Caution:
The redundant power cord is not hot-swappable.
I. Redundant power input
To make S5000 Series more reliable, redundant power module is provided. The
module has a 12V DC external port, which is connected to Huawei RPS (Redundant
Power System) through DC power cord. The RPS is an external AC-DC or DC-DC
transformer system.
The following figure illustrates the input socket of the redundant power of S5000 Series.

II. Connecting redundant power cord
Step 1: Make sure the switch has been powered off and the RPS DC output has been
turned off.
Step 2: Plug one end of the DC power cord of RPS into the redundant power socket on
the rear panel of the switch and the other end into the DC output socket of RPS.
Step 3: Turn on the switch power and RPS DC output.
Step 4: Check if the state indicator in RPS panel (OK) is on. On means RPS is working
normally. Check if the RUN indicator in the switch panel is blinking. Blinking means the
redundant power input of the switch has been correctly connected.
