ES1500

PSU

ES1500-24/48 models support redundant, hot-swappable AC power supply modules. The power supply supports input voltage from 100 ~ 127 VAC / 200 ~ 240 VAC. Multiple power supply wattage options are offered to match the desired Power over Ethernet (PoE) requirement of the end user.

  • 1600W1 Power Supply

    2 x 1600W PSUs are used on ES1500-48CP, support F2B (front to back) system and B2F (back to front) airflow direction.

    • F2B (front to back)
    • B2F (back to front)
CAUTION: During normal operation the PSUs do support 1+1 redundancy. If the total system power demand exceeds the power capacity of a single PSU, the PSUs would not support 1+1 redundancy .

  • 920W Power Supply

    2 x 920W PSUs are used on ES1500-24P and support F2B (front to back) system and B2F (back to front) airflow direction.

    • F2B (front to back)

    • B2F (back to front)

CAUTION: During normal operation the PSUs do support 1+1 redundancy. If the total system power demand exceeds the power capacity of a single PSU, the PSUs would not support 1+1 redundancy .

  • 550W Power Supply

    2 x 550W PSUs are used on ES1500-24, ES1500-48C and ES1500-48, and support F2B (front to back) system and B2F (back to front) airflow directions.

    • F2B (front to back)

    • B2F (back to front)

1 Only when this PSU is used in high line mode (200-240V), the output power of the PSU can reach 1600W. When this PSU works in low line mode (100- 127V), the output power of the PSU is reduced to 1000W.
