To configure the NTP select option 6 from the configuration main menu. Enter the IP
addresses as described in the IP address section of this manual. There are two time
server addresses. The RBMS Plus will use the primary server unless it fails to respond
and then it will switch to the secondary. It will not switch back unless the secondary
server fails to respond or the RBMS Plus is reset. To change a default time server IP
address to undefined, enter zeros for the IP address.
The RBMS Plus will reset itself if there is no communication with either time server
for approximately two hours. To disable the reset function, enter zero for all four
octets of the primary time server IP address. The RBMS Plus will use the secondary
time server to set the time if the second IP address is valid.
The time read from the time server is GMT. There is an option in the NTP setup to
enter a time offset to correct the time to read local time. If the time offset is
positive, east of the UK, simply enter the offset in minutes. If the time offset is
negative, west of the UK, the offset must be entered in 2’s compliment form. To
compute the value, subtract the time offset in minutes from 65536 and enter the
result. For example the offset to Eastern Daylight Time is 4 hours. 65536 - 240 =
65296. Enter 65296 as the time offset for Eastern Daylight Time. The table to the left
contains the offset value for each major time zone.
To save your changes, type “9” from the menu and hit “Enter”. The changes will be
saved in nonvolatile memory, the Telnet session will be terminated and the RBMS
Plus will reset.
4.8.7.
Restore Factory Defaults and Reset (7)
To restore the factory default settings type a 7. All SNMP, e-mail, NTP and HMS values will be set to the factory
defaults. The IP address will not be changed, however the gateway and netmask settings will be set to the factory
default values.
