I wrote a previous article about obtaining the BIOS version on a Dell Poweredge 650 server which had the end goal of updating the BIOS version on the server if a new BIOS version was available. So after obtaining the BIOS version of the Poweredge 650 server I needed the Dell Service Tag from the server so I could use Dell’s web site to see if a new BIOS version was available. Below is information on how to obtain the Dell Service Tag as well as the Dell Express Service code for the server if it is running a Linux operating system.
Obtain Dell Service Tag From A Server Running Linux:
The dmidecode command can be used to output the Dell Service Tag with ease. If no switches are used then you will be required to sift through the output of just using the dmidecode command however when using the -s switch and specifying the system-serial-number option only the Dell Service Tag will be output as shown in the below example.
- [root@cent1 ~]# dmidecode -s system-serial-number
The above Service Tag has been modified from the true Service Tag that was output but as you can see the output is a combination of letters and numbers. This can be input into the Dell support web site to provide information on the system including drivers and other downloads such as the BIOS that may be available.
Obtain Dell Express Service Code From Dell Service Tag:
Another item that you might need if you are calling Dell is the Express Service Code which is simply a base10 decimal conversion of the Dell Service Tag which is initially in base36 format. Copy the service tag to your clipboard and then input it on this site which is a Dell Service Tag converter application. In our example with a Service Tag of F3TBC11 the Dell Express Service Code is 328-823-712-37 as shown in the output of the web site used to convert the Service Tag.
You now have both the Dell Service Tag and the Dell Express Service Code without having to look for the tiny sticker on the server which may not even exist on the Dell server anymore.
