1.14.2 Duplex configuration
In the duplex configuration, redundancy is provided for the Control Modules. In this configuration the 9700 is
equipped with two CMs. The two CMs operate in conjunction, one operating as the Active system controller,
while the other CM operates as a hot standby mate controller. In this configuration, if a failure occurs on one
Control Module, the mate will take activity and continue operation with no service interruption. The CM can be
installed in either slot 8/9 or 12/13, however for consistency in this document, slot 8/9 will be used for installing
the first CM (the second CM is installed later in this section).
To install the CMs:
1. As indicated earlier, the chassis comes with filler plates installed. Remove the filler plates from the two slots
(8 and 9 and 12 and 13) where the CMs will be installed.
2. Take the card from its antistatic container. (Set aside the Special Instructions for Ferrite instructions and the
ferrite for the Ethernet cable. Refer to Section
1.18.3 .)
3. Follow the card installation procedure detailed in section 1.13 .
