The adapter base unit supports a pair of adapters. The adapter base unit has
connections for two power feeds, four Ethernet ports, and two adapters on the
front of the unit, and one I/O base connector on the right-hand side of the unit.
The connections for the adapters are commonly referred to as adapter slots.
To mount the 1715-A2A adapter base unit, follow these steps.
1. Place the 1715-A2A adapter base unit onto the DIN rails and position
them toward the left, leaving space for the I/O base units to the right.
2. Secure the adapter base unit onto the DIN rails by sliding the retaining
lever (below the base unit) to the left, as far as it goes, until it latches in
the locked position.
