Modular Express Ethernet Switch, 8-Port Copper Module, RJ-45

Same Day Shipping (before 5PM ET)
Extended Double Diamond™ Warranty Available (3 Additional Year)

*Required field


The Modular Express Ethernet Switch gives you the ultimate in flexibility. It enables you to quickly adapt the number and type of Ethernet ports to your changing network, so you'll easily customize it to your needs, whatever the combination of copper and fiber ports that you have.

The switch has two slots that you can fill with 8-port modules in combinations of 100-Mbps multimode fiber ports and/or 10/100 RJ-45 copper ports. A third "half" slot is reserved for a 1-port fiber or copper uplink module, so you can even customize it to your input signal!

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 help 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 100-Mbps 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.
