Select a Location
Installation: Rack-mount. Use the enclosed screws and brackets to
mount the switch in an open or enclosed 19” rack.
Identify a power source within 6 feet (1.8 meters).
Choose a dry area with ambient temperature between -40 and 75ºC (-
40 and 167ºF).
Keep away from heat sources, sunlight, warm air exhausts, hot-air
vents, and heaters.
Be sure there is adequate airflow.

Connect to the Data Ports
The EX77900 has the following ports:
24 10/100/1000 Mbps copper ports
8 SFP slots shared with ports 17 – 24 supporting 100Mbps or 1Gbps
4 SFP+ slots, supporting 10Gbps or 1Gbps
10/100/1000BASE-TX Ports
Ports 1 to 16 are gigabit copper ports and can be connected to routers,
other switches, or end devices. Use category 5e or higher UTP/STP cable.
1 Gbps Combo/SFP Ports
Ports 17 – 24 are combo ports, and have two physical interfaces for each
port. These ports can be used as either 10/100/1000BASE-TX on the left
section or 1000BASE-FX on the right section. These ports operate in
“either/or” fashion, i.e., connecting to fiber port 17 will render copper
port 17 inoperable.
SFP+ Slots
SFP transceivers can be installed directly into right-side ports 17 – 24 and
SFP ports 1 – 4. Ensure that the same type of transceiver is used at both
ends of the link and that the correct type of fiber cable is used.
5
Connect Power
Terminal Block
If your EX77900 comes with power cables, connect the cables into the
power modules at the back of the switch. If your switch comes with a
terminal block (no cable), then connect the switch to a suitable power
supply using 12 to 24 AWG wire.
Redundant power supply is supported. However, only one power input is
required to operate the switch.
Relay Output Alarm
The switch provides relay output contacts for signaling of a user-defined
power or port failure. The relay output can be connected to an alarm
signaling device.
Normal state: 3 & 2 open, 2 & 1 closed
Alarm state: 3 & 2 closed, 2 & 1 open
Power-Up Sequence
When the switch is powered up:
All
Link/ACT
LEDs blink momentarily.
The
Power 1, 2
LEDs light up and stay lit.
LEDs for every port connected to a device will flash, as the switch
conducts a brief Power On Self-Test (POST).
