1.    Introduction

Following the replacement of the Cash Market Data Access Layer Switches (A-side) in the Equinix FR2 co-location (Colo 2.0) facility on 20 April 2024 (Xetra Circular 009/24), Deutsche Börse will replace the Cash Market Data Access Layer Switches (B-Side) on 28 September 2024. The dissemination of technical heartbeats in production and simulation market data via the EOBI, EMDI and MDI interfaces on the B-Side will be disrupted during the timeframe of the tech refresh and will continue afterwards as usual.

To ensure a smooth transition to the new switches and reduce the amount of impact on participants to an absolute minimum, the names of the switches (RFRA3531 and RFRA3532) and the current assignment of the ports to participant installations will remain unchanged.
 

2.    Required action
 
After the replacement, participants are strongly recommended to verify their connectivity to the new switches (e.g.) by confirming the receipt of technical heartbeats from the T7 production environment or the receipt of market data from the T7 simulation environment. 

Deutsche Börse will provide a support window on Saturday, 28 September 2024 between 14:00 and 16:00 CEST. 

In the event of any unforeseen issues, participants will be able to contact their Technical Key Account Manager via their VIP number or cts@deutsche-boerse.com during the support window.
