Power over Ethernet Plus specifications
Table 6: Avaya VSP 4850GTS and 4850GTS-PWR+ models
Maximum PoE+ W Average PoE+ W on 50 port model
855 W with one power supply
1855 W with two power supplies
15.4 W (802.3af)
17.8 W (802.3.at) — One power supply
32.4 W (802.3at) — Two power supplies
• VSP 4850GTS-PWR+ can support 802.3af 15.4 W on each port with one power supply
installed. You can add a second power supply for redundancy.
• VSP 4850GTS-PWR+ can support 802.3at 32.4 W on each port with two power supplies
installed. PoE+ power reduces to an average of 17.8W on each port with one power supply.
