Installation Factors
Follow the installation factors carefully:
•
Elevated Operating Ambient Temperature
: If installed in a closed or multi-unit rack assembly, operating
ambient temperature in rack environment may be greater than room ambient temperature. Therefore, install the
equipment in an environment compatible with manufacturer's maximum rated ambient temperature (T
mra
).
•
Reduced Air Flow
: Install the equipment in a rack in a manner that does not compromise the amount of airflow
required for safe operation of the equipment.
•
Mechanical Loading
: While mounting the equipment in a rack, ensure that the mechanical loading is even.
•
Circuit Overloading
: Consider the connection of the equipment to a supply circuit and the effect overloading of
the circuits might have on over-current protection and supply wiring. Appropriate consideration of the equipment
nameplate ratings must be given while addressing this concern.
•
Reliable Grounding (Earthing)
: Maintain reliable earthing of rack mounted equipment. Pay attention to supply
connections, other than direct connections to branch circuit (for example, the use of power strips).

Connecting Ethernet Cables
The ports on the front panel of Midspan are configured as
Pass Through
ports for eight (1, 2, 3, 6, 4, 5, 7, and 8)
conductors of RJ45 connectors. Use Category 5 cabling while making connections.
1.
Connect cables from Ethernet switch to data in ports (lower row on front panel).
2.
Connect cables from IEEE 802.3at or IEEE 802.3af ready terminals (PDs) to corresponding
Data & Power
Out
ports (upper row on front panel).
