Chapter4 Provisioning Using ASH and SNMP
Set Date and Time
Step 4 Log in again using Step 4 through Step 6 in “Log In via RS-232 (EIA/TIA -232) Port Using
HyperTerminal” section on page4-1.
You are now connected to the ONS152 16 EDFA2 via Telnet.
4.4 Set Date and Time
Use the snmp attribute set local cerent15216EdfaRtcDateAndTimeLocalString command to set the
date, time, and time zone. Entries must follow this format: “yyyy-m-d,h:m:s.s +h:m”. Following the
space, the time zone is set as +/– hours from Greenwich Mean Time (GMT) (also designated as universal
coordinated time (UTC)) followed by a colon and minutes ahead for daylight savings. For example,
Pacific Daylight Time would be –8:60 and Greenwich Mean Time would be +0:0. See Example 4-4.
Example4-4 Setting the Date and Time
ash:hostname:ONS15216 EDFA2> snmp attribute set local cerent15216EdfaRtcDateAndTime LocalString
"2002-6-30,14:8:30.0 -8:60"
4.5 Set Power Bus Mode (Simplex or Duplex)
The ONS 15216 EDFA2 allows users to set a simplex (one power source–Bus A) or duplex (redundant
power source–Bus A and Bus B) Power Bus mode. Use the snmp attribute set local
cerent15216EdfaPowerBusMode command to set the desired Power Bus mode. The default mode is
duplex. See Example 4-5.
Example4-5 Setting the Power Bus Mode
ash:hostname:ONS15216 EDFA2> snmp attribute set local cerent15216EdfaPowerBusMode simp lex
4.6 Verify Amplifier Operational Status
To ensure that the amplifier is working correctly on the optical level, you must verify the amplifier
operational status. Use the snmp table display local cerent1521 6EdfaOverallStatusGroup command
to verify amplifier operational status. Example4-6 displays the output of this command.
Example4-6 Verifying the Amplifier Operations Status
