Installing a Side Fan Tray in a QFX3008-I Interconnect Device
A QFX3008-I Interconnect device has eight field-replaceable side fan trays. All eight side
fan trays are hot-removable and hot-insertable field-replaceable units (FRUs); you can
remove and replace the fan tray while the device is running without turning off power to
the device or disrupting device functions.
Four fan trays install vertically on the left front of the chassis and four on the right front
of the chassis. Handles and captive screws on the two cover panels on each side of the
chassis facilitate handling and securing of the fan trays in the chassis.
Before you begin to install a fan tray, ensure that you understand how to prevent ESD
damage. See “Prevention of Electrostatic Discharge Damage” on page 192.
Ensure that you have the following parts and tools available to install a fan tray in a
QFX3008-I Interconnect device:
•
Electrostatic discharge (ESD) grounding strap
•
Replacement fan tray
