Description
NOTE
When inter-subrack protection is
configured, the ETH3 interface cannot
be used for the communication between
the master and slave subracks.
Connects a network cable to a

CRPC or ROP board to achieve
communication with the CRPC
or ROP board.
See Network Management for more
information.
Outputs single-subrack or
multi-subrack alarms to the cabinet
indicator interface to light the
corresponding alarm indicators on
the cabinet.
NOTICE
The LAMP interfaces on the EFI board
provide 5 V power, it is only used for
the indicators on a cabinet. It cannot
connect to an RJ45 cable intended for
the NM_ETH, ETH, ALMO, or CLK
interface; otherwise, the EFI board, the
connected test instrument, or the
equipment will be damaged.
For information about the interface
cables, see 2.6.1 Cabinet Alarm
Indicator Cable.
Alarm outputs are sent to the

DC power distribution cabinet
through the output interface and
the cascading interface. You can
configure it to be the other
outputs to implement integrated
display of alarms. The alarm
outputs are controlled by the
internal relay contact. When the
relay contact is closed, the
resistance of each ALMO
interface is less than 1 ohm.
When the relay contact is open,
the resistance of each ALMO
interface is an infinite number.
The definitions for the pins of

the ALMO1 and ALMO2
interfaces are the same. The two
interfaces are used for
output/cascading, respectively.
