Understanding Augmented Reality Monitoring in OpenManage Mobile | 389
Augmented Reality Monitoring attempts to visually identify the shape and patterns of the front of the chassis
from the camera feed. In addition to the general augmented reality guidelines, there are a few additional
considerations to ensure an accurate detection:
• The chassis should not be obstructed by loose or hanging wires.
• The camera should be pointed toward the chassis with which the user intends to work.
• It is recommended that only one chassis should be in the camera view at a time.
• The chassis should not move and components should not be changed while using Augmented Reality
Monitoring.
By following these guidelines, Augmented Reality Monitoring should detect the chassis within a few seconds
and provide a realistic overlay that appears fixed to the front of the chassis.
2.2 Connecting with Quick Sync 2
Quick Sync 2 is a state-of-the-art, short-range wireless management interface that uses Bluetooth Low
Energy (BLE) and Wi-Fi to securely connect to a system and quickly fetch information. Because of its
security, speed, and appropriate range, it is the ideal interface for Augmented Reality Monitoring to connect to
a chassis and read health and fault information.
The module is activated and deactivated on the Liquid Crystal Display (LCD) of the chassis. When activated,
the Quick Sync 2 BLE component begins to broadcast a beacon advertisement which can be detected by
Augmented Reality Monitoring. The broadcast signal is attenuated to a range of about 1m for security, and is
extended when a distinct and exclusive connection is established. The BLE communication is layered
underneath additional technology to transfer larger data elements and provides a version of the Transport
Layer Security (TLS) used by web servers adopted for the block-based BLE protocol. Each chassis is
validated by a certificate with a 2048-bit or larger public key. The Diffie-Hellman key exchange protocol is
used to establish a 128-bit or larger AES-GCM session key.
Although Augmented Reality Monitoring does not typically need it, Quick Sync 2 technology also contains a
Wi-Fi component for higher-bandwidth data transfer. Quick Sync 2 Wi-Fi is based on 802.11b/g/n and uses
the 2.4 GHz spectrum. Link-layer security is provided by using WPA2-PSK, with a random key generated
each time Quick Sync 2 Wi-Fi is activated and exchanged over the BLE connection. The link layer security is
complemented by TLS or SSH transport layer security used by each feature. The compute sleds in an
MX7000 chassis system are authenticated by OAuth token, with the chassis facilitating the authentication of
the iDRACs in each sled.
Note: More details about Quick Sync 2 are available in the Related Resources section of Appendix A.
