DS3950 storage subsystem and supported storage expansion
enclosure drive cabling schemes
The DS3950 supports only EXP395 and EXP810 storage expansion enclosures. To
attach one or more EXP810 storage expansion enclosures to the DS3950 storage
subsystem, you must purchase the Attach EXP810 to DS3950 Activation feature
option. Contact your IBM marketing representative for more information about
purchasing feature options.
The cabling schemes for the EXP395 and EXP810 storage expansion enclosures are
the same. This section describes the instructions only for the EXP395; use the same
diagrams and procedures to cable the DS3950 to one or more EXP810 storage
expansion enclosures.
The following sections show cabling schemes for supported storage expansion
enclosures and the DS3950 storage subsystem:
