Management Ethernet interface status LEDs
The SRPU provides two management Ethernet interface status LEDs (LINK and ACT) to indicate the link
status and data forwarding status of the management Ethernet interface.

Description
LINK ACT
On Flashing A link is present, and the management Ethernet interface is transmitting data.
On Off A link is present.
Off Off No link is present.
Power status LEDs (PWR)
• If an SRPU provides only one power status LED (PWR), see Table 55 for the LED description.
• If an SRPU provides multiple LEDs with numbers (for example, PWR1 and PWR2), each LED
corresponds to a pluggable power module with the same number (the power module number is
marked on the chassis). See Table 56 for the LED description.

Description
OK FAIL
On Off All power modules in the chassis are operating correctly.
Off On
A power module has no power output. (The cause can be: the power
module is faulty or not switched on; a power cable connection problem
occurs; the external power supply is unavailable.)
Off Off
This status occurs in the following cases:
• No power module is installed in the chassis.
• No power modules in the chassis output power. (The cause can be:
the power modules are faulty or not switched on; a power cable
connection problem occurs; the external power supply is unavailable.)
