# Description:  A script that powers on blades in a UCS system.        
#               Can be configured to boot all blades, or               
#               only those associated to service profiles in a         
#               given sub-organization.

#       AUTHENTICATION             #
####################################

#Stored method of authentication - change the two values shown below
$user = "admin"
$password = "password" | ConvertTo-SecureString -AsPlainText -Force
$cred = New-Object system.Management.Automation.PSCredential($user, $password)
Connect-Ucs 192.168.0.10 -Credential $cred

#Connect using "old school" method. This method doesn't store passwords in plain text but less automatable, since you
#have to log in every time. You will be prompted for credentials just like you were logging into UCSM.
#Connect-Ucs 123.1.2.3 -Credential (Get-Credential)

#There is a method of authentication that utilizes encrypted password XML files to allow automation in a secure
#fashion, to avoid storing passwords in plain text, but keep the nice automated aspect that comes from not having
#to enter credentials every time. That method will be included in future versions.
