Combo interface
The S6520X-16ST-SI and S6520X-24ST-SI switches each provide two combo interfaces on the front
panel. Each combo interface contains an SFP+ port and a 1/10GBASE-T autosensing Ethernet port.
Only one of these two ports is active at a time.
An LSPM4G4T6P interface module provides two combo interfaces. Each combo interface contains
an SFP port and a 10/100/1000BASE-T autosensing Ethernet port. Only one of these two ports is
active at a time.
LEDs
System status LED
The system status LED shows the operating state of the switch.
Table 35 System status LED description
LED mark Status Description
SYS
Steady green The switch is operating correctly.
Flashing green (1 Hz) The switch is performing power-on self test (POST).
Steady red The switch has failed the POST or is faulty.
Off The switch is powered off.
Power module status LED
The S6520X-SI switches (except the S6520X-10XT-SI and S6520X-16XT-SI) each provide two
power module slots on the rear panel. The power status LEDs PWR1 and PWR2 on the front panel
show the operating status of power module 1 (PWR1) and power module 2 (PWR2), respectively.
