Replacing the MX2020 Cable Managers

 

The MX2020 router consists of an upper, middle card-cage, lower, and DC cable management system used for routing and securing cables away from system components. There are two types of cable management systems: standard and extended. The following instructions represent both.

Note

The middle card-cage cable manager is permanently installed on the MX2020 system chassis, and cannot be removed.

Removing the MX2020 Upper Cable Manager

Note

To accommodate additional clearance, you may order an extended upper cable manager from Juniper Networks.

To remove the upper cable manager (see Figure 1):

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  2. Loosen the two captive screws on the upper cable manager cover, and remove it.
  3. Using a Phillips (+) screwdriver (number 1 or 2), loosen the mounting screws on the upper cable manager.
  4. Grasp the upper cable manager, and pull it straight out from the studs on the front of the chassis.
