5.1.20 P6KL4-RJ45, 4 x PoE RJ45 (Slot C)
The 6KL is available with the option of having PoE capabilities on the four
RJ45 ports in slot C. This is used in conjunction with 6KLP-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 Magnum 6KL 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.
