The Recovery switch is used to recover the unit from configuration errors or software image
corruption. To put a PTP 500 Series Bridge 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 9 "Recovery Mode".
A simple reboot can be performed by removing and re-applying the mains power to the PTP
300/500/600 Series Bridge PIDU Plus.
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 500 Series Bridge from an external DC source or to
provide a level of power supply redundancy, as shown in Section 3.3.3 "Redundancy and
Alternative Powering Configurations".
WARNING When using alternative DC supplies the supply MUST comply with the following
requirements:
•
The voltage and polarity is correct and is applied to the correct terminals in the PIDU Plus
•
The power source is rated as SELV
•
The power source is rated to supply at least 1A continuously
•
The power source cannot provide more than the Energy Hazard Limit as defined by
IEC/EN/UL6090, Clause 2.5, Limited Power (The Energy Hazard Limit is 240VA)
Also on the left hand side of the PTP 300/500/600 Series Bridge 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 3.3.4 "Remote LEDs
and Recovery Switch".
