Installing a Bottom Fan Tray and Front Panel Display in a QFX3008-I Interconnect Device
A QFX3008-I Interconnect device bottom fan tray and front panel display is field-replaceable and is hot-removable and hot-insertable; you can remove and replace the fan tray while the device is running without turning off power to the device or disrupting device functions. The rest of this topic uses bottom fan tray to mean bottom fan tray and front panel display.
The bottom fan tray installs horizontally as part of the front panel display located directly below the front card cage. A handle on the bottom fan tray faceplate facilitates handling of the fan tray. There is a captive screw at the top of the bottom fan tray to secure the fan tray in the chassis.
Before you install a bottom fan tray, ensure that you understand how to prevent ESD damage. See Prevention of Electrostatic Discharge Damage.
Ensure that you have the following parts and tools available to install a bottom fan tray in a QFX3008-I Interconnect device:
Electrostatic discharge (ESD) grounding strap
The fan trays can be removed and replaced while the QFX3008-I Interconnect device is operating. However, you must replace the fan tray within 2 minutes of removing the fan tray to prevent overheating of the chassis.
