	Service Action Codes		Operator Intervention Messages
	Operator Information Messages		Firmware Download Procedure

When a failure occurs, the PowerVault 136T SDLT Library firmware performs error recovery and reporting. If the failure requires a service call, two-byte Service Action Codes (SACs) are generated and posted to the Operator panel. The following list details the two-byte definition.

nn represents the Service Action Code
xx represents the modifier to the Service Action Code
- 00 represents the Main Controller
- 10 represents the Picker Controller
- 20 represents the Display Assembly
- 3x represents the Drive Sled
  - x represents the Drive ID
- 40 represents the SCSI Controller
- 50 Represents the Remote Management Unit (RMU)

When an operator intervention is required, a message is generated at the Operator Panel. See Table 2 for operator intervention messages and parameters.

Additionally, information messages that relate to the current operation are posted to the Operator panel. See Table 3.

Service Action Codes

Table 1 lists the SACs and the corresponding actions that the operator can take. If the stated remedy does not clear the SAC code, information about how to contact Dell Customer Support is located in the Getting Help section.
