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” on page 43.
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 4 on page 7 shows the details of the power supplies available for EX9214 switches.
