Can you tell me how you are doing the update?
Are you using a USB stick?
Have you tried to download the previous firmware and see if it accepts the file?
Well, the normal procedures are as follows:
Download the .tgz package to a known directory or USB device.
Open the Storage System Manager Web User Interface (UI) on a system connected to the SS4200-E
Connect and login to the SS4200-E you wish to upgrade the software
From the Web UI Home page select the "Settings" tab
From the Settings page, select "Upgrade"
From the Upgrade page, select the "Copy Upgrade File" checkbox and browse to the saved EMCNTG-188.8.131.52736.tgz file and select "Next".
When the Upgrade Device Software page appears, verify the version, and if correct, select "Next" to proceed with the upgrade.
On the following page, select "Apply" to start the upgrade processs. The system software upgrade will proceed.
There was an issue before:
If a USB drive running NTFS is connected to the EMC Storage, the content of that drive will be read-only. The Intel® Entry Storage System SS4200-E device only supports one partition for USB disk drives and eSATA disk drives.
Let me know more information
Aside from the "What is this, 1996?" lameness of having to use a particular browser -- not to mention requiring IE for a supposedly cross-platform product -- I am trying the update with IE under Parallels. The upgrade has been running for 30 minutes or so. The firmware file is only 40 MB. Is there any way to monitor the process?
