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.
