Locate the service tag
ME5 Series storage systems are identified by a unique Service Tag and Express Service Code.
The Service Tag and Express Service Code can be 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 PowerVault ME5 Series Storage System document provided with your ME5 Series enclosure.
● Scan the QRL to get immediate access to your system information, using your smart phone or tablet.
Enclosure configurations
The storage system supports three controller enclosure configurations.
● The 2U12 controller enclosure holds up to 12 low profile 3.5" form factor disk drives in a horizontal orientation.
● The 2U24 controller enclosure holds up to 24 low profile 2.5" form factor disk drives in a vertical orientation.
● The 5U84 controller enclosure holds up to 84 low profile 3.5" form factor disk drives in a vertical orientation within a disk
drawer. The 5U84 controller enclosure contains two drawers that each hold 42 disks. If 2.5" disks are used, a 3.5" adapter is
required.
The 2U12 and 2U24 enclosures support single or dual-controller module configurations, but the 5U84 enclosure only supports
a dual-controller module configuration. If a partner controller module fails, the storage system fails over and runs on a single
controller module until the redundancy is restored. For 2U enclosures, a controller module must be installed in slot A, and a
