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.
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 EMC 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 mandate.
● 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.
To configure the networking settings:
1. Click All Devices > I/O Modules > View Details > Settings > Network or Devices > I/O Modules > View Details >
Settings > Network.
2. In the IPv4 Settings section, select Enable IPv4.
