2. Select the Update Now option to update the firmware immediately or Schedule Later to update the firmware on the chosen date
and time.
NOTE: If the system displays the local clock on the Time Configuration page even after you configured the NTP servers,
reconfigure the NTP servers.
NOTE: During firmware update, when the active MM reboots and the standby MM is active, some messages on the Execution
Details page for the firmware update are not displayed. The messages are not displayed owing to synchronization issues.
NOTE: During the OME–Modular firmware update, multiple users can upload the OME–Modular DUP using any interface.
However, a warning message may be displayed after the firmware update job is initiated.
NOTE: For nondefault VLAN, the management IPv6 IP of MX9116n or MX5108n IOMs is unreachable if, the DHCP V6
configuration in ToR switch does not have the IPV6 default gateway.
The number of IOMs that can be updated differs based on the IOM versions. The following table displays the number of IOMs that can
be updated at a time.
Table 23. IOM Firmware update matrix
IOM Version OME-M Version No. of IOMs
10.5.0.5 1.10.20 or later 4
10.5.0.7 1.20.00 or later 6
10.5.1.6 1.20.10 or later 6
10.5.2.3 1.30.00 and later No restrictions
You must group the IOMs for firmware update depending on the type of IOM. The following table displays an example of grouping 12
IOMs for firmware update.

Once all IOMs are updated to 10.5.2.4 stack, network IOMs display two software components for update. The available options are:
● Dell EMC Networking SmartFabric OS10
● Dell EMC Networking ONIE Firmware
Limitations for ONIE firmware update are:
● ONIE firmware update option is available only if the OS10 version is 10.5.2.3 or later.
● When you select the network IOM that is part of a fabric for ONIE update, other nodes in the fabric are updated automatically.
● If you insert an old version of IOM, the ONIE firmware cannot be updated before updating OS10 to 10.5.2.4 version.
NOTE: ONIE component firmware is not updated due to the issue of system not booting into ONIE, when GRUB menu is
displayed with serial control character. This issue is addressed in 3.35.1.1-15 ONIE firmware version. If ONIE update fails or
encounters ONIE booting issue, retry the ONIE component firmware update.
