What’s more, the Palm-Sized
Ethernet Switch and Palm-Sized
Ethernet Switch for Fibre enable
full-wire speed forwarding. They
also provide back pressure and
IEEE 802.3x-compliant flow
control. The switches comply
with other Ethernet standards,
too, including IEEE 802.3 for
10BASE-T and IEEE 802.3u for
100BASE-TX and 100BASE-FX.

All switches include an
internal CPU chip that provides
auto-MDI/MDI-X capability on all
mixed Ethernet ports. The chip
also supports a MAC address
table for 2000 addresses and a
1-MB shared port buffer.

The Palm-Sized Ethernet
Switch and Palm-Sized Ethernet
Switch for Fibre come with an
external, autosensing power
supply that includes a kit of
three separate and detachable
AC power adapters—a 2-prong
adapter for US, a 3-prong adapter
for UK, and a 2-post adapter for
continental Europe. An L-shaped
tool is also included that enables
you to remove one adapter so
another can be installed. Each
adapter is mounted on a plastic
base that slides into and out of the
power supply.
