Overview
5 Management Port Status
The 1/10/25-Gb fiber management port has a
bicolor LED under the SFP cage that indicates
link/activity/fault:
7 Alarm Status
9 Power Status
• Off—No SFP.
• Green—Link up.
• Green, flashing—Network activity.
• Amber—SFP present, but no link.
• Off—No alarms.
• Amber—Environmental error.
• Green—Status is ok.
• Off—System is powered off. If the AC
power cord is plugged in, and the LED on
the power supply is blinking green, standby
power is still on.
Note If the LED is off, then the
power switch is set to OFF or
there is no input power.
• Green, flashing—The system has detected
a power switch toggle event, and initiated
the shutdown sequence. If the power switch
is in the OFF position, the system powers
off after shutdown is completed. Do not
remove the AC or DC power source while
this LED is blinking so that the system has
time to perform a graceful shutdown.
• Amber—The system is powering up (before
the BIOS boots). This takes one to five
seconds at most.
• Green—The system is fully powered up.
6 Managed Status
Reserved for future use.

• Off—System has not booted up yet.
• Green, flashing quickly—System is booting
up.
• Green—Normal system function.
• Amber—System boot up has failed.
• Amber, flashing—Alarm condition, system
needs service or attention and may not boot
properly.
10 Activity Status (Role of a high-availability pair)

in a high-availability pair.
