1. CABLE AND CONNECTOR DAMAGE ON THE
LINK CARDS FOR E2 SERIES AND S3-4K
SERIES PRESENTATION SWITCHERS
1.1 General
Phenom enon
The cable connectors and Link Card connectors can be damaged when connecting Link Cards
for E2 series and S3-4K series presentation switchers. Bent tabs on the cable connectors
can damage the internal connectors of the Link Car ds.
Cause
When improperly inserted, the sheet metal on the cable can wedge into the connector,
breaking the plastic and bending the pins.
Seeimage1-1foranexampleofanundamagedcableend. Seeimage1-2foranexample
of a damaged cable e nd. The arrow in image 1-2 indicates where the shield has been bent
downwards, because of improper insertion. See image 1-3 for an example of the c able
latch hitting the connector. See image 1-4 for an example of incomplete insertion of the
cable into the Link Card connector.

the edge of the Link Card connector. The arrows labeled “2” show the holes into which the
latch should fit. See image 1-7 for an example of a properly latched cable and connector.

Image 1-4
Incomplete insertion – 5 mm
In image 1-4 about 5 mm of the end of the cable is still exposed; this is about the width of
four dimes.
It is at about the 5–mm point that the sheet metal on the cable can wedge into the con-
nector. When the cable wedges into the connector, the cable stops unless it is pushed hard
(greater than 2 pounds of force). The cable s hould slide sm
oothly, until the latches on the
cable come into contact with the connector itself, a nd the cable is in the position seen in
image 1-5 and image 1-7.
Solution
Follow the instructions in this document to help make sure that the cable is properly inserted
into the connector on each Link Card.
Scope
This procedure applies to all Link Cards on a
ll E2 series and S3-4K series presentation
switchers.
1.2 Properly connecting the Link Card cable
Connect the cable to the Link Card
1. Fully insert the cable into the connector on the Link Card.
The CXP connection is keyed. A groove on the cable-end connector guides a pin on the
Link Card connector.
(The Link Card connector shown in image 1-5 is shown as a component, not inserted on
aLinkCard.)

2. If the cable resists full insertion, pull the cable slightly back toward the release, rotate it
counterclockwise, and reinsert it.
The arrow labeled “1” in image 1-6 shows the release. The c urved ar
row shows the
counterclockwise rotation.
