Gigabit Ethernet Ports (copper RJ45 or fiber SFP slot)
The Ethernet ports ‘G1’ and ‘G2’ are 1000 Mbps copper RJ45 connectors or 1000 Mbps fiber port SFP slots.
When connecting to a 1000 Mbps fiber port use the SFP slots that accept 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.
