1.1.3 Vibration Limitations

TABLE 1-5 lists the allowable vibration for M3000/M4000/M5000 servers in a Sun Rack 1000/900.

TABLE 1-5 Allowable Vibration for the M3000/M4000/M5000 Servers

Table listing the allowable vibration for M3000/M4000/M5000 server in a Sun Rack 1000/900.

1.1.4 Space and Thermal Specifications

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.

1.1.5 Service Area

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.

1.1.6 Access Route

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.

TABLE 1-6 Access Route Requirements
	With Shipping Pallet	Without Shipping Pallet
Minimum door height	2184 mm/86 in.	2019 mm/79.5 in.
Minimum elevator depth	1506 mm/59.3 in.	1506 mm/59.3 in.
Maximum incline	10˚	10˚

Minimum elevator, pallet jack, and floor loading capacity (maximum weight per server)		544 kg (1200 lb)

Table listing access route requirements.

1.1.7 Server Guidelines

As you plan your space needs for the Sun racks, keep these conditions in mind:

Each rack containing midrange servers requires its own power cords, connected to separate power outlets. See Electrical Specifications, for details on electrical requirements.

Circuit breakers are supplied by the customer as required by local, state, or national electrical codes.

The servers require electrical circuits that are grounded to earth.

1.2 Mounting Specifications

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.

1.2.1 Installing the Cabinet Extender (Optional)

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.

Figure showing how to install the Cabinet Extender.

1.3 Stabilizing the Cabinet

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.

FIGURE 1-8 illustrates a mounting bracket on a Sun Rack 1000 and the hole spacing required to secure the cabinet permanently to the floor.
