Description
Power-Over-Ethernet (PoE) Compatible
The AL-CAT5SW is a Compact Weather Resistant Lightning Protector which provides lightning and surge protection for CAT5 data
applications. The unit is fully compatible with industry-standard Power-over-Ethernet (PoE) devices and 10/100 Base-T Ethernet
networks, providing protection to both Ethernet data pairs as well as the PoE DC power feed. The unit supports both modes A
and B of the 802.3af standard for of supplying DC power. Power can be fed up the CAT5 data pairs, 1-2, 3-6 or using the two
unused pairs, 4-5, 7-8.
High speed semiconductors clamp any voltage, positive or negative on the wires. The limits are +/- 58 volts on the four cable
pairs. The unit is compatible with both normal and inverted polarity voltage PoE equipment. For maximum protection two ALCAT5SW units should be used, one at each end of the CAT5 cable.
This Lightning Protector is compatible with both 10 Base-T and 100-Base devices as well as Power-over-Ethernet (PoE) devices,
including Wireless Access Points, Wireless Client Devices, Access Servers, Outdoor Routers and IP Cameras. A ground lug and
terminal is provided in the lightning protector housing providing superior grounding. The unit also supports the use of shielded
CAT5 cable.
For non-PoE applications this protector can be used for two CAT5 cables, 2-pairs in each cable. Applications include twin IP
camera installations and network devices with dual CAT5 ports.
Optional versions of this unit can be used to protect Telephone and DSL lines as well as
balanced data lines like RS-422/485. The unit will protect up to four balanced twisted
pairs. Please consult the factory for custom versions of the unit. Minimum quantity
requirements apply.
The compact weather resistant housing features a lockable hinged cover and break-away
holes are provided on the rear of the enclosure for mounting. The cable grommet may be
adjusted to cable size and are removable.
