removable but it does extract the blade. Refer to Figure 8 for the bolt location on the rear

Installing an ULTRIX-MODX-IO Blade into the ULTRIX-FR12 Chassis

devices. Avoid handling circuit blades in high static environments such as carpeted areas and when
synthetic fiber clothing is worn. Always exercise proper grounding precautions when working on circuit
blades and related equipment.
To install an ULTRIX-MODX-IO blade into the ULTRIX-FR12 chassis
1. Using the card guides inside the chassis, gently slide the ULTRIX-MODX-IO blade into the chassis
while lifting up slightly to take the weight.
 Ensure the blade is oriented with the ULTRIX-MODX-IO logo on the bottom (the side nearest to
the slot silk-screen numbering on the chassis). Refer to the other blades installed in the chassis
for orientation.
2. Gently slide the blade in until you feel it start to resist as the edge connectors begin to mate.
This will occur approximately 1/8" (3mm) before the blade is fully seated. At this stage, the
Middle Retaining Bolt should be used to pull the blade into its final mated position.
3. Using a 3/16" socket, fully tighten the Middle Retaining Bolt. This bolt secures the blade to the
chassis from the interior, ensuring proper contacts between the blade and the router
backplane.
Caution
— You must first fully tighten the Middle Retaining Bolt before tightening the screws on the
ULTRIX-MODX-IO. Not doing so will damage the blade, the connectors on the backplane, or both.
