To troubleshoot problems on a QFX10002, use the Juniper Junos OS command-line
interface (CLI), and the LEDs on the field -replaceable unit (FRU) and the management
panel.
CLI—The CLI is the primary tool for controlling and troubleshooting hardware, Junos
OS, routing protocols, and network connectivity. CLI commands display information
from routing tables, information specific to routing protocols, and information about
network connectivity derived from the ping and traceroute utilities. For information
about using the CLI to troubleshoot the Junos OS, see the Junos OS software
documentation.
LEDs—When the switch detects an alarm condition, it lights the red or yellow status
alarm LED on the management panel. In addition, the individual fans and power supplies
also have status indicators.
JTAC—If you need assistance during troubleshooting, you can contact the Juniper
Networks Technical Assistance Center (JTAC) by using the Web or by telephone. If
you encounter software problems, or problems with hardware components not
discussed here, contact JTAC.
