Chassis Direct
The Chassis Direct feature in OME-Modular enables users to access management consoles such as iDRAC and management
module of devices on the chassis. The MX7000 chassis has several USB ports. The Right Control Panel (RCP) on the front of
the chassis has three USB ports. Two ports are regular sized USB-A ports, for keyboards and mouse used for the chassis level
KVM. The third port is a Micro-AB port that supports USB OTG. To use Chassis Direct, connect the USB OTG port to a laptop.
The Poleg processor on the management module emulates a USB network interface and provides a network bridge into the
management VLAN. The network is same that QuickSync 2 bridges for OpenManage Mobile WiFi access.

interface or KVM. You can get access by launching a browser on the laptop and entering the URL, https://ome-m.local. A
