Each AC power supply weighs approximately 5.0 lb (2.3 kg) and consists of one AC appliance inlet, one AC input switch, a fan, and LEDs to monitor the status of the power supply. For existing power supplies, each inlet requires a dedicated AC power feed and a dedicated 15 A (250 VAC) circuit breaker.
For high-capacity power supplies, each inlet requires a dedicated AC power feed and a dedicated 16.0 A @ 100 VAC or 11.0 A @ 200 VAC circuit breaker, or as required by local code.
The maximum inrush current for a high-capacity AC power supply is 49A at 264VAC.
WARNING
The router is pluggable type A equipment installed in a restricted-access location. It has a separate protective earthing terminal (sized for UNC 1/4-20 ground lugs) provided on the chassis in addition to the grounding pin of the power supply cord. This separate protective earthing terminal must be permanently connected to earth.
AC Power Supply Configurations
The MX240 high-capacity and normal-capacity power supplies each support either of the following AC power configurations:
In the low-line (110 V) AC power configuration, the MX240 router contains either two AC power supplies (nonredundant), located horizontally at the rear of the chassis in slots
PEM0
and
PEM1
(left to right); or four AC power supplies (redundant), located in slots
PEM0
through
PEM3
(left to right). The low-line configuration requires two power supplies, and the third and fourth power supplies provide redundancy. Each AC power supply provides power to all components in the router. When two power supplies are present, they share power almost equally within a fully populated system. If one power supply in a redundant configuration fails or is removed, the remaining power supplies assume the entire electrical load without interruption. Two power supplies provide the maximum configuration with full power for as long as the router is operational.
In the high-line (220 V) AC power configuration, the MX240 router contains one or two AC power supplies, located horizontally at the rear of the chassis in slots
PEM0
and
PEM2
(left to right). The high-line configuration requires one power supply, with the second power supply providing redundancy. Each AC power supply provides power to all components in the router. When two power supplies are present, they share power almost equally within a fully populated system. If one power supply fails or is removed, the remaining power supply assumes the entire electrical load without interruption. One power supply can provide the maximum configuration with full power for as long as the router is operational.

MX240 AC Power Supply LEDs
Each AC power supply faceplate contains three LEDs that indicate the status of the power supply. The power supply status is also reflected in two LEDs on the craft interface. In addition, a power supply failure triggers the red alarm LED on the craft interface.
