#### Rack Compatibility

Verify that your rack is compatible with the slide rail and cable management arm options. The slide rails are compatible with a wide range of equipment racks that meet the following standards.

Item | Requirement
--- | ---
Structure | Four-post rack (mounting at both front and rear). Two-post racks are not compatible.
Rack horizontal opening and unit vertical pitch | Conforms to ANSI/EIA 310-D-1992 or IEC 60927 standards.
Rack rail mounting hole sizes | Only 9.5 mm square hole and M6 round mounting holes are supported. All other sizes, including 7.2 mm, M5, or 10-32 mounting holes, are not supported.
Distance between front and rear mounting planes | Minimum 622 mm and maximum 895 mm (24.5 inches to 35.25 inches).
Clearance depth in front of front mounting plane | Distance to front cabinet door is at least 27 mm (1.06 inch).
Clearance depth behind front mounting plane | Distance to rear cabinet door is at least 900 mm (35.5 inches) with the cable management arm, or 770 mm (30.4 inches) without the cable management arm.
Clearance width between front and rear mounting planes | Distance between structural supports and cable troughs is at least 456 mm (18 inches).

| Caution - Equipment Loading: Always load equipment into a rack from the bottom up so that the rack will not become top-heavy and tip over. Deploy your rack's anti-tip bar to prevent the rack from tipping during equipment installation.

| Caution - Elevated Operating Ambient Temperature: If the server is installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment might be greater than room ambient temperature. Therefore, install the equipment only in an environment compatible with the maximum ambient temperature (Tma) specified for the server.

| Caution - Reduced Air Flow: Install the equipment in a rack so that the amount of air flow is adequate for the safe operation of the equipment.

| Caution - Mechanical Loading: Mount the equipment in the rack so that the weight is distributed evenly. A hazardous condition can exist with uneven mechanical loading.

| Caution - Circuit Overloading: Do not overload the power supply circuits. Before connecting the server to the supply circuit, review the equipment nameplate power ratings and consider the effect that circuit overloading might have on overcurrent protection and supply wiring.

| Caution - Reliable Earthing: Maintain reliable earthing of rackmounted equipment. Give particular attention to supply connections other than direct connections to the branch circuit (for example, use of power strips).

| Caution - Do not use slide rail mounted equipment as a shelf or a work space.
