Figure 9: Fan Module Used in an OCX1100 Switch

CAUTION: You must remove only one fan module at a time for replacement
from the rear panel of the chassis. The switch continues to operate without
thermal shutdown for a limited period of time (30 seconds) during the
replacement of a fan module.
NOTE: Four fan modules must be installed for optimal functioning of the
switch.
The fan modules are available in two models that have different airflow
directions—back-to-front (air enters through the vents on the rear panel of the switch
chassis), indicated by the label

Table 12 on page 18 lists the available fan module models and the direction of airflow in
them.
Table 13 on page 18 shows the direction of airflow in OCX1100-48SX switch models as
shipped.
Fan Modules and Power Supply
The switch ships with four fan modules and
two AC power supplies installed; all bearing
