Juniper Networks J-series Services Router J2320 - Manual (Page 88)

■ Local and remote loopback diagnostics
■ ITU-T G.991.2, ITU-T G.994.1, and ITU-T G.997.1 standards compliance
NOTE: Payload loopback functionality is not supported on ATM-over-SHDSL interfaces.
For pinouts of cable connectors for G.SHDSL PIMs, see “ADSL and G.SHDSL RJ-11
Connector Pinout” on page 238.
To install or remove a PIM, see “Replacing a PIM” on page 172.
The G.SHDSL PIM has two LEDs to indicate the status of the PIM and its ports.
Table 33 on page 66 describes the meaning of the LED states.

Avaya VoIP Modules
The Avaya VoIP modules are installed in a J-series chassis like Physical Interface
Modules (PIMs), but they are controlled by the Avaya Communication Manager
software rather than the JUNOS software.
CAUTION: PIMs and VoIP modules are not hot-swappable. You must power off the
Services Router before removing or inserting a PIM or VoIP module. Ensure that the
PIMs and VoIP modules are installed in the router chassis before booting up the
system.
CAUTION: The grounding cable for J-series routers must be, at minimum, 14 AWG
cable. For more information, see “Chassis Grounding” on page 123.
