1.9.11 No IP Connectivity Exists Between Nodes

Reset the ONS 15310-CL or ONS 15310-MA Password

Note To complete this procedure, you must be on site and have IP connectivity to the node.

Step 1 At the ONS 15310-CL or ONS 15310-MA shelf, locate the recessed button labeled LAMP TEST on the front of the unit.

Step 2 Using a pen tip or something of similar size, press in and hold down the recessed button labelled LAMP TEST for five seconds.

Step 3 Release the LAMP TEST button for approximately two seconds.

Step 4 Again press and hold down the recessed button labeled LAMP TEST for five seconds. Step 5 Again release the LAMP TEST button.

Step 6 Start a normal CTC session. At the login screen, CTC accepts the default username and password set when the system shipped. The default username is CISCO15 and the password is otbu+1. CISCO15 has Superuser rights and privileges, which allow you to create a user name and assign a password.

Note Other existing usernames and passwords are not affected by the reset. The superuser reset applies only to the local node where the procedure is performed.

Step 7 If you need to create another user name and password, complete the following steps:

a.Click the Provisioning > Security tabs and click Create.

b.Fill in the fields with a new user name and password and assign a security level.

c.Click OK.

Note After new user names and passwords are set up, including at least one Superuser, log in as a newly created Superuser and delete the default CISCO15 username and otbu+1 password to ensure security is not compromised.
