See "Troubleshooting" on page 77 for information on the system's LEDs.
NOTE: In the fan tray for the E320 Broadband Services Router, four of the
eight fans turn on immediately upon initial power-up and the other four fans
turn on after a delay of 10 seconds.
If you need to power down or remove the SRP module, first enter the halt command to
temporarily suspend the system's operation. See JunosE System Basics Configuration
Guide, Chapter 5, Managing the System for more information.
CAUTION: If you do not use the halt command before removing or powering
down an SRP module, the system's NVS card might become corrupted.
If you shut down the system improperly, it runs an investigation of the file allocation table
(FAT) the next time it reboots.
If you have problems powering up the system, see "Troubleshooting" on page 77 for help.
If the system boots properly, see "Accessing E Series Routers" on page 59.
