24 or 48 VDC
RJ-45 ports: The RJ-45 ports auto-sense for 10 or 100 Mbps
device connections. The auto MDI/MDIX feature allows
connections to switches, workstation and other equipment
without changing straight through or crossover cabling. The
charts below show the cable pin assignments for straight
through and crossover cables.
PoE ports: The PoE ports on this switch follow Alternative A
standards and are limited to 15.4 Watts of power output per
port. Ports 1 thru 4 support the IEEE802.3af standard and
are classified as (PSE) power sourcing equipment, which
means they can be used to power (PD) powered devices.
