ACX5448, ACX5448-D, and ACX5448-M Power System

AC Power Supply for ACX5400 Routers

The ACX5448 AC router operates at 650 W while the ACX5448-D and ACX5448-M AC routers need 850 W. The two power supply modules (PSMs) in ACX5400 routers are hot-removable and hot-insertable field-replaceable units (FRUs). The PSMs are installed in the router at the factory. You can replace the PSMs without powering off the router or disrupting the router function.

Note:

Both the AFI and AFO PSMs look identical. Be sure to use the correct PSM for your chassis product model (see Table 1 for ACX5448 routers and Table 2 for ACX5448-D and ACX5448-M routers).

CAUTION:

Do not mix PSMs with different airflow in the same chassis. The system raises an alarm when a PSM having a different airflow is inserted into the chassis.

CAUTION:

Do not mix AC and DC PSMs in the same chassis.

Figure 1 shows the AC PSM in ACX5448 routers.

The PSMs provide FRU-to-port or port-to-FRU airflow depending on the product model you purchase. The PSMs either have labels on the handles that indicate the direction of airflow or have color-coded handles with a fan icon. A PSM with the label AFI or a blue handle denotes FRU-to-port airflow. A PSM with the label AFO or a gold-colored handle denotes port-to-FRU airflow.

CAUTION:

Verify that the airflow direction on the PSM handle matches the direction of airflow in the chassis. Ensure that each PSM that you install in the chassis has the same airflow direction. If you install PSM with two different airflow directions, Junos OS raises an alarm. If you need to convert the airflow pattern on a chassis, you must replace all the fans and PSMs at one time to use the new direction.

Table 1 and Table 2 show the different PSMs and their direction of airflow.

AC Power Cord Specifications for ACX5400 Routers

We ship detachable AC power cords 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 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 ACX series power cords comply with the standards.

DC Power Supply for ACX5400 Routers

The two power supply modules (PSMs) in ACX5400 routers are hot-removable and hot-insertable field-replaceable units (FRUs). The PSMs are installed in the router at the factory. The DC power supply in ACX5448 is 650 W and ACX5448-D and ACX5448-M is 850 W with dual feeds for power resiliency. You can install replacement PSMs without powering off the router or disrupting the router function.

Note:

Both the AFI and AFO PSMs look identical. Be sure to use the correct PSM for your chassis product model. You can identify the AFI and AFO PSMs by checking the color of the PSM handles (see Table 5).

CAUTION:

Do not mix PSMs with different airflow. The system raises an alarm when a PSM with a different airflow is inserted into the chassis.

Note:

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