If you have the optional line-card cable management system, it is not necessary to remove the cable
management system before removing the line card.
Before you remove a line card from the switch chassis:
• Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD)
damage. See
Prevention of Electrostatic Discharge Damage
.
• If there are any optical cables, (including transceivers, direct-attach copper (DAC), or DAC break-out)
installed in the line card), remove them before you remove the line card. See
Removing a Transceiver
.
• Ensure that you know how to handle and store the line card. See
Unpacking QFX10000 Line Cards,
Routing and Control Boards, and Switch Interface Boards
.
Ensure that you have the following parts and tools available to remove a line card from a QFX10000
chassis:
• ESD grounding strap
• An electrostatic bag or an antistatic mat
NOTE: Placing a line card in an electrostatic bag might require a second person to assist with
sliding the line card into the bag.
• Replacement line card or a cover for the empty slot
To remove a line card from a QFX10000 switch chassis:
1. Place the antistatic bag or antistatic mat on a flat, stable surface.
2. Attach the ESD grounding strap to your bare wrist and connect the strap to the ESD point above the
status LEDs on the switch chassis (see Figure 181 on page 331 ).
