Scheduled power outages

When scheduling computer room power outages, the SANC40N cabinet can just be
powered off. The TCM boards keep all the port specific data stored in the battery-backed
non-volatile memory for up to 10 years. However, the dynamic data will be lost.

Unscheduled power outages

If an unexpected power outage is experienced, the SANC40N cabinet can be left in the
state it was when the power loss occurred. It is recommended to set the AC Power
Supply switches to the 0 (Off) position before power resumes if not an inconvenience or

If the power loss continues past 48 hours, then set the AC Power Supply switches to 0
(Off).
