Therefore, consideration should be given to installing
the equipment in an environment compatible with the
manufacturer's maximum rated ambient temperature
(Tmra).
•
Reduced Air Flow
: Install the equipment in a rack in
a manner that does not compromise the amount of air
flow required for safe operation of the equipment.
•
Mechanical Loading
: When mounting the
equipment in the rack, ensure that the mechanical
loading is even.
•
Circuit Overloading
: Consideration should be given
to the connection of the equipment to the supply circuit
and the effect that overloading of circuits might have
on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate
ratings should be used when addressing this concern.
•
Reliable Grounding (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 (for example, use of power strips).

Connecting Ethernet Cables
The ports on the Midspan’s front panel are configured as "Pass
Through" ports for 8 (1, 2, 3, 6, 4, 5, 7 and 8) conductors of the RJ-45
connectors. Use Category 5 cabling when making the connections.
1. Connect cables from the Ethernet Switch to the
Data In
ports
(lower row on the front panel).
2. Connect the cables from the IEEE 802.3af ready terminals
(PDs) to the corresponding
Data & Power Out
ports (upper row
on the front panel).
3.6
Connecting Power Cables
When using AC source to power the Midspan, plug in the provided
power cord at the rear AC connector.
3.7
Powering up the Unit
The Power over Ethernet Midspan has no on/off switch. To apply
power to the Midspan or remove power from the Midspan, insert or
remove the power cable from the receptacle (AC) on the rear panel of
the unit.
