68 JUNOSg 3.0 G10 CMTS Hardware Guide
During the preparation and installation of the G10 CMTS,
we strongly recommend that you adhere to the
precautions presented in this section to avoid physical
injury due to lifting, moving, or rack mounting the CMTS.
! Only trained and certified personnel should be involved in the installation of the CMTS.
! We recommend the use of a lift to install the G10 CMTS.
! Do not attempt to lift the G10 CMTS alone. If a lift is not used, we recommend at least
three installers assist with lifting the system. This includes removal from the shipping
carton, temporary or permanent placement on a flat surface, rack mounting, or lifting
for any other purpose.
! Prior to lifting and moving the G10 CMTS, ensure that the path you will be taking is
totally unobstructed.
! To avoid back injury when lifting the G10 CMTS, avoid bending your back to achieve lift
leverage. Instead, keep your back in the upright position, and bend at the knees. Also
avoid twisting your back while lifting.
! Always rack mount a system from the bottom up to maintain the lowest possible center
of gravity of the entire rack with its equipment.
! Do not install any additional modules or power supplies to the G10 CMTS prior to
mounting it in a rack. First mount the system into the rack with its original contents as
shipped, then install additional components after the G10 CMTS is securely mounted to
its rack.
! Never attempt to move the G10 CMTS while any cables or power cords are still
connected.
! Ensure that any loose articles of clothing are well clear of the fan trays prior to powering
up the G10 CMTS.
During the preparation and installation of the G10 CMTS,
we strongly recommend that you adhere to the
precautions presented in this section to avoid physical
injury due to an electrical hazard.
High levels of electrical energy are distributed across the
system midplane. Be careful not to contact the midplane
connectors, or any component connected to the midplane,
with any metallic object while hot-swapping or servicing
components installed in the system.
! We recommend at least two installers be present when connecting the G10 CMTS to its
power source.
