Support for Firmware Upgrade

 Cisco IOS XE Cupertino 17.9.1

This release introduces the firmware upgrade support for ASR 920-10SZ-PD and Cisco ASR-920-24SZ-IM, Cisco ASR-920-24SZ-M, and Cisco ASR-920-24TZ-M routers.

Starting with Cisco IOS XE Cupertino Release 17.9.1, firmware upgrade is supported on the following routers:

  • ASR 920-10SZ-PD

  • ASR-920-24SZ-IM

  • ASR-920-24SZ-M

  • ASR-920-24TZ-M

The firmware upgrade reduces unplanned hardware-related downtime caused by input voltage transients during a power outage.

  • ASR-920-12CZ-D

  • ASR-920-4SZ-D

  • ASR-920-12SZ-IM and ASR-920-12SZ-IM-CC using ASR-920-PWR-D power supply

Restrictions for Upgrading the Firmware

  • Automatic firmware upgrade is not supported, you must upgrade it manually.

  • For the upgrade to take effect, the router reboots automatically, which results in a service interruption for a few minutes.


Caution

Ensure that there’s a stable power supply during the firmware upgrade. This mitigates any unplanned hardware-related downtime in a router.

Upgrading the Firmware Manually

To upgrade the firmware, you should perform the following steps:

Procedure

Step 1

Execute the show upgrade hw-programmable command to display the current firmware version.

Example:

Router#show upgrade hw-programmable adm 0 firmware-version  
Hw-programmable ADM Firmware Versions

version[0]                version[1]                version[2]                
----------------------------------------------------------------------------
0                         1                         0

Step 2

Execute the upgrade hw-programmable command to upgrade the firmware.

Example:

Router#upgrade hw-programmable adm 0
*Jan 27 06:47:45.760: %IOSXE-3-PLATFORM: F0: cmand: ADM1066 f/w upgrade,
*Jan 27 06:47:45.764: %IOSXE-3-PLATFORM: F0: cmand: ADM1066 CONF EEPROM erase,
