INSTALLING THE OPTION MODULE

It is 

not

 necessary to turn off the power to the TSU/HSU

when installing the option module because it is 

hot

swappable

.  The plug-on board must be attached to a hot

swappable option module if you wish to install it while the
TSU/HSU is powered on.

Placement of the Option Module

Figure 2-1 is representative of the action required for
proper placement of the option module.  Perform the
following steps to install the option module:

1.

Remove the cover plate from the TSU/HSU unit rear
panel.

2.

Slide the option module into the rear panel of the
TSU/HSU unit until it is positioned firmly against the
front of the unit.

3.. Fasten the thumbscrews at both edges of the option

module.
