ACX5048 and ACX5096 Power System

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).

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.

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

Table 1 shows the different power supplies and their direction of airflow.

Figure 4 shows the location of the LEDs on the power supply.

Table 2 describes the LEDs on the AC power supplies.

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.

Table 4 describes the LEDs on the DC power supplies.

Table 5 describes the AC power 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.

Table 6 lists AC power cord specifications provided for each country or region.
