4.1. Faceplate Features
4.1.1. RJ45 Copper Ethernet Ports
To connect to a PC use a straight-through or a cross-over Ethernet cable and when connecting to an Ethernet device
use UTP (Unshielded Twisted Pair) or STP (Shielded Twisted Pair) Ethernet cables.
The switch supports eight 10/100 Mbps copper RJ45 Ethernet ports and up to two 100 Base fiber SFP slots on the
10-port variant and 16 copper 10/100 Mbps RJ45 Ethernet ports on the 16-port variant.

4.1.2. SFP Fiber Ethernet Ports
Up to two 100 Base fiber SFP slots are available on the 10-port variant.
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 combination, see Chapter 7.1/: Hardware Specification.
