NTRODUCTION
In the modern business environment, communication and sharing
information is crucial. With computer networks becoming larger
and more complex, a constant power supply is vital to the
operation of our organization. Your computer system relies on the
battery backup of an Uninterruptible Power System (UPS) to
maintain network integrity when the main power source fails.
The SuperStack II UPS Management Module provides network
power management through UPS monitoring and control. The
Management Module is shipped with default settings that you can
change to meet the needs of your organization.
Networking Terminology
A
Network
is a collection of workstations (for example,
BM-compatible personal computers) and other equipment (for
example, printers), connected for the purpose of exchanging
information. Networks vary in size, some are within a single room,
others span continents.
Ethernet
is a type of local area network, referring to the
technology used to pass information around the network.
10BASE-T
is the name given to the Ethernet protocol that runs
over
Unshielded Twisted-Pair (UTP)
cable. The Management
Module uses an RJ-45 connector for connecting your network.
Token Ring
is the name given to a network that uses token
passing technology in a sequential manner. Token Ring networks
use unshielded twisted-pair (UTP) cable or
Shielded Twisted-Pair
(STP)
cable. The Management Module uses either an
RJ-45
connector or a
9-pin
connector for connecting your network.
