I just had an issue with vCenter 5.5 and ESXi 5.5 where I was unable to power on a VM.

The error which I was faced with was a relatively generic message based on the host connection status.

 

"The operation is not allowed in the current connection state of the host"

 

 

In part 1 and 2 we covered the installation of the pre-requisite's required for SCCM and the actual install of SCCM.

 

System Center Configuration Manager SCCM 2012 R2 Installation Step by Step - Part 1

System Center Configuration Manager SCCM 2012 R2 Installation Step by Step - Part 2

 

 

In this part (part 3) we will perform the post installation tasks for SCCM.

We are going to cover checking the publishing status to Active Directory, Network access account, Software update syncing from Microsoft, Email alerts and network boundaries.

 

 

 

In this blog post I will go through the installation of System Center Configuration Manager 2012 R2 as a single Primary Site Server.

SQL Server 2012 is installed on the same server which SCCM will be installed on, which itself will be Windows Server 2012.

You can install SQL Server 2012 on the same server as SCCM or on a seperate server if you wish, If you are yet to install SQL Server 2012 you can view the step by step process for that here SQL Server 2012 Install Step by Step.

 

 

In part 1 we covered the installation of the pre-requisite's required for SCCM. If you missed that catch it below, otherwise we will get on with the install of SCCM 2012 R2.

SCCM 2012 R2 Installation

 

1. Run the SCCM 2012 R2 Setup (splash.hta) and Click "Install"

 

 

I recently had a problem in my home lab where I had forgotten the password to my 3COM 2928 SFP Plus switch. So I was unable to logon to the web administration page to configure the ports.

 

As I understand it, if you do not know any usernames/passwords for the switch your only option is to perform a factory reset, losing ALL configuration from the switch. So hopefully you have an up-to-date backup of the config to re-apply, or it was a simply setup you can remember. You need to do this out of hours if it's in production!

 

Note: The default password for a 3COM 2928 SFP (I assume its the same all the 2900 series and some other 3COM switches):

 

  • Username: admin
  • Password: <blank>
