10.5 914-X Series Electrical and Environmental Specifications
The tables below summarize the electrical power requirements and environmental specifications of standard
products. Cards can be configured and/or screened at the factory for extended performance, such as higher
operational temperatures.

* The maximum power is with a 12V input at +60
o
C.
** This power is in addition to the 914-HDE, all stacked cards and their associated power ratings must be combined
to calculate a total system power rating.
*** Higher operational temperatures are possible by using thermal management to ensure electronic parts do not
exceed a case temperature of +85
o
C.
**** 914-AX power is highly dependent on the AIB module installed.
Input amperage must not exceed 4 A, if close to 20 W is required, the power supply must use a higher nominal
voltage e.g. 12 V.
10.6 914-X Series Maintenance
The unit requires no routine maintenance or calibration for the specified performance. Maintenance of the units is
limited to cleaning the various components using the methods described below.
Dust or dirt on the cards can be blown off using compressed air. If severe contamination of the cards should occur,
they can be removed and cleaned using distilled water. Cards must be thoroughly dried before reapplying power.
In order to maintain optical performance, please refer to the following optical considerations.
Optical Considerations
1. Observe the bend radius of fiber optic cables at all times
When mounting, disassembling, or reassembling the cards in your system, ensure that no fibers are subjected
to bends in excess of those held by the natural routing of the fibers. The minimum bend radius of the fibers
should generally be no less than 25 mm, though single loops may be less than this
– as low as 15 mm –
without damaging the fibers. Keep in mind that allowable values are dependent on the type of fiber and the
environment, and cable manufacturers typically specify the minimum bend radius. Avoid even temporary
bends with a radius less than 15 mm, which may induce cracks that affect long-term reliability of the fibers. In
general, fiber jumpers and pigtails should be periodically inspected for damage, such as nicks in the jackets
or excessive bends.
2. Ensure fiber optic components are of the same type
All jumpers, cables, connectors, couplers, and Fiber Optic Rotary Joints (FORJs) used in the external optical
system connecting the remote to console multiplexer must use the same type of fiber.
