PSU Power Options

ES1000 supports redundant hot-swappable AC power supply units. The power supply support input voltage from 100V-240V. Multiple power supply wattage options are offered to match the desired Power Over Ethernet requirement of the end user.

1600W PSU

2 x1600W PSUs are used in the ES1000-48P and the ES1000-48CP, supporting F2B and B2F airflow.

Note: When operating within a voltage range of 200-240V (high line mode), the PSU can deliver an output power of 1600W. However, in low line mode (100-127V), the output power is reduced to 1000W. The PSU does not support 1+1 redundancy if the total system power demand exceeds the capacity of a single power supply.

920W PSU

2 x 920W PSUs are used in the ES1000-24P, supporting F2B and B2F airflow.

F2B (front to back)
B2F (back to front)

Note: The PSU does not support 1+1 redundancy if the total system power demand exceeds the power capacity of a single PSU.

550W PSU

2 x 550W PSUs are used in the ES1000-24, ES1000-48C and ES1000-48, supporting F2B and B2F airflow.

F2B (front to back)
B2F (back to front)

CAUTION: The airflow of the PSUs and Fans must be same F2B or B2F. Do not mix different airflow types within the chassis.

PoE Description

ES1000-24, ES1000-48 and ES1000-48C are non-PoE SKUs.

ES1000-24P, ES1000-48P, and ES1000-48CP are PoE SKUs. These SKUs support PoE Type 4 Class 8.

Note: For PoE power supply, it is recommended to use CAT 5e or higher, pure copper twisted pair network cable.

SKU ID	PSU	System	Max Power/Port	PoE Budget	Note
ES1000-24P	2 x 920W	200W	90W	1550W	Up to 17 ports x 90W at the same time
ES1000-24P	1 x 920W	200W	90W	630W	Up to 7 ports x 90W at the same time
ES1000-48P ES1000-48CP	2 x 1000W	200W	90W	1710W	Up to 19 ports x 90W at the same time
ES1000-48P ES1000-48CP	1 x 1000W	200W	90W	710W	Up to 7 ports x 90W at the same time

Note: When operating in low line mode (100-127V), the output power of the 1600W PSU is reduced to 1000W, while the 920W PSU maintains the same output power in both high line and low line modes.
