ACX5048 and ACX5096 Power System

AC Power Supply for an ACX5000 Router

The two power supplies in ACX5000 routers are hot-removable and hot-insertable field-replaceable units (FRUs). The power supplies are installed in the router at the factory. You can install replacement power supplies from the management panel without powering off the router or disrupting the router function.

The AC power supply in 1 U ACX5048 is 650 W; the AC power supply in the 2 U ACX5096, is 850 W. Both power supplies look identical. Be sure to use the correct power supply for your chassis product SKU (see Table 1).

CAUTION:

Do not mix power supplies with different wattage. The system raises an alarm when a power supply having a different wattage is inserted into the chassis.

See Figure 1 for an example of the 1 U design and Figure 2 for an example of the 2 U power supply.

The power supply provides port-to-FRU airflow depending on the product SKU you purchase. The power supplies either have labels on the handles that indicate the direction of airflow or they have color-coded handles with a fan icon. See Figure 3 for an example of the power supply. A power supply with the label AFO or a gold-colored handle denotes port-to-FRU airflow.

CAUTION:

Verify that the airflow direction on the power supply handle matches the direction of airflow in the chassis. Ensure that each power supply you install in the chassis has the same airflow direction.

To avoid electrical injury, carefully follow instructions in Connecting AC Power to an ACX5000 Router.

An error has been detected in the power supply. Replace the power supply as soon as possible. To maintain proper airflow through the chassis, leave the power supply installed in the chassis until you are ready to replace it.

Note:

If the AC OK LED and the DC OK LED are unlit, either the AC power cord is not installed properly or the power supply fuse has failed. If the AC OK LED is lit and the DC OK LED is unlit, the AC power supply is installed properly, but the power supply has an internal failure.

DC Power Supply for an ACX5000 Router

The power supplies in ACX5000 routers (see Figure 5) are hot-removable and hot-insertable field-replaceable units (FRUs) that you can install in 1 U DC ACX5048 SKUs of ACX5000 routers without powering off the router or disrupting the routing function.

The DC power supply in 1 U ACX5048 is 650 W with dual feeds for power resiliency. The DC power supply in the 2 U ACX5096 is 850 W with dual feeds for power resiliency. Both power supplies have a similar design and look identical. Be sure to use the correct power supply for your chassis product SKU (see Table 3). See Figure 5 for an example of the 1 U design and Figure 6 for an example of the 2 U power supply.

Note:

The DC power supply in the router has four terminals labeled V–, V–, V+, and V+ (see Figure 7) for connecting DC power source cables labeled positive (+) and negative (–). The V+ terminals are shunted internally together, as are the V- terminals.

AC Power Cord Specifications for an ACX5000 Router

Detachable AC power cords are shipped with the chassis, if you include them as part of your order. 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.

Note:

In North America, AC power cords must not exceed 14.75 feet (approximately 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 that can be ordered for the ACX Series routers are in compliance.
