1. Lower the cover so that the pins at the rear of the cover slide down into the
slots at the rear of the system-board tray. Before you close the cover, make
sure that all components are installed and seated correctly, all internal cables
are correctly routed, and you have not left loose tools or parts inside the
system-board tray.
2. Pivot the cover to the closed position until it clicks into place.
3. Install the system-board tray in the chassis (see “Installing the system-board
tray in a 2U chassis” on page 127 or “Installing the system-board tray in a 3U
chassis” on page 129).
Removing the system-board tray from a 2U chassis
To remove the system-board tray from a 2U chassis, complete the following steps.
If the server contains an expansion enclosure, you remove the expansion enclosure
and the system-board tray from the chassis as one assembly.
Attention: When two system-board trays are installed in the chassis, do not
operate the upper system-board tray with the lower system-board tray removed or
powered off, except for servicing. When the lower system-board tray is removed or
powered-off, chassis-level systems-management information is not available. For
example, chassis fan speeds and temperatures might be returned as zero values.
In this situation, the chassis continues to operate normally, because the power
supply and fans are designed to operate independently.
