Channelized OC3/STM1 Circuit Emulation PIC with SFP (M7i Router)

 

Software release

  • Junos OS Release 9.3 and later

Description

  • Four OC3/STM1 ports

  • Power requirement: 0.52 A @ 48 V (25 W)

LEDs

OK LED, one tricolor:

  • Off—PIC is offline and it is safe to remove it from the router.

  • Green—PIC is operating normally.

  • Yellow—PIC is initializing.

  • Red—PIC has an error or failure.

APP LED, one bicolor:

  • Off—Monitoring application is not running.

  • Green—Monitoring application is running under acceptable load.

One tricolor per port:

  • Off—Not enabled

  • Green—Online with no alarms or failures

  • Yellow—Online with alarms for remote failures

  • Red—Active with a local alarm; router has detected a failure
