EISK8P-GT
Plug and Play Gigabit Switching Hub w/PoE for Automation Systems
Installation Guide
The EISK8P-GT gigabit switching hub is designed for the automation environment.
Like all switches from Contemporary Controls, it features non-blocking (full wire-
speed) operation, but it also complies to the IEEE 802.3af standard for PoE (Power-
Over-Ethernet). All eight Auto-MDIX ports automatically negotiate data rate
(10/100/1000 Mbps) with attached devices — controlling data flow with the PAUSE
function in full-duplex links or the backpressure method in half-duplex links. Ports
5–8 also act as PoE, PSE (Power Sourcing Equipment), with each port providing a
minimum of 12.95 W to a PoE-compliant PD (Powered Device). Each PoE port
exchanges signals with its attached PD and provides the 48VDC PoE power on two
pairs of the Cat5e cable for use by the PD.
The EISK8P-GT supports the 802.3af protocol for powering up devices as follows:
With the switch powered up, an Ethernet cable ties any of ports 5–8 to an attached
device, but the port delivers no power until the attached device is checked for a
valid 25 kΩresistance (the PD signature). Once this value is sensed, the switch
knows that the attached device is a valid PD — so the port applies power on
connector pins 1 and 2 (+48VDC) and 3 and 6 (48V Return) to power the PD.
Using this scheme, ports 5–8 support both PoE or non-PoE devices.
In addition to a power LED, each port has two LEDs for link/activity/rate. The
EISK8P-GT is provided with a writeable label for easy identification of the remote
device attached to each cable. Its 2-pin removable power connector requires
48VDC for operation.

Network Connections
Either straight-through or crossover cables can be used to connect to a non-PoE
Ethernet device that supports Auto–MDI/X or to a PoE powered device. However,
verify that the proper polarity of the PoE power on pins 1, 2, 3, and 6 remains intact.
LED Indicators
The “Power” LED glows solid green when the switch is properly powered. To aid in
troubleshooting, each port has two LEDs. The Port 2 LED labelled “H” glows if a link
exists at 1000 Mbps (green) or at 100 Mbps (yellow). Its LED labelled “L” is normally
unlit but glows yellow if a 10 Mbps link exists. Either the “H” or “L” LEDs flash to show
activity. The LEDs of all other ports are unlabelled but work the same.
Each PoE port has an LED to indicate that the port is delivering power to a PD. The
48V LED indicates proper PoE power and the Fault LED glows red during a PoE power
fault condition.
