Juniper CBL-M-PWR-RA Black 2.5 m

In the AC power configuration, the router can have up to two load-sharing AC power supplies (see AC Power Supply), located at the rear of the chassis in slots PEM0 and PEM1 (left to right). 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. The AC power supplies are fully redundant. If one power supply fails or is removed, the remaining power supply instantly assumes the entire electrical load without interruption. One power supply provides the maximum configuration with full power.

Each AC power supply has two AC appliance inlets. Each requires a dedicated AC power feed. For 100-120 VAC, both inlets are used. For 200-240 VAC, only the top inlet is used. Most sites distribute power through a main conduit that leads to frame-mounted power distribution panels, one of which can be located at the top of the rack that houses the router. An AC power cord connects each power supply to the power distribution panel.

Detachable AC power cords, each 2.5 m (approximately 8 ft) long, are supplied with the router. The C19W (right angle) appliance coupler at the female end of the cord inserts into the appliance inlet coupler, type C13, as described by International Electrotechnical Commission (IEC) standard 60320. The plug at the male end of the power cord fits into the power source receptacle that is standard for your geographical location.
