Chapter 7 Setting media bay module DIP switches 105Installation and Maintenance GuideOn these two tables, note that the modules only use the top 16 DNs for each DS30 bus occupied. Ina single-density configuration, it does not matter if the bus is FDD or PDD, only the top 16 linescan be accessed.Table 23 DSM single density settings for BCM 2.5 systems upgraded to BCM 3.0 or newer softwareSelectDS30bus #Enter these switchsettings2 To assign theseDNs to DSM16 orDSM 16+To assign these DNs toDSM 32 or DSM 32+2 Custom DNrange1 2 3 4 5 602 on on on on on on 221-236 221-252(DS30 02 and 03)03 on on on on on 237-252 237-268(DS30 03 and 04)off04 on on on on on 253-268 253-284)(DS30 04 and 05)off05 on on on on 269-284 269-300(DS30 05 and 06)off off06 on on on on on 285-300 285-316(DS30 06 and 07)off071 on on on on 301-316 N/Aoff off1 If your system is configured with a 3/5 DS30 split, you cannot use DS30 07 for the DSM 16 module. You cannotconfigure the DSM 32 module for DS30 06 because the second set of DNs cannot be accessed.2 The extensions listed are based on a three-digit DN with a Start DN of 221. If your system has longer DNs or adifferent Start DN, enter the range in the blank column.Table 24 DSM single density switch settings for new BCM 3.0 (or newer) systemsSelectDS30bus #Enter these switchsettings2 To assign theseDNs to DSM 16 orDSM 16+To assign these DNs toDSM 32 or DSM 32+Top Bottom2 Custom DNrange1 2 3 4 5 602 on on on on on on 221-236 253-268 221-23603 on on on on on 253-268 285-300 253-268off04 on on on on on 285-300 317-332 285-300off05 on on on on 317-332 349-364 317-332off off06 on on on on on 349-364 381-396 349-364off071 on on on on 381-396 N/Aoff off1 If your system is configured with a 3/5 split, you cannot use DS30 07 for the DSM 16 module.
