Locating a DDM Bay or SSA DASD Model 020 or 040 Drawer in a 2105
Rack
Use the following procedure to locate a DDM bay or SSA DASD Model 020 or 040 drawer in a 2105
Model Exx/Fxx, 2105 Expansion Enclosure, or 2105 Model 100 rack.
Note: If you already know where the rack is located, its model number, and the configuration of its DDM
bays and SSA DASD Model 020 or 040 drawers, skip this procedure and go to Table 1 on page 8.
1. Record the location code of the DDM bay or SSA DASD Model 020 or 040 drawer you are
locating. The first two characters of the DDM bay or SSA DASD Model 020 or 040 drawer
location code (R#-) indicate what rack they are mounted in. Reference Figure 1 on page 7 and
Figure 2 on page 7 the two possible subsystem configurations.
2. Locate the rack number (R#-) in the following list and go to the page or step indicated:
v
R1- (2105 Model Exx or Fxx), go to “Rack Location Codes for DDM Bays in a 2105 Model
Exx/Fxx” on page 8
v
R2- (2105 Expansion Enclosure), go to “Rack Location Codes for DDM Bays in a 2105
Expansion Enclosure” on page 9
v
R2- (2105 Model 100), go to “Rack Location Codes for SSA DASD Model 020 or 040
Drawers in a 2105 Model 100” on page 11
