To remove an existing blade from the ULTRIX-FR12 chassis
1. Power down the ULTRIX-FR12 and disconnect it from mains power.
2. Ensure all cabling is removed from the ports on the I/O Blade.
3. Disengage the retaining screws on either end of the I/O Blade. Refer to Figure 8.

We strongly recommend to disengage each screw until its head is approximately 0.25" away from
the faceplate. Do not fully extract the screws from the chassis.
