Top Cover
The server top cover helps the cooling subsystem maintain pressure areas within the server.
The top cover also protects against damage to internal components and accidental exposure to
hazardous voltages. For these reasons, the server top cover is includes an interlock switch to
server power.
The interlock switch has two components. One component is mounted inside the server on
the housing for power supply, PS1, and includes a wire that plugs into the motherboard. The
other component is mounted on the underside of the top cover. When the cover is installed these
two components align, closing the switch and allowing power to the server. When the cover is
removed, the switch opens removing power from the server. If the cover is removed while the
server is powered on to full power mode, power to the server is
immediately
switched off.
Action
: If the server does not power on, check that switch is intact and properly aligned. Ensure
that the server top cover is in place and sits flat and snug on top of the server. Ensure that the
interlock switch components have not been damaged, removed, or misaligned.
Prevention
: After removing the top cover, take care that the cover does not get bent, or that
the component on the underside is not damaged. When servicing the server, take care that the
internally mounted interlock switch component does not get damaged or misaligned. Never
operate the server without the top cover installed.
