3.3.1 Grounding
Grounding and wire routing help limit the effects of noise due to electromagnetic interference
(EMI). Run the ground connection from the ground screw to the grounding surface prior to
connecting devices.
Fault Relay
The two sets of relay contacts of the 6-pin terminal block connector are used to detect
user-configured events. The two wires attached to the fault contacts form an open circuit when
a user-configured when an event is triggered. If a user-configured event does not occur, the
fault circuit remains closed.
3.3.2 Redundant Power Inputs
The switch has two sets of power inputs, power input 1 and
power input 2. The top two contacts and the bottom two contacts
of the 6-pin terminal block connector on the switch’s top panel
are used for the two digital inputs. Follow the steps below to wire
redundant power inputs.
Step 1: insert the negative/positive DC wires into the V-/V+ terminals, respectively.
Step 2: to keep the DC wires from pulling loose, use a small flat-blade screwdriver to tighten
the wire-clamp screws on the front of the terminal block connector.
Step 3: insert the plastic terminal block connector prongs into the terminal block receptor on
the switch’s top panel.
3.4 Connection
3.4.1 Cables
10/100/1000BASE-T(X) Pin Assignments
The device has standard Ethernet ports. According to the link type, the switch uses CAT 3, 4,
5,5e UTP cables to connect to any other network devices (PCs, servers, switches, routers, or
hubs). Please refer to the following table for cable specifications.
