The bottom of eachpre‐made label is clear so that it does not obscure the text.Figure 59. Wrap Cable Labeld Apply a matching label to the other end of the cable.Connect SC200/SC220 EnclosuresThis section shows common cabling between the SC8000 controller and SC200/220 SASenclosures. Locate the scenario that most closely matches the Storage Center you areconfiguring and follow the instructions, modifying them as necessary.An SC200/SC220 cabling chain can contain up to 168 SAS drives, using either type ofenclosure. The maximum number of any one type of enclosure is: SC200: 14 enclosures SC220: 7 enclosuresEach SAS IO card supports up to two chains of enclosures. All enclosures attached to thesame SAS IO card must be running at the same speed (all 6 Gb or 3 Gb).SC200/220 SAS enclosure chains are cabled as follows. Side A: Enclosures are connected from B port to A port, using the top EMMs. Side B: Enclosures are connected from A port to B port, using the bottom EMMs.
