ACX7024 and ACX7024X Power System
AC Power Supply for ACX7024 and ACX7024X Routers
The power supply modules (PSMs) in ACX7024 and ACX7024X routers are hot-removable and hot-insertable field-replaceable units (FRUs). The PSMs are preinstalled in the router. You can install replacement PSMs without powering off the router or disrupting the router function.
This device is designed to support overvoltage category II (OVC II). If the equipment is subjected to transient voltages greater than OVC II, it will need additional external protection. Ensure that the component you use for this external protection complies with IEC 61643/UL 1449 based on the local code.
Do not use AC and DC PSMs together in the same chassis.
Figure 1 shows the AC PSM for ACX7024 and ACX7024X routers.

AC Power Supply Airflow
Each PSM has its own internal cooling system. The PSMs in ACX7024 and ACX7024X routers support back-to-front airflow (airflow in or AFI). This is because the PSMs on ACX7024 and ACX7024X routers are installed on the front panel of the chassis and the ACX7024 and ACX7024X chassis supports front-to-back airflow (airflow out or AFO). The AFI airflow of the PSMs supports the AFO airflow of the ACX7024 and ACX7024X chassis.
The ACX7024 and ACX7024X AC power supply model number is JPSU-400W-AC-AFI.

AC input voltage | Operating range: 90 VAC to 264 VAC |
AC input line frequency | 50 Hz - 60 Hz |
AC input current rating | 6 A at 100 VAC 3 A at 200 VAC |
Typical power consumption (without optics) at 25 ℃ | 97 W |
Maximum power consumption (without optics) | 150 W |
AC Power Cord Specifications for ACX7024 and ACX7024X Routers
Each AC power supply has a single AC appliance inlet that requires a dedicated AC power feed. The coupler for the AC power cord 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.
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.
Table 2 lists the AC power cord specifications for each country or region.

AC Power Supply Module LEDs on ACX7024 and ACX7024X Routers
The AC power supply module (PSM) on an ACX7024 and ACX7024X router uses two LEDs to indicate power status. Figure 2 shows the location of the LEDs on the AC PSM.

1 — PWR LED | 2 — FAIL LED |
Table 3 describes the LEDs on the AC PSMs.
Name | Color | State | Description |
---|---|---|---|
PWR | Unlit | Off | The PSM is receiving no input power. |
Green | On steadily | The PSM is receiving input power. | |
FAIL | Amber | On steadily | An error is detected in the PSM. Replace the PSM as soon as possible. To maintain proper airflow through the chassis, leave the PSM installed in the chassis until you are ready to replace it. |
