 The BA213 power supply uses an IEC C16 high-temperature 15A power inlet connector, which is not compatible with the more common IEC C13 power cables typically used with computers as the keying feature prevents insertion of C13 cable ends. An IEC C15 end is required, such cables are commonly used with carrier-grade network equipment and are readily available.

 Pedestal mounted BA213 enclosures include wheels, which allow the enclosure to be rolled around. These wheels are not ''caster wheels'', they are fixed roller-type wheels, which makes turning difficult. This feature does increase appropriateness for [[VAX jousting]] applications.
