WARNING:

Do not power down a Switch Node carrier to replace a circuit pack.

!

WARNING:

In duplicated PNC configurations, one DS1 converter complex in the fiber-link 
serves as the active and the second DS1 converter complex serves as the 
standby. Each DS1 Converter complex consists of two TN574 boards or two 
TN1654 boards. A TN574 cannot be combined with a TN1654 in the same DS1 
converter complex. It is also required that all four DS1 converter boards and 
interconnecting facilities that serve an PN be of the same type. Note, however, 
that TN574 and TN1654 boards can coexist within the same system, they just 
cannot be in the same fiber-link.

!

WARNING:

The two DS1 converter boards, TN1654 and TN574, use unique “Y” cables that 
are incompatible with each other.

!

WARNING:

A TN573B (or higher-suffixed) board must be used when connecting a SNI board 
to a TN1654 DS1 Converter board.

Enter change circuit-packs 

cabinet #. Update the screen to 

show that TN1654 boards are now 

being used instead of TN574 boards. 

Also update the connected SNI, if 

applicable, to suffix B.

Cabinet # represents the cabinet associated with a 

DS1 converter board. The change circuit-packs 

screen needs to be updated for both DS1 converter 

boards. Also, if needed, re-add translations for 

connected EI boards.

Enter add fiber-link fiber# to 

re-add the fiber-link using TN1654 DS1 

converter circuit packs. 

Fiber# represents the fiber-link number associated 

with the TN574 DS1 converter complex that is being 

upgraded to a TN1654 DS1 converter complex
