“10/100” LED indicating 100Mb when lit (or 10 Mbps when off).
Note: The 10/100 RJ-45 ports are supported with Auto-negotiation and Auto-
crossover (MDIX), which allow the RJ-45 ports to automatically Link with any
RJ-45 device and eliminate the use of cross-over cable.
NOTE: for Power Substations
: In support of the IEEE 1613 Class 2 standard, GCI
advises that, for substation applications, the RJ-45 ports are intended for
connectivity to other communication equipment such as routers or
telecommunication multiplexers installed in close proximity (i.e., less than 2
meters or 6.5ft) to the 6KQ. It is not recommended to use these ports in
substation applications to interface to field devices across distances which
could produce kigh (greater than 2500V ) levels of ground potential rise (GPR)
during line-to-ground fault conditions. The 6KQ passes the 1613specifications
for zero packet loss with fiber ports & with RJ45 ports used as indicated here.
5.2.10 PoE power-pass-through, Base unit Model 6KQP-48VDC, 10/100Mb 4-port
See Section 2.2.3 for basic PoE ports information.
The LEDs on PoE ports are slightly different compared to regular (non-PoE)
RJ-45 modules.. When the PoE port is in use, the PoE LED is ON when connected
properly to a 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 LINK/ACT.
PoE LEDs Summary
For PoE devices, each RJ-45 PoE port supports only 802.3af complaint
devices. The PoE LED is ON when the attached PD is drawing power from the
port.
For non-PoE devices connected, the PoE port will act as a normal RJ-45 port
and the PoE LED is OFF. No power is being 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 source must be strong enough to provide power
to the 6K switch and to all the 4 RJ-45 ports with PD devices connected (up to
15 watts per PoE port).
In the case where the 48VDC power in not internally connected 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.
