Installing the T640 Mounting Hardware for a Four-Post Rack or Cabinet
To prepare to install the T640 router into a four-post rack or cabinet:
•
Install cage nuts, if needed.
•
Install the large mounting shelf and the spacer bars on the front rack rail.
•
Install the small mounting shelf on the rear rack rail.
•
Remove the center-mounting brackets from the chassis.
The mounting brackets and flanges have holes for rack-mounting screws, spaced at
5.25 in. (13.34 cm).
Table 87 on page 159 specifies the holes in which you insert mounting screws (an X
indicates a mounting hole location), and cage nuts if needed. The hole distances are
relative to one of the standard U divisions on the rack. The bottom of all mounting shelves
is at 0.04 in. (0.02 U) above a U division.
