How to Install a Motherboard Fan Tray

Note – The motherboard fan tray is also referred to as the I/O bridge fan tray by the
system's firmware and environmental software. For more information about
motherboard fan trays, see
All fan trays feature a hot-swap capability. You can remove and replace a faulty fan
tray without shutting down the operating system or turning off the system power.
For additional details, see

What to Do

1. Locate the slot into which you will 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.
The primary motherboard fan tray occupies slot 5. The fan tray numbers are
stamped into the chassis sheet metal at the base of each fan tray.
Note – When both motherboard fan trays are not operational in a running Sun Fire
V890 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-swap
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.
