These procedures apply to all CIXP customers and their sub-contractors. The definitive list of customers and their authorized sub-contractors is kept by the CIXP manager (EDMS: 1208875 and Service Now KB0002788) and is distributed internally to various distribution lists and to the CERN Access Registration Service.

• Customers must send all access requests to cixp-access@cern.ch, stating:
  1.  First Name, Surname & company
  2. Date & Time & expected duration of the intervention
  3. Which technical area needs to be accessed (i.e. room and rack ID)
  4. Brief description of work to be done
• The email will generate a ticket for the Access Registration service. Therefore, please only send access requests to this address! For contractual, technical or general questions concerning the CIXP, use cixp-support@cern.ch.
• When the request is granted, CIXP informs the customer and provides further instructions:
  1. If access is during working hours (08:00-18:00), the access card must be picked up at the reception of Building 33 (visitor card service). The ID check is done by the reception.
  2. Outside working hours, the access card will have been left with the guard at the main gate (Entrance B). A security agent will then accompany the engineer to 513 after their credentials have been validated.
• In the event of an emergency access request made outside working hours, and there has not been enough time to prepare an access card, the customer shall go directly to the guard at the main entrance (Gate B). The guard will check that the company is on the official CIXP access list (EDMS: 1208875) and a security agent will then accompany the engineer to the computer centre and their equipment.   
• During working hours, once at the computer centre (513), the engineer should call +41 22 767 1717 to gain access to the CIXP technical area.

Note: The Registration Forms for Personnel of Contractors and the declaration for the French work inspection ("Déclaration Préalable d'Intervention à l'Inspection du Travail du Lieu d'Intervention") do not need to be filled in. These documents are required by subcontractors coming on-site to execute work under a CERN mandate. In the case of the CIXP, customers are working on their own equipment and are entirely responsible for their own contractors.
