Setting the real-time clock
The clock supplies accurate date and time information to the CMU. It can be set to run
with or without a connection to a network time server (SNTP):
• In the absence of an SNTP server connection, set the clock to run manually. The clock
is battery backed and will continue to operate for several days after the CMU is
switched off.
• If an SNTP server connection is available, set the clock to synchronize with the server
time at regular intervals.
Setting the real-time clock manually
To set the CMU clock to keep time without connecting to a networked time server, select
menu option Management, Time. The Time Configuration page is displayed. Set the
SNTP State attribute to ‘Disabled’: the manual clock attributes are displayed (Figure 175).
Review and update the manual clock attributes (Table 248), then select Submit Updated
Configuration.
