Description
A tooled latch is integrated in the side cover to secure it to the rack chassis.
A standard bezel is an optional metal bezel mounted to the chassis front and shows the Dell EMC ID. A lock
on the bezel protects unauthorized access to hard drives. NFC bezel enables the iDRAC QuickSync
management function for managing the server from the front using an NFC-capable device and the free Dell
EMC OpenManage Mobile App (currently Android only). Available only from the factory and not supported
after purchase of sale.
The Trusted Platform Module (TPM) is used to generate/store keys, protect/authenticate passwords, and
create/store digital certificates. TPM 1.2 is supported.
BIOS has the ability to disable the power button function.
