details.

Dongle Cable Connection

If you have a dongle cable connected to a server module, make sure to remove it before closing the door of a rack cabinet. The dongle might be damaged if it is not removed before the cabinet door is closed.

Hot-plug of the PCIe Express Module X7284A-Z Does Not Work Reliably (6687123)

Hot-plug functionality on the Sun Blade X6450 server module with the PCIe Express Module X7284A-Z does not work reliably. Do not attempt to hot-plug this Express Module.

Hot Plug X1108A-Z Does Not Work (6818703)

After plugging this board in, you must power it off, either using the power button on the board, or by powering off the chassis.

Hot Plugging PCIe EM Cards Can Cause 10 GbE Ports to be Unavailable

If you hot plug the following PCIe EM boards into a new slot, the IO ports might be unavailable. The affected boards include:

Sun StorageTek Dual 4Gb FC Dual GbE HBA(QLogic) SG-XPCIE2FCGBE-Q-Z

Sun StorageTek Dual 4Gb FC Dual GbE HBA(Emulex) SG-XPCIE2FCGBE-E-Z

1GbE Quad Port ExpressModule - Copper (Intel) X7284A-Z

InfiniBand PEM X4216A-Z and X1288A-Z

Note - This problem does not affect boards that are removed, then hotplugged into their original slot.

The following Microsoft white paper provides additional information, even though even though this issue affects Linux and Solaris operating systems as well:

Workaround

Place the board in the proper slot then power-cycle the host.
