10 Gigabit Ethernet cluster interconnect ports

NAS Platform and Unified Storage Series 4000 Hardware Reference

Part Number

The 10 gigabit per second Ethernet (10 GbE) cluster ports allow you to connect cluster nodes together. The cluster ports are used only in a cluster configuration. The 10 GbE ports operate at speeds of ten (10) gigabits per second. The HNAS 4060, 4080, and 4100 models use an enhanced small form factor pluggable (SFP+) optical connector.

Do not use the 10 GbE cluster interconnect ports to connect to the customer data network (also known as the public data network).

For HNAS 4060, 4080, and 4100 models, the 10 GbE SFP+ transceiver modules are removable and interchangeable.
Note: When removed, the 10 GbE and 8 GB Fibre Channel (FC) SFP+ storage modules are indistinguishable from one another except for their part numbers. The part number is located on the side of the module housing and is only visible when the module is removed. Part number prefixes are different as follows:
  • 10 GbE: FTLX<number>
  • FC: FTLF<number>

Once connected, each 10 GbE port has two indicator LEDs; one green and one amber. These LEDs provide link status and network activity status information as follows:
Status/Activity (per port) Meaning
Status Green

(on, not flashing)

10 Gbps link present
Green flashing 10 Gbps link standby in a redundant configuration
Green off No link
Activity Amber flashing Network activity
Amber off No network activity
