General Board And Feature Issues - Sun Microsystems Sun Fire V60x Manual

Verify that all chassis and power supply fans are properly installed and
■
functioning.
Approved heat sinks must be properly installed on the processors. Do not attempt
■
to run the processors without a heat sink for even a few moments.
If the system is running slowly or you receive a processor error message, enter
■
BIOS setup and enable processor retest. This test will be run only on the next
reboot and will retest the processors and bring them back online if marked failed.
When using multiple PCI adapter cards in a PCI riser with more than one slot,
■
populate the slots from the bottom up.

General Board and Feature Issues

1. Why is the serial COM2 port implemented through an RJ-45 connector?
The server board is designed specifically for the High Density Rack Mount
(HDRM) environment. Therefore, several HDRM features, such as a high density
serial port have been implemented. The intention for the rear RJ-45 serial port is
for serial concentrator applications. Several serial concentrators on the market are
accessed through an RJ-45 serial port. In order to accommodate both serial
concentrator communication standards and standard modem/UPS type
communication standards, there are a set of jumpers located directly behind the
RJ-45 serial connector on the baseboard. These jumpers can be used to route the
DSR signal to pin 7 on the connector for serial concentrator type implementations
or have the DCD signal routed to that pin for modem/UPS type implementations.
See "Setting the Serial COM2 Port Jumper" on page 4-4 for details.
2. How do I disable the integrated components?
Onboard controllers can be disabled through the server board BIOS setup. To
enter BIOS setup, press F2 when prompted during the boot up process.
3. What jumpers are available and how should they be set?
There are three headers on the main jumper block on the server board at the left
edge of the board. Jumpers at this location are available for the following
functions:

An additional jumper is available for BMC Write Protect (WP). It is located
towards the rear of the main board, at the left side of the full-depth PCI slot.
For normal operation, these jumpers should be left in their default position as
shipped from the factory.
