4-6 Accessing the Backplane Tray
The SC946ED includes three primary backplanes and a mid-plane which are con-
tained in a tray that is accessed from the front of the chassis. It is highly unlikely
that it will become necessary to access the backplane tray. In the unlikely event
that the Supermictro Technical Support Team directs you to check the connections
to the backplanes and midplane or to install a new backplane tray, this section
covers instructions for opening the backplane tray. Replacement backplane trays
are availble from Supermicro. For additional information, see Appendices B and C
of this
Opening the Backplane Tray
1. Unplug the power cords from the rear of the power supplies and remove the
power supplies as directed in Section 4-9.
2. Remove the power supply cage by removing the screws securing it to the
chassis.
3. Remove the power distributor board as described on page 4-10.
4. Disconnect the front panel cable connector.
5. Disconnect the 8-pin power connector from the front panel of the chassis,
