Correction to the Motherboard Fan Tray Removal
Procedure
The procedure “How to Remove a Motherboard Fan Tray” in the Sun Fire 880 Server
Service Manual is incorrect. On systems configured with the redundant cooling
option, removing 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 after Step 2 in the manual, in this
order:
3. Loosen the captive screw on the fan tray you are going to remove.
4. Disconnect the fan tray cable from the fan tray you are going to remove.
5. If you are removing fan tray 5 and fan tray 6 is installed, disconnect the cable to
fan tray 6 and drape it out of the way so that you can remove fan tray 5.
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.
6. Slide the fan tray you are removing out of the system.
7. If you disconnected the cable to fan tray 6 to remove fan tray 5, reconnect the
cable to fan tray 6.
If you disconnected the cable to fan tray 6 as part of a hot-plug procedure for fan
tray 5 and you are immediately replacing fan tray 5, do not reconnect the cable to
fan tray 6 until you install fan tray 5.
