Procedure
Step 1 Place the right front air deflector flush against the right side of the chassis as shown in Diagram 1 of Figure
127: Mounting the Air Deflectors (Front-to-Back) on the ONS 15454 M2 Shelf for ETSI Rack Configuration,
on page 207.
Step 2 Align the screw holes on the right front air deflector with the screw holes on right side of the chassis.
Step 3 Insert the screws and tighten them to a torque value of 11.5 in-lb (1.3 N-m). See Diagram 2 of Figure 127:
Mounting the Air Deflectors (Front-to-Back) on the ONS 15454 M2 Shelf for ETSI Rack Configuration, on
page 207.
Step 4 Place the left back air deflector flush against the chassis as shown in Diagram 1 of Figure 127: Mounting the
Air Deflectors (Front-to-Back) on the ONS 15454 M2 Shelf for ETSI Rack Configuration, on page 207.
If the 100G-LC-C, 10x10G-LC, or CFP-LC cards are to be installed in the ONS 15454 M2 shelf,
do not mount the left back deflector (exhaust air deflector). Use the standard brackets directly to
mount the ONS 15454 M2 shelf.
Note
Step 5 Align the screw holes on the left back air deflector with the screw holes on the chassis.
Step 6 Insert the screws and tighten them to a torque value of 11.5 in-lb (1.3 N-m). See Diagram 2 of Figure 127:
Mounting the Air Deflectors (Front-to-Back) on the ONS 15454 M2 Shelf for ETSI Rack Configuration, on
page 207.
Step 7 Place the air deflector covers on the front and rear ends of the chassis as shown in Diagram 3 of Figure 127:
Mounting the Air Deflectors (Front-to-Back) on the ONS 15454 M2 Shelf for ETSI Rack Configuration, on
page 207.
Step 8 Align the screw holes on the air deflector covers with the screw holes on the chassis.
Step 9 Insert the screws and tighten them to a torque value of 11.5 in-lb (1.3 N-m). See Diagram 4 of Figure 127:
Mounting the Air Deflectors (Front-to-Back) on the ONS 15454 M2 Shelf for ETSI Rack Configuration, on
page 207.
Step 10 Place the mounting bracket flush in the front position (see Diagram 1 of Figure 128: Mounting the Brackets
with Air Deflectors (Front-to-Back) on the ONS 15454 M2 Shelf for ETSI Rack Configuration, on page 207)
or in the middle position (see Diagram 3 of Figure 128: Mounting the Brackets with Air Deflectors
(Front-to-Back) on the ONS 15454 M2 Shelf for ETSI Rack Configuration, on page 207) against the right side
of the chassis.
Step 11 Align the screw holes on the 23-inch mounting bracket with the screw holes on the right side of the chassis.
Step 12 Insert the screws and tighten them to a torque value of 11.5 in-lb (1.3 N-m).
Step 13 Place the mounting bracket flush in the front position (see Diagram 1 of Figure 128: Mounting the Brackets
with Air Deflectors (Front-to-Back) on the ONS 15454 M2 Shelf for ETSI Rack Configuration, on page 207)
or in the middle position (see Diagram 3 of Figure 128: Mounting the Brackets with Air Deflectors
(Front-to-Back) on the ONS 15454 M2 Shelf for ETSI Rack Configuration, on page 207) against the left side
of the chassis.
Step 14 Align the screw holes on the 23-inch mounting bracket with the screw holes on the left side of the chassis.
Step 15 Insert the screws and tighten them to a torque value of 11.5 in-lb (1.3 N-m).
