Module Status Lights
Each module within the storage system has at least one status light on its front panel (see Figure 22). The
DDS tape module has two status lights (see Figure 23). Status lights show the results of power-on self-
tests and indicate the functional status of the device within the module. Table 6 through Table 9 list the
status light indications and recommended actions for the modules.
