Management Features
The FRM220-Eoe1/G has one on-board 2 pole DIP Switch which can be
used to configure the device timing source (recovery or internal) and the
framing mode. When placed in a stand-alone chassis with DB9 console
port, these devices support a text based serial terminal with an easy to use
menu system for configuration. When placed in a managed chassis, the
card is configured and monitored through the chassis NMC (network
management controller) via console, Telnet, Web HTTP or SNMP.

1
OFF
Sets the E1 clock source to Internal Oscillator
ON*
Sets the E1 clock source to receive signal recovery (Default)

Important: The switches are set to default at factory. It is recommended
to not change the default settings.
Notice: All of these settings are ignored if the card is placed in the
FRM220-CH20 with NMC/SNMP or FRM220-CH20A GSW/SNMP
management. The card will follow the settings done via the chassis
management. (Refer to NMC or GSW/SNMP operation manual for details
on managing all cards.)
