Hi Linz2801,
Thank you for your question. There are several GSA Schedules that have Aruba products on them. You can find them by going to www.gsaadvantage.gov and searching for Aruba in the products search bar.
In regards to E-Rate, are you asking if Aruba is on a Preferred Master Contract as designated by the Bureau? As of today, Dec 22, 2014; the Wireline Competition Bureau has not yet designated any contracts as a Preferred Master Contract, and will not likely do so until the FY2016 Application Window.
However, USAC does have guidelines on applicants using State Master Contracts; which can be found at http://www.usac.org/sl/applicants/step03/state-master-contracts.aspx.
Please let me know if you need any additional information.
Thank you!
Dan
