Ericsson Redback Networks SmartEdge 1200 User Manual

Determining Hardware Status
5-6 SmartEdge 1200 Router Hardware Guide
Table 5-4 lists the facility LEDs, which provide status for the Ethernet management port.
Table 5-5 lists the synchronization and external timing LEDs, which indicate the status of any connected
external timing source.
Caution Risk of data loss. Do not remove a CF card from its slot while the CF ACTIVE LED is
blinking; you can lose data that is being transferred to the device if you enter the unmount
/md command (in exec mode) before the data transfer operation is complete. To reduce the
risk, you must wait until the CF ACTIVE LED is off; then enter the unmount /md command
to prepare the device for removal.
Caution Risk of equipment failure. Removing the CF card from its slot without first entering the
unmount /md command (in exec mode) can permanently damage the device and cause the
kernel to crash. To reduce the risk, always enter the unmount /md command before removing
a CF card.
