QFX10000 line cards are field-replaceable units (FRUs) that can be installed in the line
card slots on the front of the chassis. The line cards are hot-insertable and hot-removable:
you can remove and replace them without powering off the switch or disrupting switch
functions. However, we recommend that you take them offline before removing them.
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" on page
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" on page
Ensure that you know how to handle and store the line card. See
Line Cards, Routing and Control Boards, and Switch Interface Boards" on page
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:
Place the antistatic bag or antistatic mat on a flat, stable surface.
