Verifying the DPE status

are lit.
2. If a disk, power, or SP assembly part displays a fault LED, try re-seating the
part.
Transferring the product serial number tag
The product serial number tag (PSNT) is a serialized label allowing EMC service to
track nested hardware material in the field. When replacing a DPE, transfer the PSNT
of the faulted DPE to the replacement DPE.
The PSNT for the DPE is a pull-out tag that is located on the front of the enclosure.
Note
Two rear tabs on the tag secure it in the enclosure and allow in to slide. If you find it
difficult to remove or insert the tag, pinch the rear of the tag together as you attempt
to remove or insert it.
Procedure
1. Remove and retain the PSNT (product serial number tag) from the faulted DPE.
Retain this tag, you will insert this into the replacement DPE.
