5 Cabling
The guide included with an iXsystems Expansion Shelf has instructions for SAS connections. This example shows a
typical M60 connection to a pair of iXsystems ES60 expansion shelves. Detailed connection diagrams are also avail
-
. Note: The M30 does not support expansion shelves.
5.1 Expansion Shelves
With the system racked and drives installed, start connecting cables to the back of the system.
Do not plug the
power cords into a power outlet yet.
If any TrueNAS expansion shelves are connected to the M-Series, power on the expansion shelves and wait at least
two minutes before connecting power cables to the M-Series.
To set up SAS between your TrueNAS system and Expansion Shelves, cable the first port on the first TrueNAS
Controller to the first port on the first Expansion Shelf Controller. High Availability systems require another cable
from the first port on the second TrueNAS Controller to the first port on the second Expansion Shelf Controller.
We
DO NOT
recommend other cabling configurations. Contact iX Support if you need other cabling methods.
Warning: When setting up your SAS connections, please adhere to the wiring examples in this guide.
Connecting expansion shelves incorrectly will cause errors. Never cable a single controller to different
expanders on the same expansion shelf.
