Expansion Unit Deployment And Topology - Synology SA3600 Hardware Installation Manual

Expansion Unit Deployment and Topology

SA3600 supports RX1217sas (12-bay) and RX2417sas (24-bay) expansion units, providing seamless storage
expansion whenever needed. This section will guide you through how to connect the expansion units to your
Synology NAS.
To connect RX1217sas/RX2417sas with SA3600:
1 Connect one end of the expansion cable to the SAS OUT port of your SA3600 and the other to the SAS IN port
of RX1217sas/RX2417sas. Make sure the release band (in blue) of the cable faces rightward when plugging
into the SA3600, and that of the cable faces upward when plugging into RX1217sas/RX2417sas; otherwise,
the SA3600 and expansion unit will not be correctly connected.
2 Connect one end of the power cord(s) to the power port of RX1217sas/RX2417sas, and the other to the power
outlet(s). RX1217sas/RX2417sas will automatically power on once the power cords are correctly connected.
Note:
• Your RX1217sas/RX2417sas comes equipped with a redundant power supply system, allowing two power
cords to be connected. The system may be powered on with only one power cord, but we recommend using
two power cords to avoid unexpected power failures.
• Your Synology NAS supports up to seven expansion units.
Important: Do not remove the expansion cable while the host device is still powered on. Doing so may result in data
loss.
