Remove an active Fail-Open module from the chassis

Prev Next

Prerequisite:

You must make sure the Fail-Open module is fully powered off before you attempt to remove it from the chassis.

Note

Trellix recommends you power off the Fail-Open module before removing it from its slot. The module can be individually powered down by pressing the corresponding M1 M2 or M3 button for at least 4 seconds. If you replace a module with the same type, the replaced module will be active after insertion and does not require a reboot of the system.

Follow the steps in this section to power off and remove the Fail-Open module.

Steps:

  1. Power off the Fail-Open module using the web interface or CLI command prompt.

  2. When the Fail-Open module is powered off, remove the captive screws and slide it out of the chassis.
