XRE200 Power System

 

AC Power Supply in an XRE200 External Routing Engine

An XRE200 External Routing Engine supports two 250 W AC power supplies.

The AC power supply in an XRE200 External Routing Engine is a hot-insertable and hot-removable field-replaceable unit (FRU).

Power supplies are installed in the power supply slots on the back of the chassis. All XRE200 External Routing Engines are shipped with two AC or DC power supplies.

Each AC power supply weighs approximately 2.5 lb (1.1 kg) (see Figure 1).

The 250W AC power supply supports both the low-line (100 VAC) and the high-line (240 VAC) AC power configurations.

AC Power Supply LED in XRE200 External Routing Engines

An AC power supply has one bicolored power supply status LED on its faceplate. This LED displays information about the status of the power supply (see Figure 2).

AC Power Cord Specifications for XRE200 External Routing Engines

Detachable AC power cords are supplied with the external Routing Engine. The coupler is type C13 as described by International Electrotechnical Commission (IEC) standard 60320. The plug end of the power cord fits into the power source outlet that is standard for your geographical location.

Caution

The supplied AC power cord is intended for use with the external Routing Engine only and not for any other use.

Note

In North America, AC power cords must not exceed 4.5 meters (approximately 14.75 feet) in length, to comply with National Electrical Code (NEC) Sections 400-8 (NFPA 75, 5-2.2) and 210-52 and Canadian Electrical Code (CEC) Section 4-010(3). The cords supplied with the external Routing Engine are in compliance.

DC Power Supply in an XRE200 External Routing Engine

An XRE200 External Routing Engine supports two 560 W DC power supplies.

The DC power input (-48 VDC and return) requires a dedicated customer site circuit breaker. We recommend that you use a two-pole 20-amp DC circuit breaker, or whatever is required by local code.

Each DC power supply contains a single DC power input, status LEDs, an ejector lever, handle, and a fan. See Figure 3.
