Release Notes for Cisco 7600 Series Router Route Switch Processor 720 ROMMON
Current Release: 12.2(33r)SRE2 Past Releases: 12.2(33r)SRD6, 12.2(33r)SRB3, 12.2(33r)SRB4, 12.2(33r)SRC3
This document describes how to determine if you need to upgrade the ROM monitor (ROMMON) on your Cisco 7600 series router Route Switch Processor 720 (RSP720). It covers the following RSP720 models: RSP720-3C-GE, RSP720-3CXL-GE, RSP720-3C-10GE, and RSP720-3CXL-10GE. This document also provides the procedure to download the new ROMMON image from Cisco.com and then upgrade the ROMMON on your RSP720.
With this procedure, you can upgrade the ROMMON image similar to the way that you upgrade the operating system software (route switching processor software or MSFC Cisco IOS software). Without this procedure, you have to order the upgrade kit and physically replace the ROMMON (boot ROM).
Note The ROMMON software upgrade procedure in this publication applies only to RSP720-3C-GE and RSP720-3CXL-GE with ROMMON Software Release 12.2(33r)SRB3 and later releases, or the RSP720-3C-10GE and RSP720-3CXL-10GE with ROMMON Software Release 12.2(33r)SRC3 and later releases.
ROMMON Software Release 12.2(33r)SRE2 and later releases are supported in Cisco 7600 series systems that are running the following:
The additional support is introduced in the ROMMON Software Release 12.2(33r) SRE2. Refer the table Upgradable Modules.
CSCug96645 RSP720 Rommon changes to support MPC8548 3.1.2 version-DDR20 Errata.
Resolved caveats in 12.2(33r)SRE
The support for NabooCR boards was not included. The support is introduced in the ROMMON Software Release 12.2(33r) SRE (CSCtl20213).
Resolved caveats in 12.2(33r)SRD6
The latency values in memory controller are not proper and Processor errata DDR20 was not implemented. These problems are resolved in ROMMON Software Release 12.2(33r)SRD6 (CSCta53511 and CSCta77537).
Resolved caveats in 12.2(33r)SRD5
The latency values in memory controller are not proper and Processor errata DDR20 was not implemented. These problems are resolved in ROMMON Software Release 12.2(33r)SRD5 (CSCta53511 and CSCta77537).
Resolved Caveats in 12.2(33r)SRD2
Original on-die termination (ODT) configuration value is not correct. This could cause dual inline memory module (DIMM) module failure upon bootup. This problem is resolved in ROMMON Software Release 12.2(33r)SRD2 (CSCsq27958).
Resolved Caveats in 12.2(33r)SRC3
After the non-volatile RAM (NVRAM) battery is switched, the route processor (RP) rommon cannot boot with an image download. This problem is resolved in ROMMON Software Release 12.2(33r)SRC3 (CSCsm03389).
Resolved Caveats in 12.2(33r)SRB4
The RSP720 and RSP720-10GE default RP ROMMON configuration register is set to 0x8000 instead of to 0x8002 to autoboot. This problem is resolved in ROMMON Software Release 12.2(33r)SRB4 (CSCsi92364).
Upgrading the RSP720 ROMMON Using Cisco IOS Commands
Before performing this procedure you need to download the new ROMMON image from Cisco.com. The download procedure is the same procedure that you use for downloading the route switching processor software images.
To download RSP720 ROMMON image from Cisco.com:
Step 1 To download Cisco 7600 Series Route Switch Processor 720 with 1 Gigabit Ethernet Uplinks, click:
Be sure to complete Step 5 before performing either or the following actions:
—An online insertion and removal (OIR) of the RSP720.
—A power cycling of the RSP720. The ROMMON upgrade might fail if you perform either of these actions before verifying that the runtime image successfully booted.
Step 5 After the system comes up, check the ROMMON information again:
Router# show rom-monitor slot 5 sp
Region F2:APPROVED, preferred
Currently running ROMMON from F2 region
The Region2 field should show “APPROVED, preferred.” The ROMMON stored in the Region2 is now the active ROMMON.
Storing More Than One ROMMON Image
The procedures in this section are optional and should be used only if you have multiple versions of the upgraded ROMMON image stored on the RSP720.
There are three regions (including the Gold region) where versions of the ROMMON image can be stored. You can use the upgrade rom-monitor slot preference and upgrade rom-monitor slot preference commands to switch between regions.
The ROMMON software upgrade feature allows you to have two upgraded ROMMON images (one in region F1, the second in region F2) in addition to the Gold ROMMON stored on the one-time programmable (OTP) EPROM section of the ROMMON. Use the upgrade rom-monitor slot preference command to select which ROMMON will be the preferred ROMMON the next time that the system is booted. You can change the preference as often as you like. The changes do not take effect until you reset the system.
To select a particular ROMMON image stored on the RSP720, perform this task:
You are about to mark F1 region of SP ROMMON in slot 5 as the boot preference region,
Step 2 Reload the route switching processor for the change to take effect:
Proceed with reload? [confirm]
Step 3 Verify the change:
Router# show rom-monitor slot 5 sp
Region F1:APPROVED, preferred
Currently running ROMMON from F1 region
You can also disqualify a specific region of ROMMON and use the other region or go back to using the Gold ROMMON stored in the OTP EPROM section by using the upgrade rom-monitor slot invalidate command.
To disqualify a specific ROMMON region, perform these steps:
