# Using UCS PowerTool To Upload UCS Firmware

It’s patch time! That means time to upload the firmware bundles to all my UCS domains. Instead of doing it manually I figured i would create a quick script to do that for me.

#### Preparing to Execute the Script

The script is pretty straight forward, just need to define a few variables seen below and then you execute the script. I will walk you through the process.

#Define Variables
$cred = Get-Credential$domains = "ucs01.lab.local","ucs02.lab.local"
$fileName = "C:\Users\david\Downloads\ucs-k9-bundle-infra.2.2.6e.A.bin" #Cycles through each UCS uploading the UCS Firmware Foreach ($ucs in $domains) { Connect-UCS$ucs -Credential $cred Send-UcsFirmware -LiteralPath$fileName | Watch-Ucs -Property TransferState -SuccessValue downloaded -PollSec 30 -TimeoutSec 600
Disconnect-UCS
}
