Feedback Installing the SPARC Enterprise M5000 Server in a Rack

This chapter describes how to mount M5000 servers in a Sun Rack 1000, Sun Rack 900, and Sun Rack II.

The following topics are in this chapter:


6.1 About the M5000 Server

The M5000 server is designed to be mounted in a standard 19-inch rack with a depth of 1000 mm or more. The M5000 is 10 rack units tall (10U) and weighs 125kg (275 lb).

When mounted in a Sun Rack 900, the cabinet extender option is required to enable the rear door to close. See Mounting Specifications.



caution icon Caution - Do not use the handles on the front of the server to lift the server. The front handles are designed for sliding the server in and out of the equipment rack. The handles will not support the weight of the server.


 

caution icon Caution - The M5000 server can weigh up to 125 kg (275 lb). Two people using a computer equipment lift are required to mount the server safely in the rack.

caution icon Caution - For rack stability, place the M5000 server at the lowest open location before filling in the higher areas. Keep the rack’s center of gravity as low as possible.


 

Note - The M5000 server rail kit includes a mounting guide template which can be used to determine hole locations for the rails in the rack.



6.2 Preparing a Sun Rack II

Instructions for Sun Rack 1000 and 900 start in Installing Slide Rails in the Rack.

For a Sun Rack II, you must first install cage nuts in the rack. You must also add nut bar brackets to the rails.

6.2.1 Installing Cage Nuts

Screw hole numbers and rack unit numbers start from the bottom and work upwards. Note that two sizes of cage nuts are used in this procedure.

If you are not familiar with cage nuts, see Appendix A.

1. Install M6 cage nuts for standoffs.

a. Install cage nuts at screw hole #2 at U1 and screw hole #29 at U10 in the left front rack rail (FIGURE 6-3).

b. Repeat Step a for the right front rail.

The rear rails will not have standoffs. This procedure uses a total of four M6 cage nuts.
