LNet Connectivity Procedures
Customer Requirements
LNet Customers must meet the following requirements:
...
- Please note that floor and suite location must be included on the Access Request Form or Schedule 2.
- Although CME Group facilitates the cross connect requests within the hosting facility, it is the customer’s responsibility to complete and/or approve any vendor agreements that may be applicable.
- Provide two routers or Layer 3 switches that will terminate each 1 or 10 Gbps, single-mode fiber cross-connect.
- The point-to-point IP address must be configured on the interface closest to CME Group device.
- CME Group recommends that the customer checks the Signal/Light levels at the time of turn up in order to attenuate levels to protect equipment.
- Verify connectivity requirements with the respective vendor.
- Avoid using media converters.
- The customer’s SFP or GBIC must be compatible with long wavelength/long haul SFPs.
- Please note there are specific prerequisites for firms interested in becoming a CME Group-approved 3rd party vendor that provides proximity services. Please contact Global Account Management (GAM) for more information.
