The external power supply that
comes with the Personal MiniHub is
one of two types: one version for AC
input power of 115 VAC, 60 Hz, and
one version for 230 VAC, 50 Hz. The
115-VAC version has a small trans-
former integral with a convenience
power outlet plug, and a lightweight
DC power cord to the applicable
power jack on the hub. The 230-VAC
version has a small transformer
integral with an IEC-type power plug
for a user-supplied AC power cord
with a convenience power outlet
plug. It also includes a lightweight
DC power cord to connect to the
power jack on the Personal
MiniHub unit.
2.3 Features and Benefits
• Interconnect to an existing
Ethernet network—The
Personal MiniHub provides an
Up-Link switch for port #5 to
be used to connect it into an
existing Ethernet environment
(such as the central hub for the
building or area) via 10BASE-T
wiring.
• Interoperable with other
Ethernet devices—The
Personal MiniHub is completely
interoperable with other
Ethernet-compliant network
devices. Each is fully compliant
with IEEE 802.3 specifications
for 10 Mbps CSMA/CD opera-
tion. This allows the Hub to be
integrated within any standard
Ethernet network and to operate
with all standard software.
• Installation versatility—The
Personal MiniHub is simple
and easy to install in almost any
office or lab location. The tiny
package is very unobtrusive.
• Robust Network Operations—
The Personal MiniHub uses the
“star” network topology and has
automatic per-port partitioning
and reconnection. A fault on
one segment is isolated from the
rest of the network, avoiding
most network downtime.
