  • Compact 1.7" height fits standard 17.4" rack width
  • Weighs 8.38 lb for straightforward rack installation

Target Switch and Role

The HPE RPS 800-A is an external redundant power supply designed for the H3C S5500-52C-EI switch. It accepts AC input and delivers selectable DC output to keep the switch running during an internal power supply failure. This unit suits network administrators who need cold-standby backup for a single compatible switch.

Output Voltage Constraints

The supply provides +12 V DC, -54 V DC or both voltages simultaneously depending on which DC output cables are connected. It only activates its DC output when it detects a power supply failure in the powered device, so it does not share load during normal operation. Buyers who need active load-sharing or hot-swap redundancy cannot use this unit.

Upgrade From No Backup

This RPS replaces a configuration with no external power redundancy for the S5500-52C-EI. The jump is worth it when downtime from a single internal supply failure is unacceptable and the switch chassis matches the listed compatibility. It does not support other switch models or higher-wattage requirements.

Kysymyksiä tästä tuotteesta

Which HPE redundant power supply model matches my S5500-52C-EI switch?

The RPS 800-A with part number JD183A is built for the H3C S5500-52C-EI, delivering selective +12 V and -54 V DC backup when the internal supply fails.

What does the 800 W rating mean once the unit is connected to my switch?

It indicates the maximum AC input capacity at 240 V; the RPS only activates its DC outputs (+12 V and -54 V) after detecting an internal power-supply failure in the switch.

What interface does the RPS 800-A use and what does it limit in practice?

It connects through dedicated DC output cables to the S5500-52C-EI, capping backup power to the switch's +12 V and -54 V rails and only engaging on internal supply failure.
