Installing the MX2020 Standard EMI Covers
The upper and lower MPCs require an EMI cover to reduce the risk of radio frequency interference
disturbance that affects an electrical circuit due to electromagnetic interference emitted from an external
source. The two EMI covers are designed to reduce the electromagnetic interference (EMI) to comply with
the Federal Communications Commission (FCC) requirements.
To install the standard electromagnetic interference (EMI) card cage cover—MX2000-EMI-COVER-S (see
Figure 257 on page 595).
1. Align the four captive screws on either side of the EMI cover with the chassis front-mounting flanges
on the outside of the card cage.
2. Adjust the EMI cover until the four captive screws align with the holes in the front-mounting flanges.
3. Tighten the four captive screws to secure the EMI cover in place.
