Physical interface modules (PIMs) are removable and can be inserted into a slot
when the device is powered off. If a slot is unoccupied, a PIM blank panel must be
installed to shield the empty slot and to allow cooling air to circulate properly
through the chassis.
The SSG 500M Series devices support the following PIMs:

Dual-Port T1 or E1
Dual-Port T3
Four-Port Fast Ethernet
