■ tertiary—Type and status of the tertiary timing signal
■ auto-upgrade—Status of the auto-upgrade parameter, which enables the
system to revert to a higher-priority timing source after switching to a
lower-priority timing source.
■ system operational—Status of the system
■ slot—Number of the slot in which the module resides
■ type—Type of module in the slot on the E120 and E320 routers
■ temperature—Temperature of the line module, SRP module, or SFM on the
E120 and E320 routers
■ processor temperature—Temperature of the line module or SRP module
■ processor temperature status—Temperature condition of the line module
■ normal—Temperature is in normal range
■ too hot—Module is too hot; system will go into thermal protection mode
if the temperature of any module exceeds 80° C
■ too cold—Module is too cold; system will go into thermal protection
mode if the temperature of any module drops below –5° C
■ IOA temperature—Temperature of the corresponding I/O module or IOA
■ IOA temperature status—Temperature condition of the corresponding I/O
module or IOA
■ normal—Temperature is in normal range
■ too hot—Module is too hot; system will go into thermal protection mode
if the temperature of any module exceeds 80° C
■ too cold—Module is too cold; system will go into thermal protection
mode if the temperature of any module drops below –5° C
■ processor temperature ranges—Displays the temperature ranges for the line
modules and SRP modules
■ IOA temperature ranges—Displays the temperature ranges for the I/O modules
on ERX7xx models, ERX14xx models, and the ERX310 router or IOAs on the
E120 and E320 routers
■ fabric temperature ranges—Displays the temperature ranges for the SRP modules
and SFMs on the E120 and E320 routers
■ Example 1—Displays the environment of an ERX7xx model
