MIAX Pearl Options Exchange will refresh customer facing 10G ULL extranet edge switches on Friday, June 5, 2026, after the close of trading.

All MIAX Pearl Options Exchange Extranet edge switches will be replaced one to one with the new model, and all firm Cross Connects (CCs) will be moved to the same ports on the new switches. There are no changes required by firms for this hardware upgrade. There are no changes on the 1G LL shared Extranet.  

Following the upgrade, firms must conduct mandatory testing for all Pearl Options 10G ULL CCs.
 
Details on testing and verifications:

1. Testing will be held on Saturday, June 6, 2026, from 9:00 a.m. to 1:00 p.m. EDT.
2. Firms are required to perform the following verifications:
   1. Verify light levels and IP routing.
   2. Verify all 10G ULL CCs by logging into each subscribed application for each CC (i.e. establish application-level socket connections to MEO, MEI, FOI, CTD, etc., for all ports, across all CCs) and verify the login.
   3. Confirm heartbeat receipt for both the A & B market data feeds for all subscribed multicast feeds across each CC.
   4. After verifying connectivity, firms must inform MIAX Trading Operations at TradingOperations@miaxglobal.com.
