Figure 4-3. Installing the Mounting Brackets
4.4 Installation Factors
Follow the installation factors carefully:
• Elevated Operating Ambient Temperature: If installed in a closed or multi-unit rack assembly, the operating
ambient temperature in the direct rack environment might be greater than the room ambient temperature.
Therefore, install the 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 airflow required for
safe operation of the equipment.
• Mechanical Loading: While mounting the equipment on a rack, ensure that the mechanical loading is even.
• Circuit Overloading: Take into consideration the connection of the equipment to the power supply circuit and
the effect that overloading the circuits might have on over-current protection and supply wiring. The equipment
nameplate ratings must be considered 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, the use of power strips).
4.5 Connecting Ethernet Cables
Ports on the Midspan’s front panel are configured as Pass Through ports for eight (1, 2, 3, 6, 4, 5, 7, and 8)
conductors of RJ-45 connectors. Use Category 5e/6/6A cabling while connecting.
1. Connect cables from the Ethernet switch to the DATA IN ports (lower row on the front panel).
2. Connect cables from PoH or IEEE 802.3bt ready terminals (PDs) to the corresponding DATA & POWER OUT
ports (upper row on the front panel).
4.6 Connecting Power Cables
While using an AC source to power Midspan, plug-in the provided power cord to the back of the AC connector.

Table 5-1. Troubleshooting Steps
Symptom Corrective Steps
Midspan does not power up 1. Make sure the power cord is properly connected.
2. Verify that the voltage at power inlet is between 100 VAC and 240
VAC.
3. Remove and reapply power to the device and check indicators
during the power-up sequence.
A port indicator is not lit and
corresponding PD does not operate.
1. Verify the port is enabled (Midspan does not detect a PD).
2. Verify that the PD is designed for PoE operation.
3. Ensure that a standard Category 5/5e/6, straight-wired cable, with
four pairs is used.
4. If an external power splitter is in use, replace it with a viable splitter.
5. Verify that the PD is connected to the DATA & POWER OUTPUT
port.
6. Try to reconnect the same PD to a different port on the same
Midspan or to on another one. If it works, there is probably a faulty
output port or RJ-45 connection.
7. Verify port shutdown command was not issued through web
management.
End device operates, but there is no
data link.
1. Verify that the port indicator on the front panel is continuously lit.
2. If an external power splitter is in use, replace it with a viable splitter.
3. Ensure that this link uses a standard UTP/FTP Category 5e/6/6A
straight (non-crossover) cabling, with all four pairs, and that the link
is no longer than 100 meters.
4. Try to reconnect the same PD to a different port on the same
Midspan or on another one. If it works, there might be a defect in the
port or in the RJ-45 connection.

• Power redundancy
• Power backup
8.1 Power Redundancy
Microchip 's power redundancy mode is available in the PD-95xx-10GC Midspan series. This mode enables internal
power supply backup for two Midspans connected to each other. This mode provides seamless failover between two
Midspans. If one of the two Midspans' internal power supplies fails, failure is detected automatically and power supply
is provided to the other Midspan. Uptime of both Midspans is guaranteed to continue and all active ports continue to
operate without any effect on connected powered devices.
Power redundancy mode is available in the following midspans:
• PD-9524-10GC/AC
• PD-9512-10GC/AC
Note: While using the power redundancy option, connect only the units that share the same power supply:
• PD-9524-10GC/AC (950W)
• PD-9512-10GC/AC (950W)
WARNING
While connecting the power redundancy connectors, make sure that the AC power in both the Midspans is
disconnected from the AC mains.
8.2 Power Backup
If one of the Midspans' power supplies fails, the unit maintains full functionality by using an optional backup power
supply.

8.3 Connectors
Power backup and power redundancy connectors are located on the back panel of the Midspan.
PD-9524-10GC and PD-9512-10GC power backup and power redundancy have two connectors (see the following
figure):
• Power backup and power redundancy control signal connector, COM D-Sub: 15 pins, 3 rows female connector.
• DC voltage terminal block connector has two positive (+) terminals and two negative (-) terminals.

WARNING
Before connecting one Midspan to another, disconnect both Midspans from the AC mains.
Implement the Power Backup and Power Redundancy modes by using the cable kit that includes a DC Cable and a
signal COM.
To connect the connectors:
1. Verify that the Midspans are mounted securely on the rack.
2. Verify that the Midspans are not connected to the AC mains.
3. Connect the DC cable; two red wires (+), two black wires (-), and one yellow/green wire, as shown in the
following figure.
4. Connect the COM cable.
5. Connect the Midspans to an AC outlet.
6. Verify that the power indicator LED is ON (Green LED).
Note: While connecting a midspan to midspan, connect the earth ground cable between both units Earth Ground
connection.
