Juniper Networks G10 CMTS manual Install a Docsis Module

Install a DOCSIS Module

Install a DOCSIS Module			•
			•
The G10 CMTS chassis accommodates a total of eight DOCSIS Modules. The chassis is not			•
shipped from the factory with any DOCSIS Modules installed into any card cage slots. All			•
DOCSIS Modules that you order are packaged separately and must be installed at the			•
headend after the G10 CMTS has been rack mounted. The card cage is shipped from the			•
factory with seven air management modules installed in front slots that do not contain			•
DOCSIS Modules, and seven air management panels into rear slots that do not contain HFC			•
Connector Modules or SIMs. These air management modules and panels act as baffles that			•
prevent air from flowing upward through empty space or out of the chassis, and redirect the			•
air flow through slots that contain active modules. A single card cage slot (front and back) is			•
intentionally left empty when shipped from the factory because at least one DOCSIS Modules			•
and one HFC Connector Module or SIM must be installed in the system.			•
			•
DOCSIS Modules are installed in the front of the G10 CMTS chassis in card cage slots 1			•
through 4 (for domain A) and slots 10 through 13 (for domain B). HFC Connector Modules			•
and SIMs are installed in the rear of the G10 CMTS chassis in card cage slots 1 through 4 (for			•
domain A) and slots 10 through 13 (for domain B). See Figure 10 on page 25 for an			•
illustration of the chassis domains.			•
			•
To assist with the installation, the top of the air intake faceplate, the bottom of the power			•
supply faceplate, and the top of the rear fan tray are labeled with the slot numbers.			•
			•
To install a DOCSIS Module, follow this procedure:			•
			•
1. If applicable, remove the air management module from the slot. Loosen the two retainer			•
	screws, then press upward and downward on the ejector releases (action #1 in Figure 31		•
	on page 104). Simultaneously pull the ejectors away from the module faceplate (action		•
	#2 in Figure 31), and slowly slide the module out of its slot until it is fully removed from		•
	the system (action #3 in Figure 31).		•
			•
2. Remove the module from its anti-static bag, being careful to avoid directly touching any			•
	component on the module. We recommend that you handle the module by by its card		•
	edges or ejectors.		•
			•
			•
		If any G10 CMTS module has been removed from its
			•
		anti-static bag and must be temporarily put aside prior to	•
		its installation, you should replace the module into the	•
		anti-static bag or on top of an anti-static mat that is	•
		properly grounded.	•
			•
3.	If the upper or lower ejector of the module is locked in the vertical 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 front 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 32 on page 105). 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 vertical and		•

each ejector clicks into position. The module faceplate should be flush with the faceplate	•
	•
of any other adjacent module.
