2.8 Installation
2.6.1 Line Card Installation
The Line Cards for the FRM220 are Fiber Media Converter Cards which slide into the FRM220 chassis, and
interface with the pack panel "main board". The back panel provides a connection to the converter cards for power
and serial control.
The media converter cards are designed to be "hot" swappable, meaning the FRM220 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 effect the operation of other converter cards.
Removal of a converter card is accomplished by loosening the one (1) captive screw (upper) 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.

2.6.2 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 20, may contain any other
FRM220 In-band Managed fiber media converter card.
Figure 2-8 NMC removal/replacement in slot number 1
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.
