A.9.5 Provisioning by NMC (Telnet) 
When placed in the CH20 with NMC, this card can be configured through any of the NMC interfaces, including Telnet, Web 
GUI and SNMP. NOTE: Termination and Pull-Up/Down must be set by DIP switch. 
<1> : Port Active - Use this item to enable or disable the line card. When disabled all transmission will be blocked and all 
the line card LED indicators will be Off. 
<2> : Serial Port Mode - This sets the electrical interface to RS-422 (4-wire), RS-485 (2-wire) or RS-232 (3 or 5-wire). 
<3> : Auto Laser Shutdown (ALS) - Enables or disables the ALS safety feature for the Optical port. 
<4> : Port Reset - This function will clear and reload the CPLD, effectively resetting the port. Data loss will occur when 
performing this reset. Use with care. 
<5> : Set to Default - This action will return the Serial card to factory default settings. 
<D> : Go to Line Card Status menu - If an SFP is installed for optical, the information can be viewed here. See next page.. 
<N> : Go to the Remote menu - This device supports remote in-band management via Embedded Operations Channel.
