Installing Slide-In Cards
CAUTION: Wear a grounding device and observe electrostatic
discharge precautions when installing Slide-In Cards. Failure to
observe this caution could result in circuit board failure.
NOTE: Slide-in Cards can be hot-swapped.
To install a Slide-In Card:
1. Determine if the Slide-In Cards has an SQE switch and, if so,
verify that the SQE switch is in the OFF position:
NOTE: SQE switches must be set to the following OFF
positions:
•
UTP/STP card
TOWARD 20-pin edge connector
•
Thinnet card
TOWARD 20-pin edge connector
•
AUI-DCE
AWAY FROM 20-pin edge connector
•
AUI-DTE card
Not Applicable
•
Fiber Optic card
TOWARD 20-pin edge connector
•
Redundant Fiber Optic
SQE jumper setting on board should be
labeled; if not, holding card with 20-pin edge
connector at top, jumper two leftmost pins.
•
Bridge
Not Applicable
2. With the Slide-In Card components facing up, carefully guide
the Slide-In Card along the card guides until the Slide-In Card
connector meets the the Multi Media Repeater backplane.
3. Firmly push the card into the slot until the Slide-In Card
faceplate is flat against the Multi Media Repeater frame.
4. Rotate the Slide-In Card thumbscrews into the Multi Media
Repeater threaded holes.

Connecting Cable to SIC and/or AUI Connector
Connections between installed Multi Media Repeater SICs or between
a Multi Media Repeater SIC and/or terminal device include:
•
Female AUI Connector/10Base5
•
Male AUI Connector/PC
•
RJ Connector/10BaseT
•
BNC Connector/10Base2
•
ST Connector/Fiber Optic
BNC Connector/10Base2 Connection
The thinnet coaxial card (E-CX-SIC) provides a BNC connector to
10Base2.
NOTE: Verify that coax cables on Multi Media Repeater are terminated
properly at both ends. (In a coax thinnet installation, the first and last
device in a daisy-chain must be
terminated with a 50 ohm
terminator.)
Additionally, the 10Base2
segment must be grounded to
“earth ground”.
