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 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 Wi-Fi access.

Remove the USB cable that is connected to the front panel and AC power cycle the chassis.

With the system that is connected to the USB OTG port on the chassis, you can access the MM user interface and iDRAC user

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

chassis phonebook page which contains a list of entries to the available devices on the chassis, is displayed. This option provides

a better experience than the front panel KVM, which provides access only the command-line prompt access for OME-Modular.

Select the check box to enable accessing the MX7000 chassis from a host such as a laptop or server, using a USB On-The-Go

(OTG) cable. Connect the USB OTG cable from the host to the micro USB port on the front panel (right control panel) of the

MX7000 chassis. On successful connection, LED under the micro-USB on the right control panel of MX7000 chassis turns green

and USB Ethernet adapter is displayed on the host. The chassis is automatically configured with an IPV4 and IPV6 address. After

ensuring that the addresses are configured, open a web browser and enter the URL, https://ome-m.local in the address

bar.

On laptops running Windows, if the IPV6 traffic is blocked, check the Remote Network Driver Interface Specification (RNDIS)

interface for IPv6 address. You may be able to access chassis phonebook page through IPv4, but iDRAC and OME-Modular web

consoles are inaccessible. In that case, enable IPv6 traffic flow on the system.

When you enable or disable the Chassis Direct feature in OME-Modular, the following error codes are displayed:

The Chassis Direct feature in OME-Modular has a mutual exclusivity with the Quick Sync feature. Before downgrading the

management module firmware from 1.10.00 version to an earlier version, remove the USB cable that is connected to the front

panel of chassis. If USB cable is not removed and 1.10.00 firmware is downgraded, the Quick Sync feature may be degraded. AC

power cycle of chassis to restore Quick Sync back to health.

● The chassis has Quick Sync, and the Chassis Direct feature is enabled. That is, the USB cable is attached to the USB

connector on the front panel.

● The management module version is downgraded from 1.10.00 to an earlier version.
