Hardware Installation
The LNK/ACT LED is lit when the cable is correctly connected. Always make sure that the cables between
the switches and attached devices (for example, switch, hub, or workstation) are less than 100 meters (328
feet) and meet these requirements.

Connect SFP Transceivers (Combo Ports 25-28)
The ES7528 equips four Gigabit SFP ports
combined with RJ45 Gigabit Ethernet ports
(Ports 25-28). The SFP ports accept standard
mini GBIC SFP transceivers that support
1000BASE-X (1000BASE-SX/LX/LHX/XD/ZX).
To ensure system reliability, Comtrol
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. Do not 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.
Multi-Mode cables should not exceed 2KM and Single-Mode cables should not exceed 30km.
The SFP cage is 2 x1 design.
