find this serial number in either of the following ways:
Use the show system command

Survivability and migration options

Several options exist to minimize network disruption in the event that connectivity between the
G250/G350 and the server or media gateway controller (MGC) is lost.
MGC list. You must register the G250/G350 with at least one, and up to four, MGCs. The
●
first MGC on the list is the primary MGC. If the G250/G350 cannot connect with, or loses
its connection with, the primary MGC, it attempts to connect with the other MGCs on the
list. See
Note:
When Standard Local Survivability (SLS) is enabled, the MGC list includes the

SLS module as a fifth entry in the MGC list. For details about SLS, see
Configuring Standard Local Survivability (SLS)
Standard Local Survivability (SLS). SLS consists of a module built into the G250/G350
●
to provide partial backup MGC functionality in the event that the connection with the
primary MGC is lost. This feature allows a local G250/G350 to provide a degree of MGC
functionality when no link is available to an external MGC. It is configured on a
system-wide basis using the Provisioning and Installation Manager (PIM) (see
PIM on page 48). Alternatively, it can be configured on an individual G250/G350 using the
CLI. For more information and instructions on configuring SLS, see
