To set the SNTP server address:
At the Switched CDU: prompt, type set sntp, followed by primary or secondary, and the SNTP server
IP address or hostname. Press Enter.
NOTES:
The primary/secondary IP addresses contact the SNTP server; these addresses are populated with the external NTP pool
time zones “2.pool.ntp.org” and “1.pool.ntp.org” as default for new PT22s that have not yet been time set.
Both IPv4 and IPv6 formats are accepted for primary/secondary IP address or hostname.
