BayStack 70 Series 10/100 Ethernet Switches Overview

The BayStack 70-8T, 70-16T, and 70-24T 10/100 Ethernet switches are
autosensing 10/100 Mb/s switches. The BayStack 70-8T 10/100 Ethernet Switch
and BayStack 70-16T 10/100 Ethernet Switch are intended for use on desktops or
other level surfaces. The BayStack 70-24T 10/100 Ethernet Switch can be used
either as a desktop switch or as a segment switch in a wiring closet environment,
mounted in a standard 19-inch equipment rack.

All ports on a BayStack 70 Series 10/100 Ethernet Switches can autosense their
transmission speed to match the best speeds of the connected stations. BayStack
70 Series 10/100 Ethernet Switches ports operate at speeds up to 100 Mb/s. Each
port can autonegotiate with the connected device to operate in full-duplex mode.
If the connected device is operating at half-duplex mode only, or does not have the
capability to participate in the autonegotiation process, the port will default to
half-duplex mode.
