• Storwize V5030E systems can support two chains and each chain can support up to 10 expansion
enclosures.
• If a rack is to be only partially lled, install the enclosures low enough for the rack to remain stable and
enable easy access to the enclosures for servicing.
Adding an expansion enclosure chain to an existing system
If you are adding an expansion enclosure chain to an existing Storwize V5030E system, follow these
guidelines.
• You do not need to power off the system. You can add an expansion enclosure while the system is
operational.
• Add the rst expansion enclosure directly below the control enclosure.
• Add the second expansion enclosure directly above the control enclosure.
• Add the third expansion enclosure directly below the rst.
• Add the fourth expansion directly above the second, and so on.
