SFP Fiber Ethernet Ports
The Ethernet ports ‘G4’ and ‘G3’ are dedicated Gigabit fiber SFP slots. The Ethernet ports ‘G1’ and ‘G2’ are either Gigabit
SFP fiber slots or Gigabit RJ45 copper Ethernet ports
When connecting a 1000 Mbps fiber Ethernet port use the SFP slot that accepts plug in fiber transceivers that
typically have an LC style connector and are available with multimode, single mode, long-haul (for connectors up to
80+ km) or special-application transceivers.
For each fiber port there is a transmit (TX) and receive (RX) signal. When making fiber optic connections ensure that
the transmit (TX) port of the switch connects to the receive (RX) port of the other device, and the receive (RX) port of
the switch connects to the transmit (TX) port of the other device.

Laser!
To avoid ocular exposure and a possible eye injury:
•
Do not attempt to view optical connectors that might be emitting laser energy
•
Do not power up the laser without connecting the laser to the optical fiber and
putting the cover in position, as laser outputs will emit infrared laser light at this
point.
