Status of fans.

nvs

Status and capacity of NVS and amount of space used.

power

Status of power feeds.

AC power

For ERX310 router only; status of power feeds.

srp redundancy

Availability of a redundant SRP module

slots: cards missing or offline.

Status of each slot:

  • online
  • standby
  • offline
  • empty

line redundancy

Number of redundancy groups installed:

  • width—Number of slots the redundant midplane covers
  • spare—Slot that contains a spare line module
  • primary—Slot that contains the primary line module

Configuration details for stateful line module switchover on E120 and E320 routers

  • high availability is configured on slots—Slot numbers of the pairs of primary and secondary line modules configured on a single chassis for stateful switchover.
  • high availability state is active on slots—Slot numbers of the pairs of primary and secondary line modules activated for stateful switchover.

temperature

Status of the system temperature

timing

Source of the timing signal:

  • primary—Type and status of the primary timing signal
  • secondary—Type and status of the secondary timing signal
  • 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 within the normal range
  • too hot—Module is too hot; system will go into thermal protection mode if the temperature of modules in any two slots exceed 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 within the normal range
  • too hot—Module is too hot; system will go into thermal protection mode if the temperature of modules in any two slots exceed 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

Temperature ranges for the line modules and SRP modules.
