Mounting The Switch In A 19-Inch Rack; Mounting The Switch On Desk Or Shelf; Installing Sfp Modules; Connecting Network Devices - Transition Networks SM24DP4XA Quick Start Manual

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
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.
