On Saturday, March 11, 2006, CME plans to migrate its production mainframe computer to new hardware at a new physical location. This transition will be transparent to firms. In particular, the IP address by which firms connect to CME for MQM messaging and 3270 terminal access will not change.

To ensure that there are no issues associated with this transition, we will provide firms and service providers with an opportunity to verify, in advance of the transition date, that their systems will connect to the new hardware. Testing is voluntary and will be conducted on Saturday, February 25, 2006, from 8:30 a.m. to 11:30 a.m. CST. 

Testing Components:

• MQM Connectivity: Firms can send a trade via TREX into their production channel to clearing.
• Access to 3270: Firms can log in to 3270 session access TES application and review their trades.

Any test trades submitted on Saturday, February 25, 2006 date will be purged from the system and will not impact production. After testing is complete, firms are requested to contact CME Clearing Services at (312) 207-2525 to verify that it was successful.

For questions or concerns, please contact CCS at (312) 207-2525 or via email atccs@cme.com.

Thank you
