Pac is included in the Solution Pac CD-Rom. For Network Management or multiple computer shutdowns an
optional network card must be purchased.
◗ The Dry Contact Port is used for basic signaling or for protection of IT systems like IBM iSeries (formerly
AS400) and more.
◗ The slot is compatible with any MGE UPS SYSTEMS, INC. communication card (check www.mgeups.com
web site for the complete list of compatible cards)
