Expansion Enclosure On-line Expanding
This chapter details the steps of adding expansion enclosures to an already present storage system setup.

1. Setting the expansion enclosure ID
The expansion enclosure ID is located at the front panel of the expansion enclosure. When setting expansion IDs, always set
them in order: Set the first expansion to 1, the second expansion ID in 2, and so on. The newly-added expansion enclosures
must be connected after the current setup's last expansion enclosure. Do take note that the enclosure IDs must be different
from each other.

2. Installing the newly-added expansion enclosure
Due to the expansion enclosure's heavy weight, we recommend you to install the hard drives to the expansion enclosure
after the enclosure is already installed to the rack. After the ID assignment and installation of the expansion enclosures to the
rack, you can now connect the added expansion enclosures to the current system assembly via SAS cables.
In connecting the newly-added enclosures, ensure that the SAS cables are long enough to reach between SAS ports. The
longest cable is used to connect the storage system and the last expansion enclosure. In some cases, the expansion
enclosures are not directly installed on top or bottom of the storage system, so the cabling routes may vary. In most cases, at
least one long SAS cable is required.
