Mini-Hub VOL-2008
The VOL-2008, is a compact Dual
Speed, stackable Mini-Hub designed
for work groups or SOHO (small
office/home office) LANs. The
Mini-Hub offers eight dual speed,
auto sensing 10/100T/TX ports
and one 100-FX VF-45™ fiber port.
The VOL-2008 is an unmanaged Hub
with an internal switch engine for
seamless operation on speed mixing
environments. The unit is powered by
an internal auto-ranging power supply
and is housed in a rugged metal case
for greater reliability. In addition, the
VOL-2008 can be stacked up to
4 units high via a DB25 100 Mb
connection located in the rear of the
unit. The VOL-2008 complies with
IEEE 802.3 and 802.3u standards.
