The power indicator is illuminated when the Canopy 150/300 Mb BH PIDU is receiving mains
power.
The Ethernet indicator normally illuminates when the Ethernet link is working; Flashing when
there is Ethernet activity; the fact that it lights also indicates that the ODU is powered. At
power up the LED will flash 10 times to indicate that a correct start up sequence has
occurred. See Section 10 “Fault Finding” for further fault finding information.
At the bottom of the Canopy 150/300 Mb BH PIDU is an entry point for the Canopy 150/300
Mb BH PIDU to ODU cable, the 1000BaseT 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 a Canopy 150/300 Mb BH unit into recovery mode the recovery switch
should be depressed then the power applied. The recovery switch should be kept depressed
for between 10 to 20 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
Canopy 150/300 PIDU.
On the left hand side of the 150/300 PIDU -48V DC input and output connections can be
found. These are used to power the 150/300 Mb BH from an external DC source or to provide
a level of power supply redundancy as shown in Section 3.2.3 “Redundancy 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 150/300
PIDU
•
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 150/300 PIDU 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”
The input supply range for the 150/300 PIDU is 100V-240V AC, 47-63Hz. Mains connection
to the 150/300 PIDU is made using a standard “figure of eight” AC mains plug and/or -48 V
DC (cable size 2.5mm 2 stranded or 14 AWG stranded) lead as shown in Figure 5 .
