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).
Table 1 describes the power supply status LED on an AC power supply in an XRE200 External Routing Engine.

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.
The supplied AC power cord is intended for use with the external Routing Engine only and not for any other use.
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.
The DC power supply in an XRE200 External Routing Engine is a hot-insertable and hot-removable field-replaceable unit (FRU).
You install power supplies 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.
DC Power Supply LED in XRE200 External Routing Engines
A DC power supply has one bicolored power supply status LED on its faceplate. This LED displays information about the status of the power supply.
Table 4 describes the power supply status LED on a DC power supply in an XRE200 External Routing Engine.

DC Power Lug Specifications for an XRE200 External Routing Engine
To connect the DC power cables to the external Routing Engine, you must use cable lugs that have the specifications shown in Figure 4.
Before you install an XRE200 External Routing Engine, a licensed electrician must attach a cable lug to the power cables. A cable with an incorrectly attached lug can damage the external Routing Engine.
You must use DC power cables that meet the following specifications: 14-12 AWG (1.9 mm2 minimum) wire, or as required by the local code.
