CWGE24MODMS
MODULAR 24 PORT MANAGED SWITCH
V2.02 – October 2010
The ComNet™ CWGE24MODMS Managed Ethernet Switch Chassis provides transmission of twenty-four (24)
Ethernet Ports with the use of three eight port expansion modules. This Ethernet switch is easily configurable by
selecting, sold separately, eight port modules that allow for all copper, optical with four copper and four SFP
modules, or all optical with SFP modules making the CWGE24MODMS switch available for use with either
conventional CAT-5e copper or optical transmission media. The 24 electrical ports support the 10/100/1000
Mbps Ethernet IEEE 802.3 protocol, and auto-negotiating and auto-MDI/MDIX features are provided for
simplicity and ease of installation. These network managed layer 2 switches are optically (1000 BASE-FX) and
electrically compatible with any IEEE 802.3 compliant Ethernet devices. Plug-and-play design ensures ease of
installation, and no electrical or optical adjustments are ever required. The CWGE24MODMS incorporates LED
indicators for monitoring the operating status of the managed switch and network. The CWGE24MODMS and its
corresponding modules are designed for installation in benign (0º – +45º C) operating environments.

    Troubleshooting This section is intended to help you solve the most common problems that may occur on the CWGE24MODMS Managed Switch. Incorrect connections  The switch port can automatically detect straight or crossover cable when linked with another Ethernet device. For the RJ45 connection, use correct UTP or STP cables. The 10/100/1000Mbps port uses 2-pairs twisted cable and the Gigabit 1000T port uses 4 pairs twisted cable.
  • Page 78 Improper Network Topologies  It is important to make sure that you have a valid network topology. Common topology faults include excessive cable length and too many repeaters (hubs) between end nodes. 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.
