Terminal Description
+BAT A This terminal and -BAT A serve as DC power input connections for a DC supply installed as
the primary or main supply. (DC systems only)
+BAT B This terminal and -BAT B serve as DC power input connections for a DC power supply
installed as the redundant or backup power module. (DC systems only)

ALARM: MINOR NO Minor alarm condition, normally open contact*. This terminal electrically meets the MINOR
COM terminal when the system exhibits a minor fault or when the system has no power.
ALARM: MINOR COM Minor alarm, common.* This terminal electrically meets the MINOR NO terminal when the
system exhibits a minor fault or the system has no power. Else this terminal will electrically
connect to MINOR NC.
ALARM: MINOR NC Minor alarm condition; normally closed contact*. This terminal electrically meets the MINOR
COM terminal when the system has power and there is no minor fault exhibited. During a
minor alarm, this terminal is electrically isolated.
ALARM: MAJOR NO Major alarm condition, normally open contact*. This terminal electrically meets the MAJOR
COM terminal when the system exhibits a major fault or when the system has no power.
ALARM: MAJOR COM Major alarm, common.* This terminal electrically meets the MAJOR NO terminal when the
system exhibits a major fault or the system has no power. Else this terminal will electrically
connect to MAJOR NC.
ALARM: MAJOR NC Major alarm condition; normally closed contact*. This terminal electrically meets the MAJOR
COM terminal when the system has no power and there is no major fault exhibited. During
a major alarm, this terminal is electrically isolated.
* When the shelf is not on (does not have power), all relays default to their alarm positions. Normally
open contacts are closed and normally closed contacts are open.
The NORMAL, ALARM:MINOR and ALARM:MAJOR are all mutually exclusive. If there is a minor or
major alarm condition present, the NORMAL indicator light on the NetXpress chassis is off, and the
MINOR (yellow) or MAJOR (red) indicator light is on, showing the degree of fault.
3.10.3 MIU-201 Connections and Wiring
The MIU-201 is the module interface unit for the NIM-1 module. All hardware networking connections
terminate at the MIU. The MIU has connections for
● Two T1 or E1 networks.
● Ethernet WAN, LAN, and MGMT (management) connections.
● Network timing input and output.
