Upgrading software in a Pure BPS 2000 stack

To download, or upgrade, software in a Pure BPS 2000 stack:

1 Download the operational software image.

2 Download the diagnostics image.

However, if you are currently using software version 1.0, 1.0.1, or 1.1, you must

upgrade to software version 1.1.1 before upgrading to version 2.5.2.

Upgrading software in a Hybrid stack

The physical order of the units and the unit numbering in the Hybrid stack does

not affect the upgrading process at all, however you must ensure that a BPS 2000

switch is Unit 1 and is the base unit.

Note: Once you begin the upgrading process, do not interrupt the

process at all.

Note: In order to upgrade BayStack 410 and BayStack 450 software in a

hybrid stack, the stack must be fully redundant. All cables in the stack

must be installed and operating properly. If the cables are not installed

properly, the BayStack units will fail to upgrade. A message is displayed

on consoles connected to BayStack 410 and BayStack 450 switches:

Primload Error - 2009 Switch will reset in 5

seconds...
