P O E Rj45 (Slot C) - GE MultiLink ML810 Instruction Manual

OPERATION
4.5.20 ML810 (C2), 4 x PoE RJ45 (Slot C)
4–16
The ML810 is available with the option of having PoE capabilities on the four RJ45 ports in
slot C. This is used in conjunction with ML810P-48VDC to add an additional four PoE ports
to the existing four PoE ports in slot A.
The PoE (Power-over-Ethernet) RJ45 ports are similar to regular RJ45 ports, except they
have the capability of providing power on each port to power up attached PD devices, per
the IEEE802.3af PoE standard. The power-pass-through PoE ports are dependent upon the
-48VDC input power to supply the PD power for these RJ45 (10/100) ports. Each port
supplies up to 15watts to power attached PoE PD devices.
The LEDs on the PoE ports are slightly different compared to regular (non-PoE) RJ45 ports.
When the PoE port is in use, the PoE LED is ON when connected properly to an IEEE 803.af
compliant PD device on that port. When non-PoE devices are connected, the PoE LED is
OFF. Operation of Ethernet data traffic is not affected by PoE. LINK and ACTIVITY LEDS are
combined on the PoE modules into one LED that is marked as L/A.
PoE LEDs Summary
For PoE devices, each RJ45 PoE port supports only 802.3af complaint devices. The PoE LED
is ON when the attached PD is drawing power from the port. The power is supplied on the
data pairs, per IEEE802.3af PoE standard.
For non-PoE devices connected, the PoE port will act as a normal RJ45 port and the PoE
LED is OFF. No power is sent out from the port.
The PoE ports in Magnum 6K's with 48VDC power input act as a pass-through, so the
48VDC power input source to the Multilink ML810 must be strong enough to provide power
to the 6K switch and to all 4-RJ45 ports with PD devices connected (up to 15 watts per PoE
port).
In the case where the 48VDC power in not internally connected to the POE port pins and no
power is coming to the PoE ports for some reason, all the PoE port LEDs are ON
simultaneously to indicate a trouble condition. The ports will still operate properly for data
traffic to non-PoE devices.
