MX304 Power System

SUMMARY 

The MX304 routers support AC, DC, high-voltage alternating current (HVAC) and high-voltage direct current (HVDC) by offering the following power supplies:

  • JNP-PWR2200-AC

  • JNP-PWR2200-DC

  • JNP-PWR2200-HV

The MX304 uses either AC, DC, or HVAC/DC power supply modules. The router contains two power supplies at the rear of the chassis in slots PSM0 through PSM1. The AC, DC, or HVAC/DC power supplies directly plug into the midplane and are located symmetrically on the left side 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 power adapter board, which distributes the different output voltages produced by the power supplies to the router components, depending on their voltage requirements. A minimum of one power supply is required for non-redundant operation. If one power supply in a redundant configuration fails, the second power supply assumes the entire electrical load without interruption. See MX304 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 operates in 1 + 1 PSU redundancy mode. Feed redundancy is not supported.

All of the power supplies are hot-insertable and hot-removable, field-replaceable units (FRUs). The router ships with two power supplies labeled PSU 0 through PSU 1 (top to bottom) in the rear of the chassis. Don't keep the power supply slot empty.

CAUTION:

Do not mix AC and DC power supplies in the same chassis. AC and HVAC can coexist in the same chassis during the hot-swap of AC for HVAC. Do not mix AC and HVAC power supplies in a running environment.

MX304 AC Power System Description

The MX304 uses either AC, DC, or HVAC/DC power supply modules (see Figure 1 ).

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.

CAUTION:

Do not mix AC, DC, or HVAC/DC power supplies in the same chassis.
CAUTION:

Before you begin installing the router, ensure that a licensed electrician has attached an appropriate grounding lug to the grounding cable that you supply. Using a grounding cable with an incorrectly attached lug can damage the router.
CAUTION:

You can prevent AC power cables from being exposed to hot air exhaust by always routing the power cables away from the fan trays and power supplies.

Each inlet requires a dedicated AC power feed and a dedicated customer-site circuit breaker. We recommend that you use a minimum 16 A customer-site circuit breaker, or as required by local code.

Each AC power supply weighs approximately 2.42 lb (1.1 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.

MX304 DC Power System Description

MX304 DC Power System Description

Each DC power supply weighs approximately 2.42 lb (1.1 kg) and consists of a handle, an ejector lever, a status LED, and a terminal block that provides a single DC input (–48/–60 VDC and return). The DC power supply requires a dedicated customer-site circuit breaker. We recommend that you use a dedicated customer-site circuit breaker rated for 60 A (60 VDC), or as required by local code.

CAUTION:

Do not mix AC, DC, or HVAC/DC power supplies in the same chassis.

MX304 High-Voltage AC/DC Universal System Power Description

The MX304 uses either AC, DC, or HVAC/DC power supply modules (see Figure 5).

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.

CAUTION:

Do not mix AC, DC, HVAC/DC power supplies in the same chassis.

Each HVAC/DC power supply weighs approximately 2.42 lb (1.1 kg) and consists of a handle, an ejector lever, an AC anderson inlet, a fan, and an LED to monitor the status of the power supply. Figure 5 shows the power supply.

Each inlet requires a dedicated HVAC or HVDC power feed and a dedicated customer-site circuit breaker. We recommend that you use a minimum 16-A customer-site circuit breaker, or as required by local code.

Warning:

The router is a pluggable type A equipment installed in a restricted-access location. It has a separate protective earthing terminal (sized for M6 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.
