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
Switch" on page 43.
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 4 on page 7 shows the details of the power supplies available for EX9214 switches.
Input Voltage
200–240 VAC
–40 VDC through –72 VDC
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
A DC-powered, redundant-configuration EX9214 switch ships with four –40 VDC through
–72 VDC DC power supplies. See
CAUTION: Do not mix different types of power supplies (AC and DC) in the
same chassis.
