Default port for SSH is 222 on SBCE server.
If you have webpage access (for example with ucsec) you could go in and install and then activate the ASG authentication with an auth file. Then you could access the CLI using init/craft, then get to root (sudo -s, for example) and then reset ipcs.
Note: sudo -s may not work on newer 7.x SBCs. May need to restore root password from console.
For 8.x root restore is in documentation
For SBCE R8.x, you can use following procedure to enable EASG. Then you can use init account for CLI login, the su - sroot to login sroot, and use passwd ipcs to reset the password.
Enabling EASG Procedure
1. Log on to the EMS web interface with administrator credentials.
2. From the Device drop-down list, select EMS.
3. Navigate to System Administration > AAA.
4. On the EASG tab, click Enable if EASG is not already enabled.
To check if account is locked:
[root@tel-prod-ems ~]# passwd -S ipcs
ipcs PS 2021-10-27 0 99999 7 -1 (Password set, SHA512 crypt.)
To renew password:
[root@tel-prod-ems ~]# passwd ipcs
