The suffix belongs in the purchase description

Ask the supplier to identify the proposed code explicitly. Do not invent a license entitlement or functional upgrade from the -2A abbreviation alone.

Check the network before moving the cables
Record port assignments, addressing, approved configuration and firmware expectations. Each of the twelve copper interfaces is Gigabit-capable, but the actual connection also depends on the endpoint and cabling. Plan which port connects upstream and which ports serve local equipment. Avoid approving a spare solely because it has enough RJ45 sockets.
Review the physical replacement conditions
The standard-temperature device is rated for 0 to +60 °C and uses a PC-ABS IP30 housing. The manufacturer lists two 12–24 V DC inputs and 11 W consumption. Compare the supply arrangement and access to terminals with the installation instructions. A 73 mm body width is only the device dimension; leave room for connectors and service work.
