What are the advantages of mid-span power?
The Midspan
eliminates multiple cables to networking
devices by injecting power on the Ethernet
cable. Installation costs as well as desktop
and wall clutter are significantly reduced.
In addition to eliminating multiple cables,
the Midspan allows centralized backup power
for all connected devices. Centralized UPS
backup is less expensive, more reliable and
easier to maintain than individual UPS
backup. The Midspan can be supplied with
backup power from the existing Ethernet
switch UPS or, to increase reliability, with
its own dedicated supplied UPS.
How does the Midspan increase Quality of
Service?
Voice-Over-IP
(VoIP) telephony allows the convergence of
voice and data traffic on a packet switched
data network. Organizations implementing
this technology must provide QoS equivalent
to that of traditional PBX and Centrex
solutions. This requires centralized power
and battery backup for VoIP phone sets to
guard against the loss of AC power and the
resulting loss of phone service. While not
formally termed QoS, other Ethernet
applications such as wireless access points
and security cameras also have high
availability requirements. Midspan coupled
with a UPS, provides simple, centralized,
guaranteed power for VoIP phonesets and
other Ethernet-based applications.
How does the Midspan reduce cost?
The Midspan
allows easy migration to IP-based telephony
with no expansion costs and without the
replacement of expensive network
infrastructure. The Midspan can either be
supplied with battery backup using the UPS
provided by the existing Ethernet switch or
to increase reliability, with its own
dedicated supplied UPS. |
