second hole over the ESD grounding point. Fasten the seal and flange to the rack using the
Phillips screwdriver to tighten the mounting screw.
c. Loosen the mounting screws next to the line card along one side of the chassis.
d. Position the keyhole slots of one of the long cable seals over the mounting screws. The long cable
seals are not interchangeable; there is a right seal and a left seal. Install the seals so that the
keyhole slots are on the inside, next to the line card. See
Figure 49: Install the Cable Seals
e. Slide the keyhole slot down behind the mounting screws and align the cable seal with the chassis.
Tighten the mounting screw with a Phillips screwdriver.
f. Repeat Step
through Step
for the remaining cable seal.
3. Install optics and attach the front door.
a. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the
other end of the strap to the ESD point on the front of the chassis. See
b. Insert all optics and thread the cables through the cable seals.
c. Lift the front door, and align the captive screws in the door with holes in the chassis flange below
the cable seals. Fasten the door to the chassis and rack, and hand tighten.
