Product Overview
Main Features
  • 2 1/2 slot modular 10/100BASE-TX Fast Ethernet unmanaged rackmountable switch
The Modular Express Ethernet Switch enables you to quickly adapt your Ethernet ports to your changing network. The switch has two slots that you can fill with 8-port modules in combinations of 100Mbps multimode fiber ports or 10/100 RJ-45 copper ports. A third "half" slot is reserved for a 1-port fiber uplink module.

This store-and-forward switch delivers performance! It features a true nonblocking architecture with full wire-speed forwarding. Backpressure and IEEE 802.3x- compliant flow control helps to prevent network congestion. It supports several "smart" features such as port-based VLAN and MAC-based trunking.

The 10/100 copper ports are autosensing for speed and duplex, and they support auto MDI/MDI-X. You can program speed and duplexity as either fixed or autonegotiating. Fiber ports are all 100Mbps Fast Ethernet and come in a choice of ST or SC connectors.

The switch is rackmountable, occupying only 1U of rack space in a standard 19" rack. It has a universal autosensing internal AC power supply. Front-panel LEDs enable you to see status at a glance.

Features two and a half expansion slots: two slots for 8-port modules and a “half“ slot for single-port fiber uplink modules.
Mix and match copper and fiber ports to fit your application.
All copper ports are 10/100Mbps, autosensing for speed and duplex.
