2.7.2 ODU, LAN and Recovery

At the bottom of the PIDU Plus is an entry point for the PIDU Plus to ODU cable, the
100BaseT Ethernet network port and the Recovery switch.
The Recovery switch is used to recover the unit from configuration errors or software image
corruption. To put an ODU into recovery mode, the Recovery switch should be pressed, then
the power applied. The Recovery switch should be kept pressed for at least 30 seconds after
the power has been applied. Full instruction on the recovery mode can be found in Section 8
"Recovery Mode".
A simple reboot can be performed by removing and re-applying the mains power to the PIDU
Plus.

2.7.3 DC In and Out

On the left hand side of the PIDU Plus, 48V DC input and output connections can be found.
These are used to power the PTP 300 Series Bridge from an external DC source or to
provide a level of power supply redundancy, as shown in Section 2.8 "Redundancy and
Alternative Powering Configurations".

2.7.4 Remote Connectors and Jumpers

Also on the left hand side of the PIDU Plus, connectors and jumpers can be found that allow
the remote connection of power LED, Ethernet LED and Recovery switch. The connection
instructions can be found in Section 2.9 "Remote LEDs and Recovery Switch".
