8 ETH 2/1, ETH 2/2 Install supported small form factor pluggable (SFP) modules in these two SFP ports.
For more information and supported SFPs, see the “Small Form-Factor Pluggable
(SFP) Ports” section on page 3-24. These physical ports share the ETH 2/1 and
ETH 2/2 interfaces with the 100/1000 Mbps ports, as described in the “Combo Ports”
section on page 3-25.
9 – The LEDs indicate alarm port status and connection status for Ethernet, WiFi, and
GPS connections. The LED label is located in the center of the chassis (see
