10.2.8 Lost Password
If the root password for CISCO15 is lost, there is a procedure to reset it to regain full administrative
control of the ONS 15216 EDFA2. The user must be connected to the ONS 15216 EDFA2 by serial
communication, reset the power to the unit, and perform a series of commands within 60 seconds of
rebooting, according to the following procedure. This procedure resets the default user password only;
no other settings are affected.
Warning
The ONS 15216 EDFA2 ceases its optical amplification function when power is off during this process.
Traffic should be rerouted before this procedure begins.
Note If the ONS 15216 EDFA2 firmware is not version 2.3.14 or greater and the software has not been
upgraded to 2.1.0 or greater, the CISCO15 user resets to read_write access level, not read_write_admin,
which has full administrative control. Contact the Cisco TAC for assistance.
Step 1 Connect to the RS-232 (EIA/TIA-232) port.
Step 2 Open HyperTerminal. (HyperTerminal can be found in the Microsoft Windows Accessories menu.)
Step 3 Perform hard power reset of the ONS 15216 EDFA2 (disconnect and reconnect power).
Step 4 While the dots are present in the HyperTerminal window during the reboot process, enter Ctrl C on the
keyboard.
The ONS 15216 EDFA2 should boot from the firmware image. The prompt is %.
Step 5 At the hostname prompt, enter the following command within 60 seconds of rebooting:
hostname:edfaboot% user passwd set CISCO15 default
Step 6 At the hostname prompt, enter the following command:
hostname:edfaboot% login CISCO15
Password =
<enter>
Step 7 At the hostname prompt, enter the following command:
hostname:edfaboot% processor reset
After the processor reset, the default CISCO15 login password will be the default (the Enter key).
