Managers
The VMG-14+ SCMs fit into the dedicated SCM slots located at the left-front-edge of the chassis. Two
SCMs are required for redundancy, and an SCM in either slot can serve as the primary. When the active
is removed, the remaining SCM changes state—from standby to active.
Note:
Although each Shelf Manager module contains a mini DB25 Telco Alarm interface at the RS-232
port, telco alarm LEds, and Telco alarm cutoff push button, the current release does not support
Telco alarm functionality.
The SCM faceplate provides the LEDs and components illustrated in
