•
•	This section lists the following issues associated with powering up and booting the CMTS,
•	along with procedures to resolve them:
•
•	! CMTS Is Not Powering Up on page 148
•
•	! CMTS Does Not Boot Successfully on page 148
•
•	! CMTS Powers Down on page 149

•CMTS Is Not Powering Up

•
•	If it appears that power is not being applied to the CMTS—because you do not hear or see
•
	any fans rotating, or do not see any LEDs illuminated—the cause might be one or more of
•
	the following:
•
•	! The power cords are not securely connected to the power transition modules and to
•
	their power sources.
•
•	! The power switches and the power sources are not turned on.
•
•	! The power supplies have failed. Note the status of the power supply LEDs. If the Power
•
	LED is not green or if the Fault LED is illuminated, take the appropriate actions described
•
	in Table 40 on page 124.
•
•
•	CMTS Does Not Boot Successfully
•
•	If you do not get to the login and password prompts, the CMTS did not successfully boot up.
•
	The cause might be one or more of the following:
•
•	! A new module added to the system might not be properly installed into the midplane of
•
	the chassis. See “Install the CMTS” on page 93 for more information.
•
•
•		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.
•
•	! The CMTS does not have at least one DOCSIS Module installed.
•
•	! A module is not operational. After you check that all modules are properly installed in
•
	the chassis, check their status LEDs to ensure they have powered up successfully. If you
•
	observe any of the following LED states, contact customer support:
•
•	! The Power LED of a Chassis Control Module remains red indefinitely.
•
•	! The Test LED of any DOCSIS Module remains red indefinitely.
•
•	! Any of the 1 through 6 LEDs of any DOCSIS Module is not green.
