ACX7348 Power System

SUMMARY The ACX7300 power system includes AC and DC power supply modules and related cords, cables, and cable lugs. The power supply modules (PSMs) operate within specified ranges and are equipped with alarms and indicators.

The ACX7348 router has preinstalled AC or DC power supply modules (PSMs). The PSMs are hot insertable and hot removable FRUs and provide power of 2200 W to the router. You can install two PSMs on ACX7348 routers to provide full power redundancy to the device. Each PSM provides power to all the components in the router. If one PSM fails, or if you remove one PSM, the second PSM balances the electrical load without interruption. Each PSM has its own internal cooling system.

ACX7348 AC Power Supply Module Description

Each 2200-W AC power supply module (PSM) has a single AC input and provides 12-V power to the router and its components.

Table 2: ACX7348 AC PSM LED Color and State

LED Color

Power Supply State

Off

The PSM does not have AC power.

Solid green

The PSM is on and functioning properly.

Blinking green

The PSM is in standby state or other PSM in chassis is ON with 12VSB (vestigial sideband).

Solid amber

The PSM shuts down because of a critical event such as high temperature, high power, high current, or fan failure.

The power cord is unplugged or one of the PSMs has no power.

Blinking amber

The PSM is operating, but there are warning events. Possible causes include high temperature, high power, high current, or a slow fan.

ACX7348 AC Power Cord Specifications

We ship detachable AC power cords with the AC PSMs. The plug end of the power cord fits into the power source outlet that is standard for your geographical location.

ACX7348 DC Power Cables

You must supply DC power cables that meet the specifications required by the local code, laws, and standards. The ACX7348 supports a 6 AWG and 75 °C temperature-rated stranded copper wire.

CAUTION:

You must ensure that power connections maintain the proper polarity.
Warning:

For field-wiring connections, use copper conductors only.
Warning:

Make sure that DC power cables do not block access to ACX7348 components or lie on the ground where people can trip on them.

ACX7348 DC Power Cable Lugs

The accessory box shipped with the ACX7348 router includes the cable lugs that attach to the terminal studs of each PSM.

Figure 5: Physical Specifications of ACX7348 DC Power Cable Lugs Physical Specifications of ACX7348 DC Power Cable Lugs
CAUTION:

Before you begin to install the ACX7348 router, have a licensed electrician attach a cable lug to the power cables that you supply. A cable with an incorrectly attached lug can damage the ACX7348 router.
