The hardware options supporting POE are as follows:
•
iSG18GFP-HV (PoE)-D-8PRJ45-2GSFP-4SFP-4SFP—hardware includes 8 PoE support on the FE Ethernet
ports 1-8. All PoE ports are wired as Alternative-A (PoE runs on the FE twisted pairs). Each port supports up to
30 Watt max PoE. The input for PoE 90-250VAC Note the total PoE power allowed per the unit and per port
group.

6.8.1 Power Management of PoE
1. The eight PoE ports support in total maximum power output of:
a. For 12 VDC powered units: 70 Watt
b. For 24 VDC powered units 90 Watt
c. For 48 VDC powered units : 120 Watt or 240 Watt
d. For 110 VDC powered units : 90 Watt
e. For AC powered units : 120 Watt for 110 VAC or 240 Watt for 220 VAC.
2.
For redundancy purposes, the ports are divided into two groups:
a. Group 1: p1, p2, p3, p6
b. Group 2: p4, p5, p7, p8
6.8.2 Mode of PoE
“Alternative-A” wired ports supply PoE power on demand. Non-PoE equipment connected to such port is protected
as it will not receive power over the Fast Ethernet communication lines.
