10/100 autosensing ports

Allows users to connect at either 10 Mbps or 100 Mbps to the hub. The hub will operate at the highest
speed possible, optimizing network performance and user flexibility.

Compact and clippable design

One-piece clipping system lets users connect up to four units in a stack.

External power supply

Provides more flexibility and reduces power requirements in the product, eliminating the need for a noisy fan.

FCC Class B

Indicates that a product is certified for use in domestic as well as office environments (more stringent 
classification than Class A). 

Fully compatible with leading operating systems

OfficeConnect units support Novell NetWare, Microsoft Windows 95, 98, 2000, Windows NT, and other
leading software systems, giving the widest range of backward compatibility with existing office software.

3 Year Hardware Warranty

Provides complete peace of mind.

MDI/MDIX push button switch

Enables direct connection to a server, end station, or another switch or hub, using regular straight-through
cables. 

Network utilization meter (available on most

Indicates how much of the network bandwidth is in use. These LEDs are continually updated to show

OfficeConnect hubs) 

when the network needs more bandwidth.

OfficeConnect hubs come with a user guide, power
adapter, one-piece clipping system, and rubber feet.
