 HPM.1 Firmware Upgrade

ATCA-9305 User’s Manual

The ATCA-9305 supports two 10/100/1000BASE-T ports on Base Interface Channels 0 and 
1, and two 10 GbE XAUI ports to the Fabric channels. Depending on the board configura-
tion, either two or six 10 GbE XAUI ports route to the optional rear transition module (RTM). 

 shows the Point-to-point Connectivity Record Link Descriptors for the ATCA-

9305. 

Note:

Table 7-50:

 

The ATCA-9305 IPMC firmware supports a reliable field upgrade procedure compliant with 
the HPM.1 specification. The prominent features of the firmware upgrade procedure are:

• The upgrade can be performed either over the payload serial interface or IPMB-0.

• The upgrade procedure is performed while the ATCA-9305 is online and operating 

normally.

• The upgrades are reliable. A failure in the download (error or interruption) does not 

disturb the ATCA-9305’s ability to continue using the “old” firmware or its ability to 
restart the download process.

• The upgrades are reversible. The ATCA-9305 IPMC automatically reverts back to the 

previous firmware if there is a problem when first running the new code, and can be 
reverted manually using the HPM.1-defined Manual Rollback command.
