Cooling System
The cooling system in an EX9214 switch is a field-replaceable unit (FRU). It consists of
two fully redundant hot-removable and hot-insertable fan trays and an air filter and
provides front-to-back chassis cooling. See Cooling System and Airflow in an EX9214
Switch.
Power Supplies
Power supplies for the EX9214 switch are fully redundant, load-sharing, and
hot-removable and hot-insertable FRUs. Each EX9214 switch chassis can hold up to four
AC or DC power supplies. The power supplies connect to the midplane, which distributes
the power to the switch components depending on their voltage requirements.
Table 38 on page 95 shows the details of the power supplies available for EX9214
switches.

An AC-powered, base-configuration EX9214 switch ships with three 200–240 VAC AC
power supplies. An AC-powered, redundant-configuration EX9214 switch ships with four
200–240 VAC AC power supplies. See AC Power Supply in an EX9214 Switch.
A DC-powered, redundant-configuration EX9214 switch ships with four –40 VDC through
–72 VDC DC power supplies. See DC Power Supply in an EX9214 Switch.
CAUTION: Do not mix different types of power supplies (AC and DC) in the
same chassis.
