Installing a QFX10000 Line Card
QFX10000 line cards are field-replaceable units (FRUs) that can be installed in any of 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.
Before you install a line card in the switch chassis:
• Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD)
damage. See
Prevention of Electrostatic Discharge Damage
.
• Ensure that you know how to handle and store the line card. See
Handling and Storing QFX10000
Line Cards, RCBs, and SIBs
.
• Inspect the connector edge of the line card for physical damage. Installing a damaged line card might
damage the switch.
• Ensure that the switch has sufficient power to power the line card while maintaining its
N+1 power
redundancy. To determine whether the switch has enough power available for the line card, use the
show chassis power-budget-statistics
command. See also
Power Requirements for QFX10000
Components .
• Ensure that you have the following parts and tools available to install a line card in the switch:
• ESD grounding strap
• Phillips (+) screwdriver, number 2
To install a line card in the switch chassis:
1. Attach the ESD grounding strap to your bare wrist and connect the strap to the ESD point on the
switch chassis. The ESD point is located above the status LED panel on the front of the switch
chassis. See
Figure 185 on page 334 and Figure 186 on page 335 .
