SFP Fiber Ethernet Ports
Up to two 1000 Base fiber SFP slots or two 100/1000 Mbps RJ45 copper ports are available on the ports ‘G1’ and ‘G2’.
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.
For further copper/fiber port combinations, see Chapter 7.1: Hardware Specification.
