Understanding the Base Input Output/System Controller module
The Base Input Output/System Controller (BIO/SC) provides backhaul support, system control services, and
timing distribution to internal IP-RN 8000 components. See Figure 12
and Table 13.
The primary BIO/SC installs in slot 3. The optional redundant BIO/SC installs in slot 7.
The BIO/SC is field-replaceable and hot swappable. Hot swapping a BIO/SC is service disrupting if it is the
active BIO/SC in a redundant configuration. Therefore switching service to the standby BIO/SC in
redundant systems before replacing the module is recommended.
For information about installing the BIO/SC module:
• See Understanding the installation process
on page 40.
• See Understanding the module installation process
on page 104.
