Make sure there is enough clearance around the switch to allow attachment of cables, power cord and allow air circulation. Attaching Rubber Feet A. Make sure mounting surface on the bottom of the Switch is grease and dust free. B. Remove adhesive backing from your Rubber Feet. C.
Rack-mounted Installation The CWGE2FE24MODMS switch comes with a rack-mounted kit and can be mounted in an EIA standard size, 19-inch Rack. The switch can be placed in a wiring closet with other equipment. Perform the following steps to rack mount the switch: A. Position one bracket to align with the holes on one side of the switch and secure it with the smaller bracket screws. Then attach the remaining bracket to the other side of the switch. Attach mounting brackets with screws B.
Note: For proper ventilation, allow about at least 4 inches (10 cm) of clearance on the front and 3.4 inches (8 cm) on the back of the switch. This is especially important for enclosed rack installation. Power On Connect the power cord to the power socket on the rear panel of the switch. The other side of power cord connects to the power outlet. The internal power supply of the switch works with voltage range of AC in the 100-240VAC, frequency 50~60Hz.
3. Network Application This section provides you a few samples of network topology in which the switch is used. In general, the CWGE2FE24MODMS switch is designed as a segment switch. That is, with its large Address table (8000 MAC Address) and high performance, it is ideal for interconnecting networking segments. Personal computers, workstations and servers can communicate each other by directly connecting with CWGE2FE24MODMS switch.
Connecting to the Switch The Console port is a female DB-9 connector that enables a connection to a PC or terminal for monitoring and configuring the Switch. Use the supplied RS-232 cable with a male DB-9 connector to connect a terminal or PC to the Console port. The Console configuration (out of band) allows you to set the switch for remote terminal as if the console terminal were directly connected to it.
4. Console Management Login in the Console Interface When the connection between switch and PC is established, turn on the PC and run a terminal emulation program or Hyper Terminal and configure its communication parameters to match the following default characteristics of the console port: Baud Rate: 9600 bps Data Bits: 8 Parity: none Stop Bit: 1 Control flow: None The settings of communication parameters After finishing the parameter settings, select “OK“.

6. Problem Solving This section is intended to help you solve the most common problems on the CWGE2FE24MODMS switch. Incorrect connections The switch port can auto-detect straight or crossover cables when you link the switch with other Ethernet devices. For the RJ-45 connector use the correct UTP or STP cable, 10/100Mbps port use 2-pair twisted cable and Gigabit 1000T port use 4-pair twisted cable. If the RJ-45 connector is not using the correct pin in the right position, the link will fail.
In addition, you should make sure that your network topology contains no data path loops. Between any two ends nodes, there should be only one active cabling path at any time. Data path loops will cause broadcast storms that will severely impact your network performance. Diagnosing LED Indicators The switch can be easily monitored through panel indicators to assist in identifying problems, which describes common problems you may encounter and where you can find possible solutions.
