Chapter 7 Troubleshooting the Installation Troubleshooting the Hardware Table 7-3 Possible Problems and Solutions for Hardware-Based Out-of-Service States on the Cisco WebEx Node SPA and SPA-DSP (continued) Possible Problem Observations and Comments Temperature or voltage sensors have values that are not in the range of safe operation for the Cisco WebEx Node SPA and SPA-DSP. • The show hw-module subslot all oir command displays an "Environmental limits exceeded" reason code. • The show hw-module subslot sensors command displays the actual values for the temperature and voltage on the Cisco WebEx Node SPA, as shown in the following example: Router# show hw-module subslot 0/0 sensors SPA-WMA-K9[0/0] temperature sensor 0, reading: 31C SPA-WMA-K9[0/0] temperature sensor 1, reading: 36C SPA-WMA-K9[0/0] temperature sensor 2, reading: 48C SPA-WMA-K9[0/0] temperature sensor 3, reading: 51C SPA-WMA-K9[0/0] temperature sensor 4, reading: 57C SPA-WMA-K9[0/0] temperature sensor 5, reading: 32C SPA-WMA-K9[0/0] nominal: 3.300V, reading: 3.257V SPA-WMA-K9[0/0] nominal: 2.500V, reading: 2.454V SPA-WMA-K9[0/0] nominal: 5.000V, reading: 5.038V SPA-WMA-K9[0/0] nominal: 1.200V, reading: 1.195V SPA-WMA-K9[0/0] nominal: 1.100V, reading: 1.097V SPA-WMA-K9[0/0] nominal: 1.000V, reading: 0.998V SPA-WMA-K9[0/0] nominal: 0.900V, reading: 0.892V SPA-WMA-K9[0/0] nominal: 1.800V, reading: 1.785V Solutions 1. Enter the show logging | include TEMP_SHUTDOWN command and look for a temperature shutdown error message. The following is an example of an error message due to excessive temperature: *Jan 27 17:46:22.285: %SPA-0-TEMP_SHUTDOWN: SIP1/1: SPA-WMA-K9[1/1] temperature too high on sensor 2. (90C) SPA has been shut down. Tip If you do not find a temperature shutdown error message, it's possible that the logging buffer has overflowed from too many warning messages. Enter the show logging | include TEMP_WARNING command to confirm. 2. If you find a temperature error message, then verify that the fan within the power supply is working correctly. Refer to the "Troubleshooting the Cooling Subsystem" section of the "Troubleshooting Initial Startup Problems" chapter in the Cisco ASR 1000 Series Aggregation Services Router Hardware Installation Guide. 3. If no temperature error message is found, enter the show logging | include VOLT_SHUTDOWN command to find a voltage shutdown error message. If an error messages indicates a voltage problem, then the SIP could be providing an unstable voltage to the SPA, or there might be a hardware problem on the Cisco WebEx Node SPA itself. Try installing the SPA into another SIP and see if the problem continues. If the problem still occurs, then there is a voltage problem on the Cisco WebEx Node SPA.

Troubleshooting the Installation

Troubleshooting the Hardware

Temperature or

voltage sensors

have values that are

not in the range of

safe operation for

the Cisco WebEx

Node SPA and

SPA-DSP.

•

The

show hw-module subslot all oir

command

displays an “Environmental limits exceeded” reason

code.

•

The

show hw-module subslot sensors

command

displays the actual values for the temperature and

voltage on the Cisco WebEx Node SPA, as shown in

the following example:

Router#

show hw-module subslot 0/0 sensors

SPA-WMA-K9[0/0] temperature sensor 0, reading: 31C

SPA-WMA-K9[0/0] temperature sensor 1, reading: 36C

SPA-WMA-K9[0/0] temperature sensor 2, reading: 48C

SPA-WMA-K9[0/0] temperature sensor 3, reading: 51C

SPA-WMA-K9[0/0] temperature sensor 4, reading: 57C

SPA-WMA-K9[0/0] temperature sensor 5, reading: 32C

SPA-WMA-K9[0/0] nominal: 3.300V, reading: 3.257V

SPA-WMA-K9[0/0] nominal: 2.500V, reading: 2.454V

SPA-WMA-K9[0/0] nominal: 5.000V, reading: 5.038V

SPA-WMA-K9[0/0] nominal: 1.200V, reading: 1.195V

SPA-WMA-K9[0/0] nominal: 1.100V, reading: 1.097V

SPA-WMA-K9[0/0] nominal: 1.000V, reading: 0.998V

SPA-WMA-K9[0/0] nominal: 0.900V, reading: 0.892V

SPA-WMA-K9[0/0] nominal: 1.800V, reading: 1.785V

Enter the

show logging | include

TEMP_SHUTDOWN

command and

look for a temperature shutdown error

message.

The following is an example of an

error message due to excessive

temperature:

*Jan 27 17:46:22.285:

%SPA-0-TEMP_SHUTDOWN: SIP1/1:

SPA-WMA-K9[1/1] temperature too

high on sensor 2. (90C) SPA has

been shut down.

Tip

If you do not find a temperature

shutdown error message, it’s

possible that the logging buffer

has overflowed from too many

warning messages. Enter the

show

logging | include

TEMP_WARNING

command to

confirm.

If you find a temperature error

message, then verify that the fan

within the power supply is working

correctly.

Refer to the “Troubleshooting the

Cooling Subsystem” section of the

“Troubleshooting Initial Startup

Problems” chapter in the

Cisco ASR

1000 Series Aggregation Services

Router Hardware Installation Guide

If no temperature error message is

found, enter the

show logging |

include VOLT_SHUTDOWN

command to find a voltage shutdown

error message.

If an error messages indicates a

voltage problem, then the SIP could

be providing an unstable voltage to

the SPA, or there might be a hardware

problem on the Cisco WebEx Node

SPA itself.

Try installing the SPA into another

SIP and see if the problem continues.

If the problem still occurs, then there

is a voltage problem on the Cisco

WebEx Node SPA.
