For details, see Querying Product Specifications.

maintain_begin

String

No

Indicates the time at which a maintenance time window starts.

Format: HH:mm.

  • The start time and end time of the maintenance time window must indicate the time segment of a supported maintenance time window. For details about how to query the time segments of supported maintenance time windows, see Querying Maintenance Time Windows.
  • The start time must be set to 22:00, 02:00, 06:00, 10:00, 14:00, or 18:00.
  • Parameters maintain_begin and maintain_end must be set in pairs. If parameter maintain_begin is left blank, parameter maintain_end is also left blank. In this case, the system automatically set the start time to 02:00.

maintain_end

String

No

Indicates the time at which a maintenance time window ends.

Format: HH:mm.

  • The start time and end time of the maintenance time window must indicate the time segment of a supported maintenance time window. For details about how to query the time segments of supported maintenance time windows, see Querying Maintenance Time Windows.
  • The end time is four hours later than the start time. For example, if the start time is 22:00, the end time is 02:00.
  • Parameters maintain_begin and maintain_end must be set in pairs. If parameter maintain_end is left blank, parameter maintain_start is also left blank. In this case, the system automatically set the end time to 06:00.
