2 What Else You Need
Category 5e or better cable for RJ-45 ports
Appropriate fiber cables for fiber ports
Appropriate SFP cable and modules for SFP ports
Personal computer with a DB-9 male interface (if switch is to be
managed through console port)
3 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.
4 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).

6 Front Panel LEDs
LED Panel Layout
Green LED ON = network connection established
FLASHING = Port sending or receiving data

7 Console Configuration
Connect to the switch console by connecting the DB-9 cable to the
console port of the switch and to the serial port of the computer
running a terminal emulation application (such as Hyperterminal or
Putty).
Configuration settings of the terminal-emulation program: Baud rate:
115,200bps, Data bits: 8, Parity: none, Stop bit: 1, Flow control: none.
The default login name is “root,” no password.
8 Web Configuration
Log in to the switch by launching a web browser and entering
192.168.1.10 in the address bar.
Enter the default login ID: root (no password) and click “Login.”
9 Copy Configuration to USB
The USB port can be used to save the running switch configuration to a
(FAT32) USB storage device. Plug the device into the USB port, and use
the “Save Configuration” command in the web interface, or “copy
running-config startup-config” in the CLI.
10 Other Information
The power cord must be connected to a properly earth grounded outlet.
Rack Mount Instructions - The following or similar rack-mount instructions
are included with the installation instructions:
(A) Elevated Operating Ambient - If installed in a closed or multi-unit
rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient. Therefore,
consideration should be given to installing the equipment in an
environment compatible with the maximum ambient temperature (Tma)
specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be
such that the amount of air flow required for safe operation of the
equipment is not compromised.
C) Mechanical Loading - Mounting of the equipment in the rack should be
such that a hazardous condition is not achieved due to uneven
mechanical loading.
D) Circuit Overloading - Consideration should be given to the connection
of the equipment to the supply circuit and the effect that overloading of
the circuits might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
E) Reliable Earthing - Reliable earthing of rack-mounted equipment
should be maintained. Particular attention should be given to supply
connections other than direct connections to the branch circuit (e.g. use
of power strips).
The socket-outlet shall be installed near the equipment and shall be
easily accessible.
Do not disable the power cord grounding plug. The grounding plug is
an important safety feature.
Plug the power cord into a grounded (earthed) electrical outlet that
is easily accessible at all times.
This equipment is intended to be used in a restricted access location and
be used by a qualified person.
Caution:
This equipment shall be used with all power supplies connected
simultaneously.
Hazardous voltages may occur within this unit when connected to all
power supplies. Prevent access to hazardous voltages by disconnecting
this equipment from all power supplies.

Part I, CSA C22.1. An IEC certified or UL listed single-phase type circuit-
breaker, rated maximum 20A, shall be installed between mains circuit
and equipment.
Thumbscrews should be tightened with a tool after both initial
installation subsequent access to the panel.
Caution:
This equipment has a connection between the earthed conductor of the
DC supply circuit and the earthing conductor. All of the following
installation conditions must be met.
This equipment shall be connected directly to the DC supply system
earthing electrode conductor or to a bonding jumper from an earthing
terminal bar or bus to which the DC supply system earthing electrode
is connected.
This equipment shall be located in the same immediate area (such as
adjacent cabinets) as any other equipment that has a connection
between the earthed conductor of the same DC supply circuit and the
