Configuration UCS 210 for initial setup

I am writing this blog to share my experience of implementing UCS  210 M2 blade with esxi for one of the customer.
You can look for good document in cisco.com and those are enough but i looked to capture some important point and capture these in form of screenshots so that it will be easy for one to understand the process and go with the initial configuration .

Here are the basic information about the server hardware :


1)     Rack Size required for UCS- 2U
2)     Attach a power cord to each power supply in your server, and then attach the power cord to a grounded AC power outlet.(Max Input Current-115 to 230 VAC nominal
Power Supply Specifications
Description
Specification
AC-input voltage
115 to 230 VAC nominal
(Range: 90 to 264 VAC)
AC-input frequency
50 to 60 Hz nominal
(Range: 47 to 63 Hz)
Maximum AC-input current
10 Amps
Maximum output power for each power supply
650 W (up to two power supplies can be installed)
Power supply output voltage
Main power: 12 VDC
Standby power: 5 VDC
3)     Use the supplied KVM cable to connect a keyboard and VGA monitor to the console connector on the front panel
4)     Set NIC mode, NIC redundancy, and choose whether to enable DHCP or set static network settings:
       a)     Press the Power button to boot the server. Watch for the prompt to press F8. 

       b)    During bootup, press F8 when prompted to open the BIOS CIMC Configuration Utility. 

       c)     Set the NIC mode to your choice for which ports you want to use to access the CIMC for server management 
  
 Dedicated—The two 10/100 management ports are used to access the CIMC. You have to select a NIC redundancy and IP setting.
 
Shared LOM (default)—The two 1Gb Ethernet ports are used to access the CIMC. This is the factory default setting, along with Active-active NIC redundancy and DHCP enabled.

d)  Cisco Card—The ports on an installed Cisco network adapter card are used to access the CIMC. You have to select a NIC redundancy and IP setting.

  Use this utility to change the NIC redundancy to your preference. This server has three possible NIC redundancy settings:
  None—The Ethernet ports operate independently and do not fail over if there is a problem.
> Active-standby—If an active Ethernet port fails, traffic fails over to a standby port.
> Active-active—All Ethernet ports are utilized simultaneously.

e)     Choose whether to enable DHCP for dynamic network settings, or enter static network settings  
  
f)     Press F10 to save your settings and reboot the server

5)     Connect to the CIMC for server management. Connect Ethernet cables from your LAN to the server by using the ports that you selected by your NIC Mode setting in Step 3. The Active-active and Active-passive NIC redundancy settings require you to connect to two ports.


6)     Use a browser and the IP address of the CIMC to connect to the CIMC Setup Utility. The IP address is based upon the settings that you made in Step 3 (either a static address or the address assigned by your DHCP server).
The default user name for the server is admin. The default password is password.

7)     After giving IP to CIMC in UCS reboot the server and set the Raid setting depends upon the requirement

8)     Procedure – Mapping of EXSI on UCS C- Series
a)     Step 1  Use a browser to connect to CIMC Manager using the CIMC IP address.
b)    Step 2  Log in to CIMC Manager using your administrator user ID and password.
The default user ID is admin; the default password is password.


 
c)     Step 3  Enable the Virtual Media feature, which enables the server to mount virtual drives:
>  On the CIMC Manager Server tab, click Remote Presence.
>  On the Remote Presence pane, click the Virtual Media tab and check the check box to enable Virtual Media.
>  Click Save Changes






>  Step 4 On the Remote Presence panes, click the Virtual KVM tab and then click Launch KVM Console.

Referral Spam in Blogger

By vitrue of  techedIN

Unknown or strange URLs in Blogger Stats

You are a blogger of sorts and your favourite pastime is to endlessly stare at your Blogger Stats hoping that hits will keep on coming if you just sit there and look at it, like me! And as you are looking at your "countless" number of less than 100 clicks and hits and unique views on your blog, you come across strange URLs that claim to refer your blog to people. Not bad, you think and click on the referrer link to see which is this benevolent site that sends you a lot of traffic! Ya, referrer spammers win!

Referrer Spam, which is also known as Log Spam or Referrer Bombing, is the act of "using a fake referrer url that points to the site the spammer wishes to advertise." This practice started as Blogging became popular. Bloggers, in their endless quest for 'link love', started publishing the sites that send them referrals. Some of them automated the process and linked the referrer list to the Analytics they used. Now, that encouraged spammers to send referrer spam so that the link of the site they wanted to advertise gets listed in a Blogger's Referrer List.

Bloggers with a lot of visits to their Blogs may not see these Referrer Spam often, as Referrer Spammers or Log Spammers send less than 20 to 25 automated hits to a Blog so that they will not get caught by Spam Fighting Teams of different Tech Companies. But those of us who drive less than hundred people a day to our Blogs will notice them immediately and click  on whatever godforsaken links they are referring us to.

How can we prevent unknown or strange URLs or referrer spammers from attacking our Blogger Stats or Analytics Logs? Here are a few things you can do to keep referrer spammers at bay:

    Hide your statistics  and list of top referrers so that referrer spammers look elsewhere for their link baits. This way you can save people who visit your blog from clicking on links they are not supposed to.
    Use Web Analytics Sites you trust. Some of these Analytic Sites keep their stats open and help spammers analyze your web traffic to target you. They target you if you are a blogger who gets less than 100 visits a day
    If you are using Wordpress as your Blog Platform, you can use a plug-in called Referrer Bouncer. You can go to the Referrer Bouncer from here.
    Those of you are using Blogger as you Blog Platform need to patiently wait and hope that Google will trace the Spammer one day and block him/her because he/she is sending too many automated requests to its servers. Until then, make sure that you do not publish your Blogger Stat and you do not click on any of those unfamiliar or suspicious URLs that claim to send you a lot of traffic.

MOH for Cisco Call Manager User vs Network MOH

If you ever done MOH config ( and i think that every voice engineer has done this )You might have came across these two config options:

1. Network hold moh audio source
2. User hold moh audio source


Network MOH is used when the  network put the user on hold ,Now the question arises when Network put the caller on hold
so when a user try to take someone in conference or transfer a call at that time what the other party listen is the network on hold

And when the User press the Hold button at that time what the other party listen is the User initiated music on hold.


Below is the sequence how the system prioritize the file to play for the MOH

  • Directory or line setting (Devices with no line definition,     such as gateways, do not have this level.)
  •  Device setting
  • Common Device Configuration setting
  • Cluster-wide default setting

Cisco IP Phone -Firmware upgrade procesure

Many times we require to upgrade the firmware of cisco IP Phone and we  look for the procedure to do it in internet .I did the same and decided to write this blog to summarize by search with the practical experience i have.
There are two procedure to upgrade the firmware of the phone one from CUCM and other by creaing a separte tftp server and pointing the Phone to take firmware from a stanalone tftp server which will host all the required  tftp files.

I will discuss the second approach from CUCM here...

First download the firmware from www.cisco.com  then follow the below procedure to upload the image in CUCM

  • Using your web browser, login to the Cisco IPT Platform Administration web page
  • Under the Software Upgrades menu, select Install/Upgrade.
  • Fill in the appropriate values in the Software Location section for the file you downloaded above, and click Next.
  • In the Available Software drop-down box, select the file you downloaded above, and click Next.
  • Enusre that the downloaded file has the same MD5 hash value as listed in Table 2.
  • Click Next.
  • In the Warning box, verify you have selected the correct firmware, then click Install.
  • Ensure that you received a Success message   
Now go to the CUCM admin page and change thedefault load by navigation to Device setting > Default Device Load

Remember in the OS adminpage you can find one more field called TFTP file management ,this ooption is used to upload ring file and other device pack so don't get confused with this option and "install and upgrade" option which is used to upload cop file for patch upgrade
