Juniper Networks G10 CMTS manual 106

Install an HFC Connector Module or SIM

•	3. If the upper or lower ejector of the module is locked in the horizontal position, press
•	upward or downward on the ejector release while simultaneously pulling the ejector
•	away from the module faceplate. Each ejector should rest at approximately 45° away
•	from its locked position.
•
•	4. Each card cage slot in the rear of the chassis has an upper and lower card guide. Align
•	the printed circuit board of the module with the card guides and slowly slide the module
•	into the slot until it comes to a stop (action #1 in Figure 33 on page 107). The inside tabs
•	(tabs closest to midplane) of the upper and lower ejectors should be resting directly
•	under and over the module ejector rail.
•
•	5. Simultaneously push the ejectors toward the module faceplate until they are horizontal
•	and each ejector clicks into position. The module faceplate should be flush with the
•	faceplate of any other adjacent module.
•
•
		When you install a rear chassis module, apply more
•
		pressure to the upper ejector than to the lower ejector. This
•
		ensures the module connectors on the top of the card edge
•
		are properly aligned with the midplane connectors. The
•
		bottom edge has no connectors, so you do not need to
•
		press the rear ejector as firmly.
•
•
•	6. Tighten the two retainer screws by applying 3 in-lb of torque to each screw.
