Hardware Installation
Connect Gigabit Ports (Combo Ports 25-28)
Connect the appropriate network cables between the RocketLinx ES7528 Combo 1000BASE-TX (gigabit)/SFP ports (Auto
MDI/MDIX) and the network. The RocketLinx ES7528 includes four RJ45 gigabit Ethernet ports (Ports 25-28). The gigabit
Ethernet ports support 10BASE-T, 100BASE-TX, and 1000BASE-TX.
The gigabit ports are combo ports with SFP Ports 25-28. See
about combo port functionality.
Connect SFP Transceivers (Combo Ports 25-28)
Optionally, connect SFP transceivers. Comtrol
recommends using Comtrol gigabit SFP transceivers.
The RocketLinx ES7528 equips four gigabit SFP ports
combined with gigabit Ethernet ports. The SFP ports
accept standard mini GBIC SFP transceivers that support
1000BASE-SX/LX/LHX/XD/ZX. To ensure system
reliability, Comtrol recommends using a Comtrol
certified gigabit SFP Transceiver. The certified SFP
transceiver includes 1000BASE-SX/LX single/multi
mode range from 550m to 80km.
1.
Plug the SFP transceiver into the SFP fiber
transceiver.
2.
Connect the transmit channel to the receive channel at each end.
3.
Check the direction/angle of the fiber transceiver and the fiber cable.
Note: This is a Class 1 Laser/LED product. Don't stare at the Laser/LED Beam.
The SFP port does not function until the fiber cable is linked to another active device. The SFP and corresponding RJ45 ports
work in an exclusive mode. Traffic sent or received through the SFP module has priority thus no traffic is sent or received over
the corresponding RJ45 connection. To use the RJ45 connection, remove the corresponding SFP.
Connect the Digital or Relay Output
If desired, connect the Digital or Relay Output. The relay contacts are energized, (open) for normal operation and close for
fault conditions. The fault conditions include:
•
Power failure
•
Ethernet port link break
•
Other pre-defined events, which you can configure in the RocketLinx ES7528 user interface. See
for detailed information.
Ground the chassis to earth ground
1.
Insert positive and negative wires into V+ and V-.
2.
Tighten the wire-clamp screws to prevent the wires from coming loose.
