positions.
Figure 8-39. A3183A Switch Settings
Switches 1 and 2 are used to configure the data compression operation mode. The following list shows the
available options.
Note that with switch 1 on, data written to the tape will be compressed without the knowledge of the host.
Switch 3 is used to configure the drive to respond to DDS media recognition system tapes.
Switches 4 through 8 are used to specify drive connectivity and functionality according to host or customer
requirements. The default setting is all switches on.
Default switch setting = Switch 1 Off, all others On.
Preventative Maintenance
Regular cleaning of the tape heads is essential to maintain the reliable operation and performance of the tape
drive. This procedure in NO WAY damages or shortens the life of either the drive mechanism or the tape
heads. The recommended cleaning frequency is every 25 hours of tape pulling time. You are advised not to
wait for the Cleaning Needed signal to appear on the front panel before implementing the cleaning
procedure. By the time the indicator is present, the performance of the drive may already have been
impacted.
