Overview

Installing the Mounting Hardware on the Chassis

64
Origin200 systems that are configured for rackmounting are shipped from Silicon
Graphics with these components:
• mounting ears and screws to attach them to the Origin200 chassis
• end-caps to cover the mounting ears
• mounting shelf that installs in the equipment rack and supports the weight of the
server
Your equipment rack should provide access to the rear of the server. The rear of the server
is where the main power switch is located, as well as all of the connectors (power,
networking, serial ports, diagnostic port, parallel port, and CrayLink Interconnect port).
Connectors for any PCI options are also at the rear of the server.
See Chapter 1, "Overview of the Origin200 System" for a general description of both
tower and rackmountable installation methods and converting between them.
Caution: If you are installing a two-module Origin200 server, be extremely careful with
the CrayLink Interconnect cable. Do not allow it to become kinked or bent excessively
inside the rack. Be careful not to catch and smash it between the system and other parts
of the equipment rack when sliding the Origin200 chassis in and out.
Each rackmountable Origin200 ships with two mounting ears and 6-32 x 1/4-inch screws
to attach the ears to the server. These ears provide a mechanism to secure the server in
the rack and prevent it from sliding out. The ears do not bear any of the server's weight.
Follow these steps to install the mounting ears on the chassis:
1. Place the Origin200 chassis on a flat, sturdy work surface capable of supporting at
least 40 pounds (18 kg) and up to 75 pounds (34 kg).
Do not install any option drives in the system yet. Drives make the chassis
heavier and more difficult to lift and move.
The system should be flat on the work surface, as shown in Figure 3-1.
