Switch Control Module Connectors and LEDs

The Switch Control Module (SCM) provides master control and packet memory storage and is responsible for the following functions:

•System powerup and boot control

•Centralized routing table management

•System-wide connection management

•Interface to external Network Management Station

•Disk management (internal disk module)

•Provides two external RS-232 interfaces

•Building Integrated Timing Service support

While only one SCM is required in a configuration, you can install and configure a passive SCM for redundancy. A maximum of two SCMs are allowed in a chassis.

Note The SCM contains a small lithium battery. Some jurisdictions restrict the ways in which items containing lithium batteries may be disposed. In particular, lithium batteries or products containing lithium batteries may never be disposed of in an unregulated fire. Other restrictions might apply. See Appendix A, Specifications for lithium battery disposal warnings.

Warning Ultimate disposal of the lithium battery should be handled according to all national laws and regulations.
