III. Power supply system
An S5100-48P-EI switch provides AC power input and RPS DC input. The AC and DC
power inputs can be used at the same time, acting as backup for each other.
Alternatively, you can use either the AC power input alone or the DC power input alone.
Make sure you use an RPS module recommended by H3C as the DC power input.
AC input:
Rated voltage range: 100 VAC to 240 VAC; 50 Hz or 60 Hz
Max voltage range: 90 VAC to 264 VAC; 47 Hz to 63 Hz
DC input
Rated voltage range: -48 VDC to -60 VDC
Max voltage range: -36 VDC to -72 VDC
IV. Cooling system
An S5100-48P-EI Ethernet switch provides two fans for heat dissipation.

I. Front panel
An S5100-26C-EI Ethernet switch provides 24 x 10/100/1000Base-T autosensing
Ethernet ports, four 1000Base-X SFP ports, and one console port on the front panel. An
SFP port and its corresponding 10/100/1000Base-T autosensing Ethernet port form a
Combo port. That is, only one of the two ports forming the Combo port can be used at a
time. Table 1-2 shows the mapping relations between the ports forming the Combo port.
