The Recovery switch is used to recover the unit from configuration errors or software image
corruption. To put a PTP 600 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
20 seconds after the power has been applied. Full instruction on the recovery mode can be
found in Section
969H9 “970HRecovery Mode”.
A simple reboot can be performed by removing and re-applying the mains power to the PTP
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 600 Series Bridge from an external DC source or to
provide a level of power supply redundancy, as shown in Section
971H1.3.3 “972HRedundancy and
Alternate Powering Configurations”.
WARNING When using alternate 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, and
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 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
973H1.3.4 “974HRemote LEDs and
Recovery Switch”
The input supply range for the 600 Series PIDU Plus is 100V-240V AC, 47-63Hz. Mains
connection to the PIDU Plus is made using a standard “figure of eight” mains lead as shown
in
975HFigure 6.
