Rack and Cabinet Requirements for the SAN192C-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:
v The height of the rack or cabinet must accommodate the 9 RU (15.75 inches or
40.0 cm) height of the switch and its bottom support bracket. The bottom
support bracket ships as a part of the accessory kit for the switch.
v Minimum gross load rating of 2000 lb (907.2 kg) (static load rating) if supporting
four switches.
Clearance Requirements for IBM c-type SAN switches and
directors
You must provide adequate clearance between the chassis and any other rack,
device, or structure so that you can properly install the chassis, route cables,
provide airflow, and maintain the switch. Ensure that the following clearance
requirements are met:
v 7 inches (17.78 cm) between the front of chassis and inside of cabinet.
v 34 inches (86.36 cm) [40 inches recommended (101 cm)] in front of the cabinet so
that a fully loaded 34 inches (86.36 cm) chassis box can be moved.
v 2 inches (5.08 cm) for module handles.
v 3 inches (7.62 cm) between the rear of the chassis and the inside of the cabinet,
that is, the perforated rear door (required for airflow in the cabinet if used).
v 25 inches (63.5 cm) outside of the cabinet to remove fabric modules.
v No clearance is required between the chassis and the sides of the rack or cabinet
(no side airflow).
v Clearance required for cables that connect to as many as 400 ports (in addition
to the cabling required for other devices in the same rack). These cables must
not block access to any removable chassis modules or block airflow into or out
of the chassis. Route the cables through the cable management frames on the left
and right sides of the chassis.
Figure 22 on page 44 illustrates the front, rear, and side clearance requirements for
IBM c-type SAN switches and directors:
