Poe++ And Poe+ Overview; Monitor Pd Health - NETGEAR MS108EUP User Manual

8-port Ultra60 PoE++ Multi-Gigabit (2.5G) Ethernet Plus Switch

PoE++ and PoE+ overview

Model MS108EUP provides up to 60W PoE++ (IEEE 802.3bt) to each PoE++ port (1–4),
and up to 30W PoE+ (IEEE 802.3at) to each PoE+ port (5–8). The maximum PoE power
budget across all active PoE++ and PoE+ ports is 230W.
The PoE++ and PoE+ power supplied by the switch is prioritized in ascending port
order (from port 1 to port 8), with a total power budget of 230W across all active PoE+
ports.
The following table shows the standard power ranges, calculated with the maximum
cable length of 328 feet (100 meters). If a device receives insufficient PoE power from
the switch, consider using a shorter cable.

Monitor PD health

You can use PD health monitoring to test the health of a PD that is connected to a PoE
port. You can enable automated ping tests that check for connection faults, and you
can restart PoE power to the PD.
Note: Wait a few minutes after attaching the PD before you start the PD health monitor.
To display the status of the PD:
1. Open a web browser from a computer that is connected to the same network as the
switch, or connected directly to the switch through an Ethernet cable.
2. Enter the IP address that is assigned to the switch.
A login window opens.
