ACX7100-48L Power System

 

AC Power Supply for ACX7100-48L Routers

The ACX7100-48L AC router operates at a maximum of 1600 W. The two power supply modules (PSMs) in ACX7100-48L routers are hot-removable and hot-insertable field-replaceable units (FRUs). The PSMs are preinstalled in the router. You can replace the PSMs without powering off the router or disrupting the router function.

Note

Both the AI and AO PSMs look similar. Be sure to use the correct PSM for your chassis product model (see Table 1).

Caution

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

Caution

Do not use AC and DC PSMs together in the same chassis.

Figure 1 shows the AC PSM in ACX7100-48L routers.

The PSMs provide FRU-to-port or port-to-FRU airflow, depending on the product model that 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 AI or a blue handle denotes FRU-to-port airflow. A PSM with the label AO 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 PSMs with different airflow directions, Junos 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.

AC Power Cord Specifications for ACX7100-48L Routers

We ship detachable AC power cords with the chassis if you include them as part of your order. The coupler is type C15 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 ACX7100-48L Routers

The two power supply modules (PSMs) in ACX7100-48L routers are hot-removable and hot-insertable field-replaceable units (FRUs). The PSMs are preinstalled in the router. The DC power supply in ACX7100-48L is 1600 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 AI and AO PSMs look similar. Be sure to use the correct PSM for your chassis product model.

Caution

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