Appliance v2.6.1(.1) documentation missing steps to add expansion shelf to operational appliance.

Firstly, a link, to all appliance documentaton:

http://www.symantec.com/docs/DOC2792

.

My question...

Appendix C, on page 112, of the Appliance v2.6.0.4 HIIC guide, details how to add an expansion shelf to an operational 52xx appliance:

http://www.symantec.com/docs/DOC7642

.

...and the 5330 v2.6.1 HIC guide details how to add an expansion shelf to a v2.6.1 5330:

http://www.symantec.com/docs/DOC7584

...as does the 5330 v2.6.1.1 HIC guide:

http://www.symantec.com/docs/DOC7593

.

...but the 5230 v2.6.1 and 5230 v2.6.1.1 HIC guides do not detail how to add an expansion shelf to an already operational v2.6.1(1) 5230 appliance.

. 

So, my question, where can I find the procedure to add an expansion shelf to an already operational v2.6.1(.1) 5230 appliance?
