2. Installation

Before installing the EXM-31, unpack and inspect it for shipping damage.

DO NOT REMOVE THE MODULE FROM ITS ANTI

-

STATIC BAG

UNLESS YOU ARE IN A STATIC

-

FREE ENVIRONMENT

.

THE EXM

-

31

,

LIKE MOST OTHER ELECTRONIC DEVICES

,

IS SUSCEPTIBLE TO ESD

DAMAGE

.

ESD DAMAGE IS NOT ALWAYS IMMEDIATELY OBVIOUS

,

IN THAT IT CAN CAUSE A PARTIAL BREAKDOWN IN SEMICON

-

DUCTOR DEVICES THAT MIGHT NOT IMMEDIATELY RESULT IN A

FAILURE

.

ENSURE THAT THE INSTALLATION PROCESS AS DESCRIBED HEREIN

IS ALSO PERFORMED IN A STATIC

-

FREE ENVIRONMENT

.

Insertion in an EXM Carrier

Insertion of the EXM-31 into an EXM carrier is straightforward. Remove a blank
EXM panel from the carrier (by unscrewing the thumbscrews) and insert the
EXM-31 into the card guides. Firmly press the EXM-31 front panel to ensure that the
module is properly seated in the subplane and secure it with the thumbscrews. DO
NOT OVERTIGHTEN.

MAKE SURE THAT POWER TO YOUR SYSTEM IS OFF

.

THIS EXM IS

NOT DESIGNED TO BE INSERTED OR REMOVED FROM A LIVE

SYSTEM

.

WHEN INSERTING THE EXM

,

AVOID TOUCHING THE CIRCUIT

BOARD

,

AND MAKE SURE THE ENVIRONMENT IS STATIC

-

FREE

.

INSERT IT WITH ADEQUATE CONTINUOUS FORCE RATHER THAN

TAPPING OR HAMMERING ON IT

.
