Hardware Installation
You can use the following subsections to install the RocketLinx ES7528:
•
•
Connect the Digital Inputs or Relay Output
•
•
•
Connect SFP Transceivers (Combo Ports 25-28)
•
Connect the Power and Ground
You can use the following procedure to connect power and the ground to the ES7528. The ES7528 is equipped
with both AC and DC1/DC2 power inputs.
1.
Connect the power cord to the AC power input connector.
Note: To reach the maximum total power budget, power inputs must
be aggregated. Refer to the following table for detailed
information.
2.
Connect the DC power inputs.
a.
Insert positive and negative wires (12-24AWG) into the V+ and V-
contacts.
Note: Power should be disconnected from the power supply before
connecting it to the switch. Otherwise, your screw driver
blade can inadvertently short your terminal connections to
the grounded enclosure.
b.
Tighten the wire-clamp screws to prevent the wires from coming loose.
