There are various ways to gain access to the ECX Fabric Portal as a new customer.
If you are already an Equinix customer, and have access to the Equinix Customer Portal (ECP), you can grant yourself immediate access to the ECX Fabric Portal.
Once you log in to the Customer Portal, go to the Gear icon in the top right corner, and click "My profile".
Once you are on your profile page, go to the Permissions tab, and scroll down to "Cloud Exchange Portal Permissions".
From there, you can check the tickboxes and give yourself access to ECX Portal.
If you are still unsuccessful in gaining access to the ECX Fabric Portal, please contact your CSM or the Equinix Help Desk for assistance.
