The systems have two power modules, each holding three hot-swappable power supplies. One module is on
the front of the system and the other module is on the rear. Both must be replaced to accommodate the A211
power supply units. The A211 power supplies and power module are keyed to prevent intermixing with older
power supplies and power modules.
Caution –
The A211 power supplies require System Management Software (SMS) 1.6 with patches
124319-02 (or higher) and 123300-05 (or higher) or subsequent compatible versions.
For the latest patch information go to http://sunsolve.sun.com. Installation information and
README files are included in the patch download.
