Installation
Installation
The 8943FC model consists of a front and rear module set that can only be
installed in a GeckoFlex frame. Two fiber optic dual transmitter SFP device
kits, shipped separately, must also be installed for full functionality of the
module.
Installation of the 8943FC module set is a process of:
1. Placing the 8943FC-R rear module in a rear frame slot,
2. Installing the fiber optic SFP devices on the front module,
3. Placing the front module in the corresponding front slot,
4. Cabling the signal ports, and
5. Setting module parameters with on-board switches or with the web
browser interface.
All GeckoFlex front and rear modules can be inserted and removed from
an GeckoFlex frame with power on.
Note Modules and SFP devices are sensitive to static damage, use standard anti-
static precautions when handling components.
Module Placement in the GeckoFlex Frame
There are ten front and rear cell locations in the 2 RU GeckoFlex frame
(Figure 1) to accommodate either audio, analog and digital video modules.
Figure 1. GeckoFlex Frame

12 8943FC — Instruction Manual
Installation
Module Installation Precautions
Please read and follow the precautions listed below before installing the
front and rear modules and any optional fiber optic SFP devices:
• Use standard anti-static procedures during installation. As modules
can be installed or removed when the GeckoFlex frame is powered up,
before removing the cover, please use an anti-static bracelet tied to a
metal part of the frame.
• Install the rear module first, then install the option fiber optic SFP
devices on the front module, then install the front module.
• When installing or removing a rear module, loosen or tighten the
screws holding the retainer clips to the frame manually with the
retainer clip tool provided inside the front cover of the frame or use a
2 mm (5/64”) hex screwdriver. Please do not use an electric screw-
driver.
Note On newer 751- version GeckoFlex frames, a Rear Retainer Clip removal tool
and 2 extra retainer clips and screws for installing them are provided on the
inside of the frame cover.
• Make every effort to leave the screws holding the retainer clips in place
(do not remove them completely). They are very small and can easily
drop into other equipment causing a shorting hazard. (Two turns of the
screw should be enough to loosen the screws, 3 turns or more will
remove it.)
• When installing a rear module, tighten the screws on the retainer clips
just until snug. Do not apply more force than is necessary to seat the
rear module. Refer to the Mechanical specifications given in Table 6 on
page 53.
• If using a fiber optic SFP device on the fiber-ready front module, handle
it carefully, use anti-static precautions, and read the Installation on
page 11 before cabling.

8943FC — Instruction Manual 13
Installation
Rear Module Installation
To install the rear module, refer to Figure 2 and the instructions below:
1. To remove a blank rear adapter cover (or a rear module already
present), manually loosen the two screws holding each retainer clip on
the rear adapter cover or rear module to the frame with the retainer clip
tool provided inside the front cover of the frame (newer model frames
only) or a 2 mm (5/64”) hex screwdriver. Do not remove the screws.
Note To remove a rear module already installed, follow the same steps. It is helpful
to first remove the front module so the rear can be pulled out more easily.
2. After loosening the retainer clip screws, pull up on each retainer and
completely remove it, leaving the screws in place.
3. Remove the blank rear adapter cover by inserting needlenose pliers
into the slots in the blank cover and pulling it off.
4. Insert the rear module into the empty slot, guiding it carefully.
5. Replace each retainer clip over the two screws on both sides of the
module and push down to seat the retainer clip.
6. Tighten the two screws on each retainer clip just until they come into
contract with the retainer clip then tighten about a 1/4 turn more
(maximum torque is 4-5 inch-lb/0.45-0.6Nm). Do not force or torque
the screws too tightly. The clips should not bend or be bowed.
Note All unused rear slots in a GeckoFlex frame should have a blank rear adapter
cover installed.

SFP Device Installation
Two optional dual channel CWDM receiver SFP devices can be installed on
an 8943FC module. Both are installed on the front of the module circuit
board. The type of SFP device depends on the application of the module
and the 8939FCA or 8939FCB module it will be feeding. Refer to Table 1 on
page 10.
The optional strap-mount SFP Fiber Optic kit (Figure 3) for GeckoFlex
fiber-ready modules includes:
• One Strap Mount Fiber Optic SFP Device (labeled for type)
• Mounting bracket for SFP device installation
• Fiber cable assembly for connecting SFP device to front module rear
connector
Figure 3. SFP Device Kit
Fiber Optic Cleaning Requirement
Before making any fiber optic cable mating connections to the SFP device
or cabling and after every de-mating cycle, use an industry standard fiber
optic cleaning kit, including oil-free compressed air, to clean the fiber con-
nectors and the connectorized fiber end faces. This helps ensure optimum
performance of the fiber optic interface. Industry standard fiber optic
cleaning kits can be purchased on the web and in electronics stores.
