Chapter 1 Introduction
1.7 GSW/SNMP (Aggregate Switch)
FRM220A must be ordered with an aggregate Card. The card is placed in the rear of the chassis and provides
backplane connection to each card slot. Management is accomplished via Ethernet and any standard SNMP
network management software that supports MIB-II. The WEB GUI based interface provides an easy method for
the user to operate and monitor the whole system. Almost all line cards support remote in-band configuration when
paired with the same type FRM220A stand-alone in-band converter.

1.9 Installing the GSW/SNMP
The rear of the FRM220A provides slots for the dual power supplies, the two cooling fans and the GSW/SNMP
Gigabit Ethernet Aggregate Card. This card may or may not be factory installed. If installing, align the card with the
side rails and slide in until the edge connectors just make contact with the back plane. Press the card in firmly using
thumbs at both the left and right hand side of the card with equal pressure. Screw in the holding screws and just
barely tighten (do NOT over tighten). The card will not come out on its own; it will require significant pulling force to
unseat.
