Switch Card Assembly
Attention:
v The switch card assembly is electrostatic-discharge (ESD) sensitive. Use the tools
and procedures defined by your organization to protect such parts. See also
“Electrostatic Discharge” on page xi.
v If the switch card assembly has been removed, and the 2104 receives a ‘Reset’
signal, or is switch off then on, the 2104 uses the default logical switch settings (see
“Switch Card Assembly Switches” on page 9).
Notes:
1. Unless you have a particular reason to do so, do not switch off the using system or
the 2104 when removing or installing the switch card assembly.
2. The diagrams in these instructions show a 2104 Model DU3. The procedure for a
2104 Model TU3 is the same, except that everything is turned through 90 degrees.
