General Rack and Cabinet Requirements for IBM c-type SAN switches and
directors
You can install the following types of racks or cabinets for your switch:
• Standard perforated-doors cabinets
• Solid-walled cabinets with a roof fan module (bottom to top cooling)
• Standard open four-post Telco racks
• Standard open two post Telco racks
Note : IBM c-type SAN switches and directors are compatible with IBM racks and PDUs.
Use a standard 19 inch, four post Electronic Industries Alliance (EIA) cabinet or rack with mounting rails
that conform to English universal hole spacing per section 1 of the ANSI/EIA-310-D-1992 standard.
The depth of a four post rack or a cabinet must be 24 to 32 inches (61.0 to 81.3 cm) between the front
and rear mounting vertical rails.
Ensure that the airflow and cooling are adequate and there is sufficient clearance around the air vents on
the switch, as described in Appendix A, "Product Specifications," on page 135.
The rack must have sufficient vertical clearance for the chassis along with 2 RU for the shelf brackets, and
any desired clearance for the installation process.
The front and rear doors of enclosed racks must have at least 60% open area perforation pattern.
Additionally, you must consider the following site requirements for the rack:
• Power receptacles must be located within reach of the power cords used with the switch.
• AC power supplies
• Power cords for 3-kW AC power supplies are 8 to 12 feet (2.5 to 4.3 m) long.
• Where necessary, have a seismic rating of Network Equipment Building Standards (NEBS) Zone 3 or
Zone 4, per GR-63-CORE.
Rack and Cabinet Requirements for the SAN768C-6 Chassis
To correctly install the switch in a cabinet located in a hot-aisle/cold-aisle environment, you should fit the
cabinet with baffles to prevent exhaust air from recirculating into the chassis air intake. Work with your
cabinet vendors to determine which of their cabinets meet the following requirements or see the IBM
Support for recommendations:
• The height of the rack or cabinet must accommodate the 25 RU (43.75 inches or 111.1 cm) height of
the switch and its bottom support bracket.
• Minimum gross load rating of 2000 lb (907.2 kg) (static load rating) if supporting two switches.
Rack and Cabinet Requirements for the SAN384C-6 Chassis
The rack must meet the following requirements:
• The minimum vertical rack space per chassis is 24.5 inches (62.2 cm) or 14 RU.
• The width between the mounting rails must be at least 17.75 inches (45.1 cm). For four-post EIA racks,
this is the distance between the two front rails and rear rails.

• Minimum gross load rating of 2000 lb (907.2 kg) (static load rating) if supporting three switches.
