Ventilation Requirements

This section describes ventilation requirements for
the:

■

7-slot chassis

■

8-slot chassis

■

16-slot chassis

Ventilation Requirements for the 7-slot Chassis

The CoreBuilder 9000 Switch 7-slot chassis contains
one fan tray that contains four fans.

To ensure that installed fans are able to provide
adequate ventilation, maintain at least 7 cm (2.76 in.)
between the sides of the 7-slot chassis and the
nearest wall (or other vertical surface). Also provide at
least 91.4 cm (36 in.) behind the chassis to be able to
remove and replace power supplies in the 7-slot
chassis.

When you face the front of the 7-slot chassis, the
inlet is on the right and the exhaust is on the left.

CAUTION:

Operate a CoreBuilder 9000 Enterprise

Switch 7-slot chassis with four fans running. If one
fan in the fan tray fails, replace the fan tray as soon as
possible.

Ventilation Requirements for the 8-slot Chassis
and 16-slot Chassis

The CoreBuilder 9000 Enterprise Switch 8-slot chassis
contains two fan trays. The 16-slot chassis contains
three fan trays. Each fan tray contains three fans.

To remove and replace the fan trays in the 8-slot
chassis and 16-slot chassis, and to maintain proper
cooling, make certain that there is at least 91.4 cm
(36 in.) between the rear of the 8-slot chassis or
16-slot chassis and the nearest wall (or other vertical
surface).

The vent holes at the back of the 8-slot chassis and
16-slot chassis are exhaust vents that cool the power
supply bay. Do not block these vents.

CAUTION:

Do not operate a CoreBuilder 9000

Enterprise Switch 16-slot chassis with fewer than
two fan trays running. Operate the 7-slot chassis and
the 8-slot chassis with a full complement of fans.
