NOTE: When a switch changes between Full Switch and Fabric modes, it reboots.
NOTE: If the compute sled and fabric IOM mismatch, the health status of the compute or IOM is displayed as "Warning"
in the chassis subsystem health. However, the health status is not displayed in the chassis graphical representation on the
Chassis page, I/O Modules, and Compute pages.

Viewing hardware details
You can view information for the following IOM hardware:
● FRU
● Device Management Info
● Installed Software
● Port Information
NOTE: If the physical port is added as part of the port channel, it is listed under the port channel group instead of the
physical port.
NOTE: The URL attribute is displayed as "N/A" on the Hardware > Device Management Info page for FC IOMs, owing to
device capability limitations.
NOTE: For Quad Port Ethernet adapters, the second uplink of the MX7116n has to be connected to the IOM. When the
second uplink is connected, the number of ports in each virtual slot is increased from 8 ports to 16 ports.
Ensure that OME-Modular is updated to 1.20.10 before populating the Quad Port.
For Port Information, when you enable autonegotiation, peer devices exchange capabilities such as speed and settle
on mutually acceptable configuration. However, when the autonegotiation is disabled, the peer devices may not exchange
capabilities. Hence, Dell Technologies recommends that the configuration on both peer devices is identical.
The guidelines for autonegotiation process are as follows:
● MX9116n, MX7116n, and MX5108n IOMs support only 25G speeds on server facing ports.
● By default, autonegotiation is enabled on server facing 25G ports, as per the IEEE 802.3 Standard.
● Enabling or disabling autonegotiation is supported. However, configuring speed on server facing ports is not supported.
● When autonegotiation is enabled, Ethernet switches display speed capability of only 25G.

Configuring IOM settings
If you have the IOM device configuration privilege, you can configure the following settings for the MX9116n FSE and MX5108n
Ethernet Switch IOMs:
● Network
● Administrator password
● SNMP
● Time
You must have the network administrator privilege to configure the public management IP for the IOMs. The public IP facilitates
use of the IOM Command Line Interface (CLI) to configure and troubleshoot the IOMs.
Configuring IOM network settings
The network settings for IOMs include configuring the public management IP for the selected management port.
