the operating ambient temperature of the rack environment may be greater than
room ambient. Therefore, consideration should be given to installing the equipment
in an environment compatible with the maximum ambient temperature (Tma)
specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be such that
the amount of air flow required for safe operation of the equipment is not
compromised.
C) Mechanical Loading - Mounting of the equipment in the rack should be such
that a hazardous condition is not achieved due to uneven mechanical loading.
D) Circuit Overloading - Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits might
have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
E) Reliable Earthing - Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other than
direct connections to the branch circuit (e.g. use of power strips)."
3.2 Connecting Ethernet Media
The Magnum DS8016 Dual-Speed Stackable Hubs can be connected to the
following two media types: 100BASE-TX and 10BASE-T. CAT 5 cables should be used
when making 100BASE-TX connections. When the ports are used as 10BASE-T ports, CAT
3 may be used. In either case, the maximum distance for unshielded twisted pair cabling is
100 meters (328 ft).
Media
IEEE Standard Connector
Twisted Pair (CAT 3, 4, 5) 10BASE-T RJ-45
Twisted Pair (CAT 5) 100BASE-TX RJ-45
NOTE : It is recommended that high quality CAT. 5 cables (which work for both 10Mb
and 100Mb) be used whenever possible in order to provide flexibility in a mixed-
speed network, since dual-speed ports are auto-sensing for either 10 and 100Mb/s.
