 You will need another UCM to upgrade the UCM firmware
If you do not have another UCM, you can send yours to Cytech, we will upgrade it and just charge the transport cost

 I have two units of UCM but unfortunately the firmware version are 5.154 and below.  Can it works?

 With UCM less than 5.178 if there is any error in the firmware upgrade process the module being upgraded will not work until the firmware is upgraded properly
With UCM 5.178 and above the UCM will be able to repeat the firmware upgrade even if there was an error
As you have two UCMs it may be worth the risk to upgrade  the UCm to 5.200 and then swap the UCMs and use the upgraded UCM to upgrade the first one to 5.200
If there is an error, send the UCM to us for  upgrading
