Installing and Maintaining the E1200i System

The E1200i DC system requires a minimum of one DC Power Entry Module (PEM) to operate, but two are
recommended for redundancy. To comply with safety agency and EMI regulations, you must install covers
on all power supply slots not containing a PEM. Connect the PEMs to the appropriate branch circuit
protection as defined by local electrical codes.
recommended for redundancy. To comply with safety agency and EMI regulations, you must install covers
on all power supply slots not containing a PEM. Connect the PEMs to the appropriate branch circuit
protection as defined by local electrical codes.
For full redundancy, each PEM must be attached to an independent power source with a dedicated circuit
breaker. For example, the PEM in slot 0 connects to circuit breaker A and the PEM in slot 1 connects to
circuit breaker B.
breaker. For example, the PEM in slot 0 connects to circuit breaker A and the PEM in slot 1 connects to
circuit breaker B.
The E1200i DC chassis contains two DC PEM slots, as shown in
.

The DC PEM shown in
is used in both the E1200 and E1200i DC chassis.
