Comtrol ES9528-XT Quick Start - Manual (Page 4)

Connect the SFPs
The ES9528 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. 100BASE-FX is
not supported in Gigabit combo ports.
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 will have priority, thus
no traffic will be sent or received over the corresponding RJ45 connection. To
use the RJ45 connection, remove the corresponding SFP.
