HP 7500/E7900 Switches and Fabric Modules - 7500-CMW520-R6708 Release Notes

NOTE:

 HP recommends you to upgrade software from the CLI when your switch operates normally.

 To ensure that the active and standby MPUs use the same software version, upgrade them by using the

same method.

 Make sure the system software and Boot ROM are compatible. For the compatibility between the system

software and Boot ROM, see the hardware and software compatibility matrix in the Release Notes.

 You can upgrade the Boot ROM for the LPUs from the CLI only.

 The command outputs in this document are for reference only.

 Generally, use incompatible ISSU to upgrade software to this version. Compatible ISSU is applicable

only to specific restricted versions. If compatible ISSU is needed, contact the technical support engineer.

Upgrade from the CLI

The upgrade procedure on a standalone switch is different from that on an Intelligent Resilient Framework

(IRF) fabric. This section describes the following topics:

 Upgrading a standalone switch

 Upgrading an IRF fabric

NOTE:

Up to two 7500 series switches can form a distributed IRF fabric. One switch is the master, and the other

is the slave.

Upgrading a standalone switch

The output shows that the switch has two MPUs, an active MPU in slot 0 and a standby MPU in slot 1. You

must upgrade software for the two MPUs.

NOTE:

You only need to upgrade the active MPU if the device has no standby MPU.

# Check the free storage space on the active and standby MPUs.
