DC power supply

The DC-powered chassis of the S12500 Routing Switch Series use the PSE9000-D DC power supply
system, which comprises DC power frames, DC power modules, and power monitoring modules.
DC power frame
Each DC power frame can have one power monitoring module and up to six DC power modules.

NOTE:
Table 2 describes the LED behaviors of the power monitoring module.
A DC power frame has six pairs of wire posts corresponding to power modules 1 to 6, and one
grounding post. The external DC power system supplies power through the six pair of wire posts.
