MPU active/standby status LED
Management Ethernet port LEDs
The MPU has one LINK LED and one ACT LED to indicate the link status and data forwarding status of the
management Ethernet port.
Table 61 Management Ethernet port LED description
LIN
On Flashing A link is present, and the management Ethernet port is transmitting data.
On Off A link is present.
Off Off No link is present.
Power status LEDs (PWR)
• If an MPU provides only one power status LED (PWR), see Table 62 for the LED description.
• If an MPU provides multiple LEDs with numbers (for example, PWR1 and PWR2), each LED
corresponds to a hot swappable power supply with the same number (the power supply number is
marked on the chassis). See Table 63 f
or the LED description.
Table 62 Description for PWR LEDs without numbers
O
On Off All power supplies in the chassis are operating correctly.
Off On
A power supply has no power output. (The cause can be: the power
supply is faulty or not switched on; a power cord connection problem has
occurred; the external power supply is unavailable.)
Off Off
This status has occurred in the following cases:
• No power supply is installed in the chassis.
• No power supplies in the chassis output power. (The cause can be: the
power supplies are faulty or not switched on; a power cord connection
problem has occurred; the external power supply is unavailable.)
