LED Indicators

Ethernet Switch Blade

Chapter 2

3 Voltage or temperature

sensors are outside of

threshold

1. Examine the other Blades in the Shelf. If all of the

healthy LEDs are illuminated red, there may be a

power failure on one of the two redundant power

busses. Check that both power busses to the ATCA are

on (energized) and check both Power Entry Modules as

described in the PEM section.

2. If voltage and temperature sensors are within

threshold, this indicates an internal hardware fault

and inoperable IPMC. Additional troubleshooting using

the SEL is required to determine the cause of failure.

3. Follow the other troubleshooting tips in 3.5to

determine if exceeded thresholds are specific to the

switch

4. If a chassis problem is suspected, replace the chassis

5. If the switch is the only FRU experiencing the problem

reset the switch by pressing the base reset button.

6. If the reset does not correct the problem, replace the

Switch.

4 Bootloader code unable to load 1. Reset the switch by pressing the base reset button.

2. If the reset does not solve the problem, the boot loader

code was not able to load.

5 The OpenArchitect Linux

image did not load successfully

from an onboard flash.

1. The OpenArchitect Linux image did not load

successfully from the onboard flash. If a recent

firmware update was performed on the switch, this

may indicate either a flash failure, or a corrupted

image was flashed during the update.

• Using a console connection configure the switch to

boot from its alternate flash. See Troubleshooting a

failed OpenArchitect Load” in the Ethernet Switch

Blade Manual for additional information.

• If the e OpenArchitect Linux image fails to load

after being directed to boot from the alternate flash

and troubleshooting fails to correct the problem,

replace the Switch.

6 Serious Internal Hardware

error

1. Reset the switch with the base reset button.

2. If the reset does not correct the problem, replace the

switch.
