Step 3 : Test for binding in the extension of the arm by gently pulling the enclosure out of the rack,
ensuring the cables extend properly and that the system doesn't bind at all. If it does, examine
the point at which the binding occurred and adjust the seating of cables in the baskets, check
the connections to the rails, and examine the joints of the arm to ensure that they are all
functioning properly.

5.6.1 SAS Cabling
The Ultrastar Data102 can use passive cables up to 3m in length, or active cables up to 10m, for SAS
connections to the host. All approved passive and active SAS cables are listed in the following tables.
Active Cabling
Active cables can be used for both direct (host-to-enclosure) and daisy-chain (enclosure-to-enclosure)
connections. When daisy-chaining multiple Ultrastar Data102 enclosures together, active cables must be
used between enclosures for improved signal integrity.
Important: Active Optical SAS cable support is limited to Broadcom 9300-, 9302-, and 9305-
series HBAs.
Note: MegaRAID adapters do not support the use of active SAS cables. If your configuration
requires the use of MegaRAID adapters, passive cables must be used.
