Hardware Installation
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.
