For optimum router performance, verify the condition of the cables that connect to the MPCs or MICs.
Action
On a regular basis:
Use an upper cable manager and a lower cable manager (shown in
cables and prevent cables from dislodging or developing stress points.

LC 10 11 12 13 14 15 16
NOTE: The MX2020 supports both standard and extended upper and lower cable
management.
Place excess cable out of the way in the upper and lower cable managers. Do not allow fastened loops
of cable to dangle from the connector or cable manager because this stresses the cable at the fastening
point. Putting fasteners on the loops helps to maintain their shape.
Keep the cable connections clean and free of dust and other particles, which can cause drops in the
received power level. Always inspect cables and clean them if necessary before connecting an interface.
Label both ends of the cables to identify them.
