MX104 Power System

 

MX104 Power Overview

The MX104 router uses either AC or DC power supplies (see Figure 1 and Figure 2). The power supplies are located in the front of the chassis and offer 1+1 redundancy. Each power supply has a handle, an ejection tab, and a status LED.

Caution

The router cannot be powered from AC and DC power supplies simultaneously.

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 supply assumes the entire electrical load without interruption. A single power supply provides the maximum configuration with full power for as long as the router is operational. A second power supply can be installed for redundancy. Each power supply is cooled by its own internal cooling system.

Redundant power supplies are hot-removable and hot-insertable. When you remove a power supply from a router that uses only one power supply, the router might shut down depending on your configuration.

AC Power Supplies

Each AC power supply weighs approximately 2.5 lb (1.13 kg) and consists of a handle, a power cord retainer clip, an ejection latch, an AC appliance inlet, a fan, and an LED to monitor the status of the power supply. Figure 1 shows the power supply.

Each inlet requires a dedicated AC power feed and a dedicated customer site circuit breaker. We recommend that you use a dedicated customer site circuit breaker rated for 10 A (100 VAC), or as required by local code.

Warning

The router is pluggable type A equipment installed in a restricted-access location. It has a separate protective earthing terminal (sized for SAE 10-32 ground screws) 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.

DC Power Supplies

Each DC power supply weighs approximately 3 lb (1.36 kg) and consists of a handle, an ejection latch, a status LED, a grounding point, and a terminal block that provides a single DC input (24, –48, or –60 VDC and return) that requires a dedicated customer site circuit breaker. We recommend that you provide at least 40 A @ 24 VDC and use a facility circuit breaker. Figure 2 shows the power supply.

Power Supply LEDs

One LED labeled PS STATUS indicates the status of the power supply. Table 1 describes the system LED in more detail.

On steadily

Power supply is receiving input voltage below the allowable operating range, but the redundant power supply is functioning normally.

Off

Power supply is receiving input voltage below the allowable operating range and is not part of a redundant configuration.

MX104 Power Consumption

The MX104 router supports installation of up to two AC or DC power supplies in slots labeled on the front of the router.

Table 2 lists the power consumed by the MX104 router.

Note

The power consumption values are measured from the power source and are based on systems that contain redundant power supplies, redundant Routing Engines, a fan tray, and are fully loaded with MICs.

Note

We recommend that you use a facility circuit breaker rated for 10 A maximum per inlet at 100 VAC to 240 VAC. Doing so enables you to operate the router in any configuration without upgrading the power infrastructure, and allows the router to function at full capacity using multiple power supplies.

MX104 AC Power Cord Specifications

Each AC power supply has a single AC appliance inlet that requires a dedicated AC power feed. 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.

You can order detachable AC power cords, each approximately 8 ft (2.5 m) long that supply AC power to the router. The C15 appliance coupler at the socket end of the cord, as described by International Electrotechnical Commission (IEC) standard 60320, inserts into the AC appliance inlet coupler. The plug end of the power cord fits into the power source receptacle that is standard for your geographic location.

Table 4 provides specifications on the AC power cord provided for each country or region.
