Table D-1: Log messages available from the Cisco DVB INA2320
Code Type Message text Description

00210000

Information

INA initialized successfully

The INA has started successfully.

00210001

Error

Normal memory allocation error

The INA was not able to start because the specified configuration requires too much normal RAM. One or more of the following values must be decreased:

Basic/Max Broadcast Connections

Vc/Vc Max Connections

Modem/Md Max Count

Ip/Max Vcs

Ip/Max Cache Addresses

00210002

Error

I/O memory allocation error

The INA was not able to start because the specified configuration requires too much I/O RAM. One or more of the following values must be decreased:

Basic/No Rx Broadcast Buffers

Basic/Max Broadcast Frame Size

Ip/Max Upstream Rx Buffers

Ip/Max Downstream Rx Buffers

00270000

Error

Failed to initialize the demodulator hardware.

Error = <Error code>

The demodulator driver was not able to initialize the demodulator hardware because of a hardware problem. The following error codes can be returned:

Error codes Description
0x00270001 Error loading FPGA
0x00270002 Error initializing STEL module
0x00270003 Error using I2C bus
0x00270004 Error initializing Read-Solomon decoder
0x00270005 Error one or more adapters not found
0x00270006 Error software configuration error

00270001

Warning

No cells received in the past 60 minutes for demodulator <nn>

No ATM cells have been received on the demodulator <nn> for the last 60 minutes.

The reason can be:

There is no user on the network

The network configuration is wrong

The demodulator does not function properly

00260000

Error

Failed to initialize the modulator hardware.

Error = <Error code>

The modulator driver was not able to initialize the modulator hardware because of a hardware problem. The following error codes can be returned:

Error codes Description
0x00260001 Modulator adapter not found
0x00260002 More than one modulator adapter found
0x00260003 Base address error
0x00260004 Interrupt number error
0x00260005 Error loading FPGA
0x00260006 Error programming FIFO
0x00260007 Error programming modulation chip
0x00260008 Operation system error

00260001

Error

Transmission error. No connection to the modulator adapter.

A DMA of data to the modulator has not been possible. This is probably caused by a hardware error.

Restart the INA. If this does not help, contact your service partner.

00260002

Error

No interrupts received from the modulator adapter.

The modulator has stopped generating interrupts. The INA can not work without these interrupts.

Restart the INA. If this does not help, contact your service partner.

00260003

Error

No MAC upstream marker ready for 3 ms transmission.

Every 3 ms the MAC protocol in the INA must send a MAC upstream marker frame on the downstream. If the INA (for some reason) has not had time to generate this frame in a 3 ms period, this message is generated.

This message should normally not be generated; if this message is generated with long intervals (> 5 minutes), then there is no reason to take any action on it. If the message is generated more frequently, contact your system administrator.

00260004

Error

Wrong number of 1 ms interrupts received from modulator. 60000 interrupts in <nn> seconds.

The modulator is not generating the correct number of interrupts. This is normally only caused by a hardware error.

The cause for this error can be a change of inaDate and inaTime.

00280000

Warning

Modem power ranging error, offset: <nn> dB, Demod: <d>, Mac: <ma>

A modem was not allowed to sign on to the INA, because the modem was not able perform correct power ranging. <nn> is the power offset in dB referring to the demodulator "Signal Level", see the "INA Demodulator Setup" section.

This is the offset to what the INA accepts the modem is sending with.

The acceptable modem power transmission power level is configured by the two configuration variables:

"Min Power Level" and "Max Power Level"

in INA MAC,

<d> is the number of the demodulator module receiving data from the cable modem.

<ma> is the MAC address of the cable modem.

00280001

Warning

Modem timing ranging error, offset: <nn> us, Demod: <d>, Mac: <ma>

A modem was not allowed to sign on to the INA as the modem was not able perform correct timing ranging. <nn> is the time offset in ns (offset to what the INA accept) the modem is sending with. The acceptable range depend on the used demodulator bandwidth (Demodulator/Dm Bandwidth Type):

1 MHz: + - 972 ns

2 MHz: + - 486 ns

<d> is the number of the demodulator receiving data from the cable modem.

<ma> is the MAC address of the cable modem.

00280002

Warning

Modem shutdown after ranging, power and time ok, Demod: <d>, Mac: <ma>, S,E,R: <ss>,<ee>,
<rr>

Modem shutdown - NOT due to ranging, Demod: <d>, Mac: <ma>, S,E,R: <ss>,<ee>,
<rr>

A modem is shut down by the INA.

<d> is the number of the demodulator receiving data from the modem.

<ma> is the MAC address of the modem.

<ss>,<ee>,<rr> tells the reason for the shutdown.

<rr> can have one of the following values:

00 : Undefined reason.

01 : Shutdown requested by higher level protocol layer.

02 : Time Out: Too many retries.

03 : Calibration: Too many retries.

04 : Connect Response message received with illegal Connection ID.

05 : Release Response message received with illegal Connection ID.

06 : Reservation ID Response message received with illegal Connection ID.

In case of unexpected shutdown, please write the message down and contact the system responsible.

00280003

Error

MAC protocol memory requirements error: 0x<xx>

<xx> can have one of the following values:

00280001 Illegal Initialization Sequence. Contact your service partner.

00280003 Illegal Downstream Frequency. Less than 1 MHz. Change the value of the configuration variable.

00280004 Illegal Upstream Frequency. Less than 1 MHz. Change the values of the configuration variables.

00280005 Illegal Upstream Data Rate. Only 1.544 and 3.088 Mbps supported. Change the values of the configuration variables.

00280004

Error

MAC protocol initialize error: 0x<xx>

<xx> can have the following value:

00280001 Illegal Initialization Sequence. Please contact your service partner.

00280005

Error

MAC protocol start error: 0x<xx>

<xx> can have one of the following values:

00280001 Illegal Initialization Sequence. Please contact your service partner.

00280002 The MAC receive buffer pool cannot be allocated. Contact your service partner.

00280006

Error

MAC protocol configuration error: Message: <xx>,<xx> <xx>,<xx> <xx>,<xx>

Attempt to send a MAC message with illegal Message Configuration.

Write the message down and contact your service partner.

00280007

Warning

MAC Protocol. Lost MAC messages: <pp> periods = <p>, <tt> total, <mm> max

Attempt to send more MAC messages than possible. If the message is generated frequently (every few minutes), write some of the messages down and contact your system responsible.
