Installing the Opacity Shield on the Cisco 7600 Series Routers
Step 8
Position the rivet sleeve over one of the square cutouts on the opacity shield. Refer to
Figure 6
for snap
rivet fastener placement. Press the rivet sleeve through the cutout, through the opacity shield material,
and through one of the chassis air vent perforations.
Note
You might need to try different cutouts to find the one cutout that aligns correctly with a chassis
air vent perforation.
Step 9
Push the rivet pin through the rivet sleeve until you hear a click.
Note
If you do not hear a click, remove and inspect the snap rivet fastener. If the rivet sleeve appears
expanded or damaged, discard the snap rivet fastener and use a new one from the extras supplied
in the bag of fasteners.
Step 10
Repeat step 8 and step 9 for the remaining three snap rivet fasteners. Refer to
Figure 6
for snap rivet
fastener placement.
Caution
Due to decreased airflow when using the opacity shield, which is required for FIPS 140-2 validation,
short-term operation as specified by GR-63-CORE at 55º C is impacted. Short-term operation
requirements will only be met at 40º C. Without the opacity shield installed, the system will meet the
short-term operations requirements at 55º C.
Caution
We recommend that you change the opacity shield every three months to prevent dust build-up and the
possibility of overheating the chassis. If the environment is especially dusty, inspect and replace the
opacity shield more often.
Note
If you need to remove the Catalyst 6509 chassis from the rack, you must first remove the opacity shield.
With the opacity shield installed, the chassis is too wide to slide out of the rack.
