Installing A New Fan; Replacing The Module System Controller - Silicon Graphics Origin200 Owner's Manual

Installing a New Fan

Follow these steps to install a fan:
1. Lower the new fan into the system.
2. Snap a plastic rivet in the top corners of the fan to secure it to the sheet metal.
The rivet has two parts: a sleeve and a pin.
Place the pin part-way inside the sleeve, then slide both through the hole in the
fan.
Press the pin and sleeve together towards the sheet metal. The pin and sleeve
will slide into place with the ends of both protruding through the sheet metal.
If you have large hands or fingers, you may find it easier to handle the rivets
with needlenose pliers or large tweezers.

Replacing the Module System Controller

For this procedure, you do not have to follow the instructions in "Preparing the
Note:
Origin200 for Servicing." The module system controller can be removed with the system
in place and fully assembled.
The module system controller (MSC) is mounted on a sheet metal carrier to form a single,
assembly. This assembly is housed behind the plastic bezel crossbar that forms the
system front panel (where the status LED is located).
Follow these steps to remove the MSC:
1. Power the system down and turn off the master power switch.
2. Open the front door.
3. Remove the front panel.
With your index finger, press against the catch on the inside of the recess in the
crossbar, on the outside (right or top) of the recess. This recess is where the door
lock fits. See Figure 9-5.
The crossbar swings out, hinging on the far side from the catch. Pull the
crossbar out and set it aside.
