DDS Tape Drive Depending on the configuration, this DDS drive may be a DDS-DC drive, or a DDS-2 drive. The DDS tape drive is a 3 1/2-inch form factor DDS tape drive with data compression and a SCSI interface. It conforms to the DDS format standard for storing computer data, and incorporates a data compression capability. It's a high-capacity, high transfer-rate device for data storage on tape. Figure 1-4 shows the operating controls and features of the DDS tape drive. Cassette LED Drive LED Eject Button Figure 1-4. DDS Tape Drive Controls and Features LEDs - DDS-DC Drive The front panel has two colored LEDs: the Cassette Light and the Drive Light. A green light indicates normal operation, and an amber light indicates a warning condition. Pulsing shows activity between the drive and the SCSI bus. If the Cassette Light (left LED) shows steady amber, it means that the cassette is write-protected. If the Drive Light (right LED) shows steady amber, this indicates a fault condition. Table 1-2 lists the LED codes and their meanings. Product Information 1-7

LEDs – DDS-DC Drive
The front panel has two colored LEDs: the Cassette Light and the Drive Light. A
green
light indicates normal operation, and an
amber
light indicates a warning
condition. Pulsing shows activity between the drive and the SCSI bus.
If the Cassette Light (left LED) shows steady amber, it means that the cassette is
write–protected. If the Drive Light (right LED) shows steady amber, this indicates a
fault condition. Table 1–2 lists the LED codes and their meanings.
