Overview
Installing/Removing the Power Supply Unit (PSU)
CAUTION:
During installation, the module connector must align evenly with the
connector inside the module slot. Misalignment may cause the connector
pins to bend.
Modules contain static-sensitive devices. Always follow proper
electrostatic discharge (ESD) handling procedures (wristband with ground
strap and ESD mat) when installing modules in the housing. Follow
Electronic Industries Association (EIA) standard EIA-625.
The following illustration shows the location of PSU 1 and PSU 2.
The following illustration shows the PSU installed.
To Install the PSU
1 Loosen the thumbscrew and pull back from the face of the PSU.
2 Slide the PSU into the appropriate slot as shown above.
3 Push the PSU in carefully, making sure the latch fits into the holes of the
flange on the right side of the unit. This properly seats the PSU.
4 Tighten the thumb screw.
5 Connect the power cord.

Overview
To Remove a PSU
1 Remove the power cord from the PSU.
2 Unscrew the thumb screw.
3 Pull the latch and disengage from the flange.
4 Firmly pull and remove the PSU.
Important:
If only one PSU is installed, it is recommended that it be installed in slot PSU
2. A power supply cover plate (part number 4034071) should be installed in
slot PSU 1 for proper cooling.

Overview
Installing/Removing the QAM Card
The housing contains 6 hot-pluggable QAM Cards. These cards occupy slots 1-6 of
the housing. The following illustration shows the 6 QAM card slots in the
housing.
Important:
QAM cover plates (part number 4034070) must be installed in unpopulated
card slots for proper cooling.

Overview
To Install the QAM Card
Note: When a QAM Card is installed in the chassis and connected to ground
via the power cord or via an earth bonding wire, a wristband with ground
strap should be connected to the ESD socket of the chassis. See illustration
below for location of ESD socket.
1 Slide the card in the card guides slot as shown in the illustration.
2 Push the card in carefully making sure the QAM Card aligns with the system
controller connector.
Note: After the QAM Card is inserted, the card loads settings from the system
controller board and immediately starts running.
3 Tighten the QAM Card screws.
To Remove a QAM Card
Important: It is recommended that the user disable the QAM Card on the GUI,
(turn port control off) to prevent unintended service glitches on other channels.
1 Loosen the QAM Card screws.
2 Pull the QAM Card by its handle and gently remove from the housing.

Overview
Installing/Removing SFP Modules
The housing has 4 ports that can be configured with electrical or optical small
form-factor pluggable (SFP) modules. The SFP transceivers have three different
types of latching devices used to secure and detach the SFP module from a
Gigabit Ethernet port:
The Tab SFP transceiver (a)
The Button SFP transceiver (b)
The Cam Latch SFP transceiver (c)

WARNING:
Invisible laser radiation may be emitted from disconnected optical fibers or
connectors. Do not stare into beams or view directly with optical instruments.
Notes:
When the cables are extracted from the SFP transceiver, insert a clean rubber
dust plug into the SFP transceiver to protect the transceiver.
Clean the optic surface of the fiber cables before inserting into an optical SFP
transceiver.
To Install an SFP Module
1 Slide the SFP module into the housing located on the back of the RF Gateway
1.
Note:
Before inserting a Cam Latch SFP module, close the latch as shown below.
2 Gently pull on the SFP module to make sure the module is locked in place.

Overview
To Remove an SFP Module
1 Unplug the optical fiber or electrical cable from the SFP module.
2 Remove the SFP module according to the instructions below.
To remove a Tab SFP module, pull the tab gently until the module disengages
from the port. Pull the SFP module out.
To remove a Button SFP module, gently press the actuator/button on the front
of the module until it clicks and the latch mechanism activates, releasing the
module from the port.
To remove a Cam latch SFP module, remove the rubber dust plug from the
module if present. Open the latch on the module and then pull the module
out.
Note: To protect the module, it is recommended that you insert a clean rubber
dust plug.
