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 the direct rack environment might be greater than the room ambient temperature.
Therefore, install equipment in an environment compatible with manufacturer's maximum rated ambient
temperature (T
mra
).
•
Reduced Air Flow
: Install equipment in a rack in a manner that does not compromise the airflow required for
safe operation of the equipment.
•
Mechanical Loading
: While mounting equipment on 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 grounding of the rack mounted equipment. Pay attention to
the supply connections, other than direct connections to branch circuit (for example, using power strips).

Connecting Ethernet Cables
Ports on Midspan’s front panel are configured as
Pass Through
ports for eight (1, 2, 3, 6, 4, 5, 7, 8) conductors of
RJ45 connectors. Use Category 5 cabling when making connections.
1.
Connect cables from the Ethernet Switch to
DATA IN
ports (lower row on front-panel).
2.
Connect cables from IEEE 802.3BT ready terminals (PDs) to the corresponding
DATA & POWER OUT
ports
(upper row on front-panel).
5.6
Connecting Power Cables
When using an AC source to power Midspan, plug-in the provided power cord to the back AC connector.
