Powering On The Library; Half-Height Sas Dual Port - Dell EMC ML3 User Manual

v If you are using a cable with a single connector on each end, attach the other end into the
connector on the tape drive.
v If you are using a SAS fanout/Interposer cable, attach one mini-SAS connector into the connector
on each tape drive. The unused ends of the SAS fanout/Interposer cable are single channel and not
suitable for use with disk arrays. Use the other ends to connect tape drives, or coil and secure them
to the rack to minimize stress on the connectors.

Note: SAS signal rates require clean connections between the HBA and tape drive. Do not use adapters
or converters between the HBA and the tape drive. For reliable operation, use a maximum SAS cable
length of 6 meters.
Connecting USB cables
Two USB ports are on the library, one in the front and one in the rear. USB connections are used by
service personnel for diagnostic and service procedures. Attach one end of the USB cable to your
notebook or other device and the other end to the front or rear USB port of the library.
Important: USB cable lengths of more than 3 meters are NOT supported for the front or rear USB ports.
Connecting Ethernet cables
To use the Management GUI, connect an Ethernet cable from the bottom Ethernet port on the Base
Module controller to your network. See "Rear panel" on page 8 for the location of the Ethernet ports.
Note: Ethernet port A (bottom Ethernet port) is the primary port. The second Ethernet port, Port B, is for
redundancy.

Powering on the library

1. Plug the power cables into the power connectors on each module and into power outlets.
