Installing the Lockable Front Doors on a QFX3008-I Interconnect Device

 

The lockable front doors cover the front card cage. A captive thumbscrew at the base where the doors meet secures the doors in a closed position. You can also lock these doors in the closed position to prevent cables, transceivers, or front cards from being removed. You must provide the lock. The lockable front doors are an optional field-replaceable unit (FRU), it is not required that you install them.

Before you begin, ensure that you have the following parts and tools available to install the lockable front doors on a QFX3008-I Interconnect device:

  • Electrostatic discharge (ESD) grounding strap

  • Phillips (+) screwdriver, number 1

  • Eight mounting screws—These screws are already installed on the chassis, in each corner of the top and bottom front card cage ejector lever receptacle bars.

To install the lockable front doors on a QFX3008-I Interconnect device (see Figure 1):

  1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
  2. Remove the two screws at each corner of the top and bottom front card cage ejector lever receptacle bars. The screws are located in the inset portion of the bar.
  3. Place one of the doors on the chassis, aligning the holes on its faceplate with the mounting holes on the chassis.
  4. Install the four mounting screws, tightening them by turning them clockwise using the Phillips (+) screwdriver, number 1.
  5. Repeat Step 2 through Step 4 for the other door.Note

    The doors must be in the open position to remove or install the bottom fan tray and front panel display.
