Are they branded with Visa, Mastercard, or Discover? If they are branded and you have a contract with that brand, you will have to perform the cash advance in accordance with your vendor contract.
It looks like they are branded Visa. So if you process Visa cash advances, you will need to conduct the cash advnaces on these cards as well.

Can I get cash back at any bank or ATM?
You can make cash withdrawals at any Visa-member bank. You get one free cash withdrawal from a bank teller after each deposit. After that, withdrawals from a bank teller are $5.00 each. You must show the bank teller a government-approved photo identification to get cash. The bank teller should not send you to an ATM.
