14 Sun Fire 880 Server Product Notes • December 2001
Correction to the Motherboard Fan Tray
Installation Procedure
The procedure “How to Install a Motherboard Fan Tray” in the Sun Fire 880 Server
Service Manual is incorrect. On systems configured with the redundant cooling fans
option, installing motherboard fan tray 5 (the primary motherboard fan tray)
requires that you disconnect the cable for motherboard fan tray 6.
The procedure should include the following steps in this order:
1. Locate the slot into which you want to install the motherboard fan tray.
a. If you are installing fan tray 5 and fan tray 6 is installed, disconnect the cable to
fan tray 6.
Note – When both motherboard fan trays are not operational in a running Sun Fire
880 system, the environmental monitoring software generates warning messages
that the fan trays are removed. If an operational fan tray is not installed quickly, the
system may initiate a thermal shutdown. During motherboard fan tray hot-plug
procedures, to avoid these messages and potential cooling issues resulting in a
system thermal shutdown, reconnect the motherboard fan tray cables for functional
fans as soon as possible.
2. Align the fan tray to be installed with its plastic guide in the chassis.
3. Slide the fan tray into the chassis.
4. If you disconnected the cable to fan tray 6 to install fan tray 5, reconnect the cable
to fan tray 6.
Continue the procedure at step 4 in the Sun Fire 880 Server Service Manual.
For more information, see “About Fan Trays” in the Sun Fire 880 Server Owner’s
Guide or the Sun Fire 880 Server Service Manual.
Correction to Disk Drive Installation Procedure
The procedure “How to Install a Disk Drive” as documented in the Sun Fire 880
Server Service Manual and the Sun Fire 880 Server Owner’s Guide is incomplete. The
following task should be included in the procedure after Step 10:
11. If you are installing more than one disk drive as part of a hot-plug procedure,
wait for the green light on the drive you just installed to light steadily (not
flashing) before installing another drive.
