NMC (SNMP)
The
FRM220-CH04A
must be ordered with an NMC Card. The card is placed in the far left, upper
card slot. Management is accomplished either via local control on the asynchronous RS-232 port with
an ASCII terminal or 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 stand-alone in-band converter.
NMC Card Installation
Slot number 1 of the chassis is reserved for the Network Management Controller (NMC). The NMC
card provides the full network management features. When the NMC is installed, the rack and all line
cards become manageable by industry standard SNMP protocol. (Please refer to Chapter 3 for more
information on the operation of the network management features). The remaining slots, numbered 2
through 4, may contain any other FRM220 Series In-band Managed fiber media converter card.

IMPORTANT:
In the FRM220 In-Band Managed Rack, slot number1 must contain an NMC card. In a
chassis where non-managed line cards are employed (cards that use DIP switch settings), slot
number 1 may then be used for a non-managed media converter line card.
Line Card Installation
The Line Cards for the FRM220 Series are Fiber Media Converter Cards which slide into CH04A
chassis, and interface with the "main board".
The media converter cards are designed to be "hot" swappable, meaning CH04A chassis need not
be powered off in order to remove or replace a card. Removal and installation of converter cards with
the rack chassis under power will not affect the operation of other converter cards.
Removal of a converter card is accomplished by loosening the one (1) captive screw (right) and
then pulling the card straight out of the chassis with the same screw. Replace the card by reversing the
procedure, align in the slot groove and gently seat the card, retightening the captive screw.
