Sun Rack 1000 and Sun Rack 900 Cabinets |
The Sun Rack 1000 and the Sun Rack 900 cabinets can enclose Sun SPARC Enterprise M3000/M4000/M5000 servers, storage products, and qualified third-party equipment.
This document contains the following sections:
The Sun Rack 1000 comes as a 42-rack unit (U) or a 38U enclosure. The Sun Rack 900 comes as a 38U or 36U enclosure. Entry-level and midrange servers can be mounted or preinstalled in these equipment cabinets.
Note - The Sun Rack 1000/900 cabinets have round RETMA rail holes. |

TABLE 1-3 and TABLE 1-4 display system electrical specifications and receptacle model numbers.
TABLE 1-5 lists the allowable vibration for M3000/M4000/M5000 servers in a Sun Rack 1000/900.
For maintenance access, entry-level and midrange servers in racks require a minimum of four feet to the front, three feet to the rear, and three feet from the top. racks can be placed next to each other since there are no side clearance requirements during operation.
Both entry-level and midrange servers must maintain the minimum thermal distance between the rear of the server in an rack (914 mm/36 in.) and any obstructions or walls.
The Sun SPARC Enterprise M3000/M4000/M5000 servers are accessed from the top surfaces. A stepladder may be required for maintenance depending upon the height these servers are mounted in the cabinet. Ensure an adequate service area for maintenance work.
FIGURE 1-6 Front and Rear Maintenance Access and Thermal Specifications
If your existing loading dock meets height or ramp requirements for a standard freight carrier truck, you can use a pallet jack to unload the server. If not, you must provide a standard forklift or other means to unload the server, or request the server be shipped in a truck with a lift gate.
All servers not shipped in an rack should be lifted only by proper computer-lifting equipment to prevent personal injury or damage to server equipment.
Each server that is not preinstalled in an rack is shipped in a separate crate. A pallet jack is required to move each shipping crate to the server location.
Leave each server in its shipping crate until it reaches its final destination. If the crate does not fit through the planned access route, partially disassemble it.
The entire access route to your computer room should be free of raised patterns that can cause vibration, and the route must meet the requirements listed in TABLE 1-6.

As you plan your space needs for the Sun racks, keep these conditions in mind:
The Sun Rack 1000/900 can enclose up to twenty-one 2U M3000 servers, six 6U M4000 servers and three 10U M5000 servers. If you are mounting servers in a Sun Rack 900, an optional cabinet extender is available to extend the depth of the rack from the rear to enable the door to close.
1. Remove the rear door of the rack and set it aside.
2. Place the cabinet extender onto the door hinge pins at the rear of the rack and secure in place. (FIGURE 1-7)
3. Mount the rear door on the cabinet extender.

The Sun cabinet can be permanently mounted to the floor using the same brackets that secured the cabinet to the shipping pallet. The cabinet side of the mounting brackets are slotted to allow for vertical positioning.
