Appendix A

Cabinet Requirements

The server can be installed into a 19-inch (48.3-cm) wide EIA-compliant cabinet that meets the requirements listed in the table below. You need one Sun Fire 880 server rackmounting kit for each Sun Fire 880 server that you will install into a cabinet.

Cabinet Feature
Requirement

Load Bearing Capacity

The cabinet must firmly support the weight of a Sun Fire 880 server and the mounting hardware (up to 350 lb, 158.8 kg, depending on the server configuration), plus the weight of any other installed devices.

Anti-Tilt Protection

The cabinet must be bolted securely to the floor or equipped with a sturdy and extendable anti-tip leg. You must prevent the cabinet from moving or tilting forward when one or more systems or devices are fully extended from the front of the cabinet.

Vertical Space Requirements

Each server requires 17 rack units (29.75 inches, 75.6 cm) of vertical space for cabinet installation.

Minimum Service Access

An area not less than 3 feet (91 cm) deep must be available in back of the cabinet for server installation and service access.

An area not less than 4 feet (122 cm) deep must be available in front of the cabinet for server installation and server access.

An area not less than 3 feet (91 cm) wide must be available on each side of the server when the server is fully extended on the tray assembly.

When fully extended on the tray assembly, the server will protrude 32.9 inches (83.6 cm) forward of the cabinet's front vertical mounting rails.

Airflow

For proper ventilation of the server, the front and rear doors must comply with the following minimum open area requirements.
60 percent of the area of the front door that is directly in front of the server must be open.
63 percent of the area of the rear door that is directly behind the server must be open.

If the doors of the cabinet do not meet the open area requirements, remove the door or doors that do not comply.

Vertical Mounting Rail Requirements

The cabinet must have two pairs of vertical mounting rails (one pair in front, one in back) that conform to the EIA (RETMA) standard for mounting hole spacing.

Front-to-rear rail spacing must be at least 32 inches (81.3 cm) and not more than 36 inches (91.4 cm) from the outside face of the front rail to the outside face of the rear rail.

Front and rear vertical rail mounting faces must be parallel to each other and to the front plane of the cabinet.

Doors and Panels

Depending on your cabinet, you may need to remove the front and rear door and side panels to access the server or to provide proper ventilation. See Minimum Service Access requirements and Airflow requirements given previously in this appendix.

See the instructions provided with the cabinet for information about removing the front and rear doors and side panels from the cabinet.

EMI Requirements

Electromagnetic interference (EMI) shielding requirements are met by the system chassis and metal side doors, which must remain in place when the unit is installed in the cabinet.

Fire Containment

The cabinet must meet Underwriters Laboratories, Inc. and TUV Rheinland of N.A. requirements for fire containment.
