Gigabit Ethernet Cluster Interconnect Ports - Hitachi NAS Platform 4000 Series Hardware Reference Manual

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:

10 Gigabit Ethernet cluster interconnect ports

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>
