5208 or 5877 uninterruptible power supply communications
Uninterruptible power supply support via the Serial to SPCN feature code (1827) is not supported on the
8412-EAD, 9117-MMB, 9117-MMC, 9117-MMD, 9179-MHB, 9179-MHC, and 9179-MHD. Uninterruptible
power supply support may be added by using a 5802 or 5877 expansion unit. SPCN cables are used to
attach the 8412-EAD, 9117-MMB, 9117-MMC, 9117-MMD, 9179-MHB, 9179-MHC, and 9179-MHD, and
5802 or 5877 SPCN ports, as shown in Figure 131. The connection from the uninterruptible power supply
to the 5802 or 5877 is made directly from the uninterruptible power supply to the port labelled P2-T1.
The 1827 is not needed.
