4.4 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
equipment in an environment compatible with 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 airflow
required for safe operation of the equipment.
•Mechanical Loading: While mounting the equipment into a rack, ensure that mechanical loading is even.
•Circuit Overloading: Consider the connection of equipment to supply circuit and the effect overloading of
circuits might have on over-current protection and supply wiring. Appropriate consideration of equipment
nameplate ratings must be given while addressing this concern.

5.2 Troubleshooting Steps
The following table provides a problem and resolution sequence to assist in troubleshooting minor operating
problems. If the following steps do not solve your problem, contact the dealer for further assistance.
Table 5-1.
Problem Corrective Steps
Midspan does not power up. 1. Ensure that the power cord is properly connected.
2. Verify voltage at power inlet is between 100VAC and 240VAC.
3. Remove and reapply power to device and check indicators during
power–up sequence.
A port indicator is not lit
and corresponding PD does not
operate.
1. Verify port is enabled (Midspan did not detect a PD).
2. Verify PD is designed for PoE operation.
3. Verify that you are using a standard Category 5/5e/6, straight-wired
cable, with four pairs.
4. If an external power splitter is in use, replace it with a viable splitter.
5. Verify PD is connected to Data and Power Output port.
6. Try to reconnect the same PD to a different port on the same Midspan
or on another one. If it works, there is probably a faulty output port or
RJ45 connection.
7. Verify port shutdown command was not issued through Web
management.
End device operates, but there is
no data link.
1. Verify port indicator on front panel is continuously lit.
2. If an external power splitter is in use, replace it with a viable splitter.
3. Verify that for this link you are using a standard UTP/FTP Category 5
straight (non-crossover) cabling, with all four pairs, and that link is 100
meters long or less.
4. Try to reconnect the same PD to a different port on the same Midspan
or on another one. If it works, there is probably a faulty port or faulty
RJ45 connection.
