Locate the service tag
Your ME4 Series storage system is identied by a unique Service Tag and Express Service Code.
The Service Tag and Express Service Code are found on the front of the system by pulling out the information tag. Alternatively, the
information might be on a sticker on the back of the storage system chassis. This information is used to route support calls to appropriate
personnel.
NOTE
: Quick Resource Locator (QRL):
• The QRL code contains information unique to your system. It can be found on the information tag and the Setting Up Your Dell
EMC ME4 Series Storage System hard copy document provided with your ME4 Series enclosure.
• Scan the QRL to get immediate access to your system information, using your smart phone or tablet.
