available with both multi-mode 850nm (550m), 1310nm (3km), single-mode 1310nm
(10km and 25km) and single-mode 1550nm (40km and 70km) fiber options.
(see page 5 of this manual for part numbers)
The 1000Mb Gigabit SFP fiber-port modules on the Magnum 6KQE are
normally set (factory default) to operate at AUTO mode for best fiber distance and
performance.
LEDs are configured the same as the copper gigabit option. (see Section 5.1.12
above)
The 6KQE-1GSFP 1-port Fiber Gigabit module provides one SFP open
transceiver location that can operate at 10/100/1000Mbps speeds.
5.2 6KQEP-48VDC, Base Unit w/PoE Power-pass-through
The 6KQE is available with the option of having PoE capabilities on the four
fixed RJ45 ports in the base unit (ports 1, 2, 3 and 4).
The PoE (Power-over-Ethernet) RJ-45 ports are similar to regular RJ-45 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 RJ-45
(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) RJ-45 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 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. 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 RJ-45 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 6KQE must be
strong enough to provide power to the 6K switch and to all 4-RJ-45 ports with
PD devices connected (up to 15 watts per PoE port).
