DDS Tape Module
Status Lights
Table 3 lists the status light indications and actions for the tape light and clean light.
Tape Light
The tape light monitors the following tape parameters:
• tape loading or unloading
• tape loaded or unloaded
• self-test in progress
• read/write activity
Clean Light
The DDS tape module monitors the number of errors occurring during read and write operations. If the
number of errors exceeds the error limit, the clean light flashes amber. This condition can be caused by a
hard read or write error, dirty tape heads, or the tape nearing the end of its useful life.
If the clean light flashes amber:
1. Clean the tape heads.
2. Repeat the last operation and see if the clean light flashes again.
3. If the clean light flashes again, copy the data from the old tape onto a new tape then discard the old
tape. The clean light is cleared after you load a cleaning cartridge, or when the DDS tape module is
power cycled.
4. If the clean light flashes after cleaning the tape heads, you should service the DDS tape module.
