Mounting the Switch in a 19-inch Rack
1. Attach the mounting brackets to both sides of the chassis. Insert screws and tighten with a screwdriver to
secure the brackets. 2. Place the switch on a rack shelf in the rack. Push it in until the oval holes in the brackets
align with the mounting holes in the rack posts. 3. Attach the brackets to the posts. Insert and tighten screws.
Mounting the Switch on Desk or Shelf
1. Verify that the workbench is sturdy and reliably grounded. 2. Attach the four adhesive rubber feet to the
bottom of the switch.
Installing SFP Modules
You can install or remove a mini-GBIC SFP/SFP+ module from an SFP/SFP+ port without having to power off the
switch. Note: The SFP ports should use UL Listed Optional Transceiver product, Rated 3.3Vdc, Laser Class 1.
See the SFP manual for specific cautions, warnings, and instructions. See the Transition Networks SFP page for
our full range of Optical Devices. 1. Verify SFP orientation and insert the module into the SFP port. 2. Press firmly
to ensure that the module seats into the connector.
Connecting Network Devices
The switch is designed to be connected to 10, 100 or 1000Mbps network cards in PCs and servers, as well as to
other switches and hubs. It may also be connected to remote devices using optional SFP transceivers.
Installing Twisted-Pair Devices
Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. Use Category 5,
5e, or 6 cable for 1000BASE-T connections, Category 5 or better for 100BASE-TX connections.
Cabling Guidelines
The RJ-45 ports on the switch support automatic MDI/MDI-X, so you can use standard straight-thru twisted-pair
cables to connect to any other network device (PCs, servers, switches, routers, or hubs).
Caution: Do not plug a phone jack connector into an RJ-45 port. This will damage the switch. Use only twisted-
pair cables with RJ-45 connectors that conform to FCC standards.
Connecting to PCs, Servers, Hubs, and Switches
1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector. 2. If the device is a network
card and the switch is in the wiring closet, attach the other end of the cable segment to a modular wall outlet
that is connected to the wiring closet. Otherwise, attach the other end to an available port on the switch. Make
sure each twisted pair cable does not exceed 100 meters (328 ft.) in length. Note: Avoid using flow control on a
port connected to a hub unless it is required to solve a problem. 3. As each connection is made, the Link LED
corresponding to each port lights green (1000 Mbps) or amber (100 Mbps) to indicate a valid connection.
Network Wiring Connections
The punch-down block is an integral part of many equipment racks. It is part of the patch panel. Instructions for
making connections in the wiring closet with this type of equipment follows. 1. Attach one end of a patch cable
to an available port on the switch, and the other end to the patch panel. 2. If not already in place, attach one end
of a cable segment to the back of the patch panel where the punch-down block is located, and the other end to a
modular wall outlet. 3. Label the cables to simplify future troubleshooting.

AC/DC/DC Redundant Power
The three power inputs (AC/DC/DC) are redundant but in active/standby mode. There is failover between the
three inputs but selecting primary and secondary is not supported. To select the primary and secondary inputs:
1. Between AC and DC : Both AC and DC will convert the input power to 12VDC output to the PCB; the design will
compare the voltage of 12VDC output and select the higher voltage as the primary power. If the primary power
fails, the secondary will take over.
2. Between two DC inputs: The DC input with higher voltage is the primary input, the other is the secondary
input.
Selecting the priority between AC and DC is not supported, but you can select between two DC inputs by
adjusting the DC output. See the Install Guide.
Power Connection: Warning: Connect the power supply to the switch first, and then connect the power supply to
power. Otherwise catastrophic product failure may occur.
1. Verify that power is off to the DC circuit that you are going to attach to the switch PoE DC-input connector.
This can be either of the two power supplies (AC-input or DC-input) or site source DC.
2. As an added precaution, place an appropriate safety flag and lockout device at the source power circuit
breaker, or place a piece of adhesive tape over the circuit breaker handle to prevent accidental power restoration
while you are working on the circuit.
Power Disconnection: To disconnect power from the switch after a successfully boot: 1. Turn off power to the
switch. 2. Disconnect the cables.
Connecting the AC Power Cord
You can order one AC Power cord as a separate option. 1. Connect the AC power cord to the AC power receptacle
of switch. 2. Connect the other end of the AC power cord to the AC power outlet. 3. Check the SYS LED. If it is lit,
the power connection is correct.
Connecting the DC Input(s)
Two DC Power Supply options are available (ordered separately): 25131 for 48VDC and
25079 for 24VDC, 76.8Watts. See the Install Guide for details. The SM24DP4XA DC
input is dual +24/+48 VDC or -24V/-48V VDC. 1. Insert the negative/positive DC wires
into the + and - terminals, respectively. 2. To keep the DC wires from pulling loose,
use a small flat-blade screwdriver to tighten the wire-clamp screws on the front of the
terminal block connector. 3. Check the SYS LED. If it is ON, the power connection is
correct.
Initial Switch Configuration via CLI
1. Use an RJ-45 cable to connect a terminal or PC/terminal emulator to the switch
port to access the CLI. 2. Attach the RJ-45 serial port on the switch front panel to
the cable for Telnet/CLI configuration. 3. Attach the other end of the DB-9 cable to
a PC running Telnet or a terminal emulation program such as HyperTerminal or
TeraTerm. 4. After powering up the switch for the first time, you can perform the
initial switch configuration using the CLI (Command Line Interface). For managing
other switch features, see the CLI Reference for details.

Initial Switch Configuration via Web Browser
After powering up the switch for the first time, you can perform the initial
switch configuration using a web browser. For managing other switch features,
see the Web User Guide. To begin the initial configuration stage, reconfigure
your PC’s IP address and subnet mask to make sure the PC can communicate
with the switch. After changing PC’s IP address (for example, 192.168.1.250),
you can access the Web UI of the switch using the switch’s default IP address.
Note: The switch factory default IP address is 192.168.1.77 and the default
Subnet Mask is 255.255.255.0.
1. Power up the PC that you will use for the initial configuration. Make sure the PC has the Ethernet RJ45
connector to be connected to the switch via standard Ethernet LAN cable. 2. Reconfigure the PC’s IP address and
Subnet Mask so that it can communicate with the switch. 3. Power up the switch to be initially configured and
wait until it has finished its start-up processes. 4. Connect the PC to any port on the switch using a standard
Ethernet cable, and check the port LED on the switch to make sure the link status of the PC is OK. 5. Run your
Web browser on the PC; enter the factory default IP address to access the switch’s Web interface. If your PC is
configured correctly, the Login page displays.
