MX10003 AC Power System

MX10003 AC Power System Description

The MX10003 uses either AC or DC power supply modules (see Figure 1 ). The router contain six power supplies located at the rear of the chassis in slots PSM0 through PSM5. The AC or DC power supplies directly plug into the midplane and are placed symmetrically on both sides of the chassis for better thermal management. Each power supply has a handle, an ejection lever, and a status LED. The power supplies connect to the baseboard, which distributes the different output voltages produced by the power supplies to the router components, depending on their voltage requirements. A minimum of 3 power supplies are required for non-redundant operation. If one power supply in a redundant configuration fails or is removed, the remaining power supplies assume the entire electrical load without interruption. See MX10003 Component Redundancy for more information on power redundancy supported on the AC and DC powered router. Each power supply is cooled by its own internal cooling system. The chassis is designed to support N+N mode with feed redundancy, and N+1 mode without feed redundancy.

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.


Do not mix AC and DC power supplies in the same chassis.


Routers configured with only one power supply are shipped with a blank panel installed over the power supply slot that is not populated.

Each AC power supply weighs approximately 3.4 lb (1.54 kg) and consists of a handle, an ejector lever, 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 minimum 15-A (110 VAC) customer-site circuit breaker, or as required by local code.


The router is a pluggable type A equipment installed in a restricted-access location. It has a separate protective earthing terminal (sized for M4 hex 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.

AC Power Circuit Breaker Requirements for the MX10003 Router

We recommend that you use a dedicated customer-site circuit breaker rated for 15 A (110 VAC) minimum or 10 A (220 VAC) minimum for each AC power feed, or as required by local code. Doing so enables you to operate the router in any configuration without upgrading the power infrastructure.

AC Power Cord Specifications for MX10003 Routers

A detachable AC power cord is supplied with the AC power supplies. 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 AC power cord provided with each power supply is intended for use with that power supply only and not for any other use.


In North America, AC power cords must not exceed 4.5 meters 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 switch are in compliance.

Table 3 gives the AC power cord specifications for the countries and regions listed in the table.
