Power Supply Configuration
On a S6700-EI switch, one or two power modules can be configured.
When two power modules are used, they work in 1+1 backup mode to provide power for the
device. In the versions earlier than V200R005C00, the AC and DC power modules cannot be
configured on the same device, while in V200R005C00 and later versions, they can be
configured on the same device.
Figure 2-6 shows the power supply connections of dual DC power modules. After DC power
is transmitted to the PWR module, the PWR module provides -53 V output voltage, and the
motherboard provides power for the entire device.
