• Refresh Inventory

You must have the device conguration privileges to set up network IOMs and perform conguration tasks on them.

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.

For Port Information, when you enable auto-negotiation, peer devices exchange capabilities such as speed and settle on mutually

acceptable conguration. However, when the auto-negotiation is disabled, the peer devices may not exchange capabilities. Hence, it is

recommended that the conguration on both peer devices is identical.

The guidelines for auto-negotiation process are as follows:

• MX9116n, MX7116n, and MX5108n IOMs support only 25G speeds on server facing ports.

• By default, auto-negotiation is enabled on server facing 25G ports, as mandated by the IEEE 802.3 standard.

• You can enable or disable auto-negotiation, but cannot congure speed on server facing ports.

• When auto-negotiation is enabled, Ethernet switches display speed capability of only 25G.

Conguring IOM settings

If you have the IOM device conguration privilege, you can congure the following settings for the Fabric Expander and Ethernet Pass-

Through IOMs:

• Network

• Root password

• SNMP

• Time

You must have the network administrator privilege to congure the public management IP for the IOMs. The public IP facilitates use of the

IOM Command Line Interface (CLI) to congure and troubleshoot the IOMs.
