Upgrading Hardware DPEs
Upgrading Hardware DPEs
You may remotely patch your DPE devices, or if you have local access to these devices, you can fully
reimage them. Refer to the recovery CD-ROM release notes that accompanied the DPE device for the
required reimaging procedure.
Complete these steps to upgrade the DPE component to release 2.7:
Caution If the hardware DPE is rebooted or powered off while a patch is being applied, the device is left in an
unknown state and must be completely reimaged. Refer to either the DPE-590 or DPE-2115 Recovery
CD-ROM Release Notes that accompany the DPE device, for reimaging instructions.
Step 1 Open an FTP connection to each DPE to be patched and upload the patch bundle to the DPE. See step 3
for the appropriate DPE file name.
Note When opening the FTP connection, you must enter the username admin and the login password
chosen for the selected DPE.
Step 2 After an FTP connection is established, change directory to ‘incoming’ using this command at the FTP
prompt:
cd incoming
This will locate the patch file so that the DPE can easily find it.
Step 3 Select the upgrade file corresponding to the BACC version currently running on your DPE and FTP it to
the DPE.
For example, you use this command to FTP the DPE-590 upgrade file from BACC 2.6.x to BACC 2.7:
bin
put dpe-590-26xto27-upgrade.bpr
Step 4 Log into each DPE, in the enable mode, and run the upgrade command. You are prompted to select the
2.7 upgrade file and apply it. After the upgrade is finished, the DPE will reboot.
Step 5 Log into each DPE, in the enable mode, and run the show version command. This should identify the
current version running on the DPE as BACC 2.7.
