JUNOSg 3.0 G10 CMTS Hardware Guide 108
Install a Chassis Control Module
The G10 CMTS chassis accommodates a maximum of two Chassis Control Modules in slots 6
and 7. To install a Chassis Control Module, follow the same procedure described in “Install a
DOCSIS Module” on page 103.
Install a Hard Disk Module
You must install a Hard Disk Module opposite each installed Chassis Control Module. To
install a Hard Disk Module, follow the same procedure described in “Install an HFC Connector
Module or SIM” on page 105.
Install a NIC Module
The G10 CMTS chassis accommodates a maximum of two NIC Modules in slots 5 and 9 for
domain A and domain B. NIC Modules are shipped from the factory with two multimode
GBIC modules installed. If you are using a different GBIC module interface, you need to
replace the multimode GBIC modules that are shipped with the NIC Module. We recommend
that you remove and install the GBIC modules while the NIC Module is installed in the
chassis.
To install a NIC Module, follow this procedure:
1. Follow the same procedure described in “Install a DOCSIS Module” on page 103. If you
will be using a GBIC module interface other than multimode, proceed to step 2.
Otherwise, you have completed the installation of the NIC Module.
2. Remove each multimode GBIC module by squeezing the metal clasps at the top and
bottom of the GBIC module towards the module and firmly pull out the module until it is
removed from its slot.
3. With the label side of the GBIC module facing the right, slide each replacement module
into its NIC Module slot until the metal clasps at the top and bottom of the GBIC module
click into place.
Install a NIC Access Module
You must install a NIC Access Module opposite each installed NIC Module. To install a NIC
Access Module, follow the same procedure described in “Install an HFC Connector Module or
SIM” on page 105.
The GBIC module can be installed only one way. If you
orient the module in its slot incorrectly, it will stop about
halfway into the slot. If this occurs, remove the GBIC
module, rotate it 180°, and reinstall it.
