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. Lifetime limited warranty and telephone support 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 OfficeConnect hubs) Indicates how much of the network bandwidth is in use. These LEDs are continually updated to show when the network needs more bandwidth. OfficeConnect hubs come with a user guide, power adapter, one-piece clipping system, and rubber feet.
