The S5500-28F-EI is delivered with a hot-swappable power module by default. You can
install another one for backup.
The other three models of the S5500-EI Switch Series are designed with two fixed power
receptacles respectively. The two power inputs can be simultaneously used, acting as
backup for each other. Alternatively, you can use either power input.

DC
• Rated voltage range: –48 VDC to –60 VDC
• Input voltage range: –36 VDC to –72 VDC
You can use the –48 VDC power supply in the equipment room, or an external RPS
power supply unit recommended by H3C to provide power supply. For relevant
information, see the RPS Ordering Guide for H3C Low-End Series Ethernet Switches.
RPS
The rated voltage range is 10.8 VDC to 13.2 VDC. Use the external RPS power supply
units recommended by H3C only. For relevant information, see the RPS Ordering Guide
for H3C Low-End Series Ethernet Switches.
