To maintain proper air flow within the chassis and to comply with Electro Magnetic
Interference (EMI) regulations, front panels must be installed on all empty slots.
Hence, PM5000 slots that have no cards installed, need a front panel (P/N: PM 5000-
FRONT PANEL) to be inserted. Each panel has a air baffle on the right hand side.
This air baffle ensures that air flow from the fan units blow only over the inserted
cards. It is critical to have front panels inserted into every “open” slot.

2.10 Fan Unit
The PM 5000 uses a hot-swappable modular fan-unit, (P/N: PM5000-FAN-1) that can
be replaced while the system is running.
To replace a new fan, unscrew the screw below and pull out the fan. Replace the fan
and shut the slot followed by tightening the screw.
