148 JUNOSg 3.0 G10 CMTS Hardware Guide
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
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.
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.
