On Saturday Dec 4th from 8:00 to 18:00 CET NASDAQ OMX will perform maintenance work on the co-location cabinets at NASDAQ OMX Data Center at Lunda. The maintenance affects only colo cabinets, regardless the trading system. The task implies the installation of power meters for power monitoring reason and therefore every power cord needs to be replaced. The affected co-location customers will experience down-time on their cabinets during that day. Each affected co-location customer is responsible to take down their own equipment before and bring it up when the work is done. Further, all affected co-location customers need to contact their network/Extranet provider to inform them of the event. Please get back to NASDAQ OMX with a reply no later than Monday Nov 1st, to confirm if you are comfortable or if you have any issue with the installation date and to appoint a contact person for cooperation during the maintenance. Please email your reply to afsaneh.rezaie@nasdaqomx.com.
