Interconnect Cables - Dell EMC ML3 User Manual

Important: Under normal circumstances, when the library is powered off by using the front Power, the
robot automatically parks and locks into the Base Module behind the Operator Panel. If you are given a
choice during the power down procedure, choose the default park position. To protect the spooling cable
or other sensitive parts, the accessor must be in the Base Module before any modules are removed from
the library. If it is not, follow the procedure for returning the accessor to the base module. See "Returning
the accessor to the Base Module" on page 127.
Verify that all host processes are idle.
Removing the Module cables
1. Remove the power cords from the module that is replaced.
2. Remove the expansion interconnect cables ( 1 ) from the module that is replaced and from the
modules that are connected to it.

Note: Completely removing the cables from both ends prevents damaging the expansion interconnect
cables during module removal and replacement.
3. Remove any SAS, FC, or Ethernet cables from the module that is replaced.
4. Remove the USB device, if present.
Removing the tape drives
Remove any tape drives from the module that is replaced. The library tracks the drive locations and
issues events if the drives aren't in the expected locations. Note the drive locations so they can be
replaced in the same order and drive bays.
1. Use your fingers to loosen the blue captive thumbscrews on the tape drive.
2. Pull straight back on the tape drive handle while the bottom of the drive is supported to remove it
from the module.
