Optional AC Power Supply Assembly

For applications requiring operation from an AC power source, an optional AC Power Supply Assembly
and shelf is available. It provides a source of –48 VDC from 208/240 VAC input. A shelf, separate from
the BPX switch shelf, houses one or two AC Power Supplies and mounts directly below the node
cabinet. This provides a secure enclosure for the power supply assemblies (supplies cannot be removed
without the use of tools).
Two of these supplies are usually operated in parallel for fail-safe redundant operation. The front of the
AC Power Supplies for the BPX switch includes two green LEDs to indicate correct range of the AC
input and the DC output for each individual supply (see Figure 2-4).
