information.

To load the cleaning cartridge:

1. Make sure that the 7208 Tape Drive power is on and the Power-On Self Test has completed.

2. Grasp the cleaning cartridge by the outer edges, with the window side up and the write-protect switch facing you (refer to Figure 11 in
topic 3.4.1).

3. Slide the cartridge into the opening on the front of the 7208 Tape Drive until the loading mechanism pulls the cartridge into the drive and
the drive door closes.

After the cleaning cartridge has been fully inserted into the 7208 Tape Drive, the remainder of the cleaning process is automatic. The
7208 Tape Drive:

1. Loads the cleaning tape into the tape drive

2. Turns on the Fault status light (if the light is off)

3. Cleans the drive by moving the cleaning tape forward for approximately two minutes (the Fault status light comes on and the message
CLEANING displays)

4. Unloads and ejects the cleaning tape when the cleaning operation is complete

5. Indicates a successful cleaning operation by turning off the Fault status light

The cleaning cartridge can be used for a minimum of 18 cleaning operations. If you attempt to use the depleted cartridge, the 7208 Tape
Drive automatically detects the error, ejects the cartridge, and displays the message DEPLETED. The Fault status light remains on to
indicate that cleaning is still required. Replace the depleted cartridge with a new cleaning cartridge.

5.3 Operating in Harsh Environments

The 7208 Tape Drive is ideally suited to streaming operations, as opposed to multiple stop-and-start, random-search tape operations.
When the tape is used for frequent stop-and-start operations, it is beneficial to still have as much streaming movement as possible. This
can be accomplished by assuring that any save or restore operation is the only active operation being performed by a device connected to
the SCSI I/O controller.

Do not use as an archival tape any tape that has been used outside of the ranges specified in Figure 13 in topic 5.2 for an extended
period of time. The magnetic and physical strength of the tape will have deteriorated as a result of its exposure to the environment. Do not
store important data on such a tape; transfer the data to a newer tape for reliable archiving.

5.4 Setting the Write-Protect Switch

The position of the write-protect switch on the 8mm tape cartridge determines when you can write to the tape.

 When the switch is set to SAVE 1 , data cannot be written to the tape.
 When the switch is set to REC (Record) 2 , data can be written to and read from the tape.

Figure 14 shows the write-protect switch in the REC and SAVE positions.

An attempt to write to a data cartridge with the switch in the SAVE position will cause an error.

B.0 Appendix B. Fault Symptom Codes and Error Recovery Procedure Numbers

Use Figure 18 to resolve error messages that appear on the LCD of the 7208 Tape Drive Model 341:

1. Determine the fault symptom code (FSC) in the error message (the first two digits in the message). For example, in error message
ERR 1: AD 58 C0, the FSC is AD.

2. Locate the FSC in Figure 18 and identify the error recovery procedure (ERP) number for that FSC.

3. Locate the ERP number in Figure 19 in topic C.0, and identify the recommended error recovery procedure.

Use Figure 19 to resolve the error messages that appear on the LCD of the 7208 Tape Drive Model 341:

1. Determine the fault symptom code (FSC) in the error message. For example, in error message ERR 1: AD 58 C0, the FSC is AD.

2. Locate the FSC in Figure 18 in topic B.0 and identify the error recovery procedure (ERP) number for that FSC.

3. Locate the ERP number in Figure 19, and identify the recommended error recovery procedure. If two or more ERP codes are listed
for the fault symptom code in Figure 18 in topic B.0, perform the action for the first code, then perform the action for the second code,
and so on.
