9.2.3. Powering the IFL
•
Transmitter power requirement: +15VDC @ 300 mA
•
Receiver power requirement: +15VDC @ 250 mA
•
The Standalone Transmitter/Receiver can be powered by a
Foxcom-supplied external DC power supply.
•
The Rackmount Transmitters/Receivers are plugged into the
7100M rackmount chassis. The chassis can accept and power up
to six units.
Note
At temperatures below 10
°
C, the Transmitter’s internal heater will
require an additional 100 mA. The Transmitter’s total power
requirement will then be 400 mA.
CAUTION
Ensure that there is a good airflow around the chassis rackmount.
There should be the space of a rackmount between chassis.
7100M Chassis
The 7100M Chassis provides power to the plug in units. The power
supply is a linear unregulated type. Each plug-in regulates its own
voltage. The power supply provides:
•
15 to 18 VDC (unregulated) @ 2.2 amps power
•
AC input @ 110/220 VAC (user selected)
•
Units can be plugged in “hot standby”
•
An internal 5 amp fuse (refer to Table 18, page 70 for the fuse
part numbers)
Note
By default the power supply is set to 220V (0.5A).
7000S (Optional) Hot Standby Power Supply
For applications demanding the utmost in reliability and uptime, the
7000S standby power supply can be optionally plugged in to the
standard chassis. The 7000S features hot swapping - supplies may
be installed and removed even during operation. Each power supply
is fully redundant and can power a completely loaded chassis on its
own should its "partner" fail. During normal operation the two units
share the load by means of current steering diodes located on the
rear panell.
