Product Firmware Version Restrictions

日本語版はこちら

Overview

Each Cisco Meraki product has a minimum firmware version that it can run which may not always match up with what the dashboard network is configured for. Therefore the node will run the minimum firmware it is capable of running, which may be higher than the network configured firmware. This article will list each currently supported product and the minimum firmware they can run. 

Additionally, some devices which have reached end-of-sale may have maximum support firmware versions. The node will not be able to run firmware versions newer or higher than the indicated maximum version.

Note: Meraki recommends checking the Organization > Firmware Upgrades page to verify which firmware version your network is running, rather than referring to the available firmware messages that may be presented for each individual device. The Firmware Upgrades page is the best method to ensure you have the most recent build.

Warning: Please ensure that MR44 is connected to an 802.3at-capable (PoE+) switch/power injector during the initial installation OR ensure that the network the MR44 is added to is set to MR 27.6 or newer firmware.

This is because the default MR44 firmware image has support for the low-power mode, however, MR 27.5/27.5.1 or lower firmware does not have low power mode support. Using 802.3af switch/power injector with MR44 set to 27.5/27.5.1 or lower firmware might result in unexpected behaviors including but not limited to reboots or degraded performance. 

Due to the reasons stated above, please do not downgrade the network with MR44 APs to 27.5/27.5.1 or lower firmware if they are being powered on by 802.3af (PoE) switch/power injector.

* Z1s, MX60/Ws, MX80s and MX90s cannot upgrade to MX 15 firmware, or any newer major release versions. If networks containing these devices are configured to run newer firmware revisions, they will run the newest MX 14 maintenance release instead.  

** The Z3 once updated to MX 14.31 or 15.8 and beyond will not be able to run any older firmware than MX 14.31 or 15.8

*** MX64/W, MX65/W, MX84, and MX100 cannot upgrade to MX 18.2 firmware, or any newer major release versions. If networks containing these devices are configured to run newer firmware revisions, they will run the newest MX 18.1 maintenance release instead.
