Interface Card and Interface Module Manual.
Note:
The SIC slots on the AR 28-11/28-12/28-13/28-14 do not support the
SIC-1FEA/SIC-1ETH card, but two fixed Ethernet interfaces are available on these
models.
The AR 28-10 supports only one SIC-1FEA/SIC-1ETH card.
Interface cards and modules may be available with multiple versions as the result of
hardware upgrade. To identify the version of a card or module, read the label, for
example, RT-4FXO/RT-4FXO-V2, on the card or module.
An interface card (including the silkscreen on its panel) looks the same before and
after hardware upgrade. Upgraded interface cards are functionally backward
compatible and some can even provide enhancements. To support the upgraded
hardware, you need to upgrade host software.
