1 Identify sets to be downloaded. If possible, organize by Set type, TN
Range, or DN Range.
a. To determine set quantity and type, use LDs 97 and 32 to print the
ranges of sets using the commands given below.
2 Establish set quantity.
3 Estimate the time required for download. Downloading sets with the
North America reduced language set file takes nine minutes per set (on
the M3905 it takes 12 minutes). Language sets other that the North
America reduced language set file take 12 minutes to download. On
small systems (Option 11C), you can download four sets in parallel. On
large systems, you can download one set per XPEC in parallel, up to a
maximum of 8 on CP4 and 31 on CPP.
The following formulas provide estimates of download times:
• Small systems—North American 6 Language file:
((Quantity of M3902, 3, 4 x 9 minutes)+(quantity of M3905 x 12
minutes))/4, where 4 details the number of sets that can be downloaded
in parallel.
• Small system—Global 10 Language file:
(Quantity of M3902, 3, 4, 5 x 12 minutes)/4, where 4 details the number
of sets that can be downloaded in parallel
• Large System—North America 6 Language file:
((Quantity of M3902,3,4 x 9 minutes)+(quantity of M3905 x 12
minutes))/ number of XPEC’s (assuming even distribution of sets)
• Large System—Global 10 Language file:
((Quantity of M3902,3,4,5 x 12 minutes))/ number of XPEC’s (assuming
even distribution of sets)
