Keying
Bands
Follow these procedures to install the module:
1.
Turn I/O chassis power off. (This refers to the power supply that
connects to the I/O chassis at its backplane.
CAUTION: To avoid module damage, always be certain that
power to the I/O chassis is off before insertion or removal of the
KA2.
2.
Insert the keying bands, as described in section titled “Keying.”
3.
Insert the module into its designated slot. Plastic tracks on the top
and bottom of the slot guide the module into position. Do not force
the module into its backplane connectors. Rather, apply a firm, even
pressure to seat the module in its slot.
4.
Snap the plastic chassis latch over the module. This secures the
module firmly in the I/O chassis.
