This task will track the replacement of the scs-ulsfo with the future-scs-ulsfo (updated model with dual power input and does away with the requirement of cross over cables.)
Since this does away with cross over cables, we will need to order some replacement orange patch cables to replace the ones listed below:
| port # | device | length of replacement orange patch cable (in feet) |
| 1 | cr3-ulsfo | 3 |
| 2 | asw1-ulsfo | 3 |
| 3 | mr1-ulsfo | 2 |
| 4 | cr4-ulsfo | 6 |
| 5 | asw2-ulsfo | 6 |
| 6 | ps-103.02.22 | 4 |
| 7 | ps-103.02.23 | 6 |
| 8 | atlas-ulsfo (not connected yet) | 6 |
PLANNED MAINTENANCE WINDOW IS 2019-08-14 @ ~18:00 GMT to ~20:00 GMT
Work checklist:
- - plan unavailability to serial/mgmt to all the devices listed above - email team list with details
- - save scs-ulsfo config to local laptop for migration/restoration
- - wipe config of existing scs-ulsfo and remove it from the rack (update netbox status and racking assignment)
- - install new scs-ulsfo in old rack U
- - restore old config, test that scs console is online, login works, old ports are listed
- - update to syslog.anycast.wmnet and dns to 10.3.0.1
