1 Ensure that the device to be connected at the other end of the segment is powered on.
2 Connect the twisted pair segment to the appliance by inserting the RJ45 connector on the twisted
pair segment into the desired RJ45 port.
3 Verify that a link exists by checking that the Activity Link LED is on (solid green or blinking green). If
the Activity Link LED is off, perform the following steps until it is on:
1 Verify that the cabling being used is Category 5 or better, with an impedance between 85 and 111
ohms and a maximum length of 100 meters (328 feet).
2 Verify that the device at the other end of the twisted pair segment is turned on and is properly
connected to the segment.
3 Verify that the RJ45 connectors on the twisted pair segment have the proper pinouts, and check
the cable for continuity.
4 If a link is not established, contact
Data ports 3 and 4 provide QSFP28 ports that can support 40Gbps transceivers, as well as 1, 10, and
25 Gbps transceivers through special adapters. Refer to the
transceivers supported for the E3120.
Installing a Transceiver or an Adapter:
To install a transceiver or adapter:
1 With an antistatic wrist strap attached to your wrist, remove the transceiver from its packaging. If
there is a protective dust cover on the transceiver connector, do not remove it at this time.
2 Hold the transceiver so that the connector will seat properly.
3 Carefully align the transceiver with the port slot.
4 Push the transceiver into the port slot until it clicks and locks into place.
Connecting Cables to Transceiver Ports
To connect cables to transceiver ports:
1 Remove the protective covers from the transceiver and from the connectors on each end of the
cable.
2 Insert the cable connector into the transceiver connector until it clicks into place.
3 Plug the other end of the cable into the appropriate port on the other device. Some fiber-optic
cables may be terminated at the other end with two separate connectors, one for each fiber-optic
strand. In this case, ensure that the transmit fiber-optic strand from the appliance is connected to
the receive port of the other device, and the receive fiber-optic strand on the appliance is connected
to the transmit port of the other device.
4 If a transceiver port is unused, install a dust cover.
Warning
Fiber-optic transceivers use Class 1 lasers. Do not use optical instruments to view the laser
output. The use of optical instruments to view laser output increases eye hazard. When
viewing the output optical port, power must be removed from the network adapter.
