Hardware Overview
Backup LEDs
The second LED in each column reports the status of the backup module, if a
backup module is installed. The LED in the first column corresponds to the
backup module in slot one, and the LED in the second column corresponds
to the module in slot two. The status LEDs for backup modules can display
one of the following:
■ No light—A backup module has not been installed and activated.
■ Red—The backup module has been activated and configured, but a valid
physical connection has not been made. A red LED may also indicate that
the backup interface has received a WAN alarm or has failed a self-test.
■ Solid green—The module is ready to be used if a connection that it backs
up should fail. For ISDN BRI backup modules, a solid green light further
indicates that the module has completed negotiation with the switch.
■ Yellow—A self-test is in process.
■ Flashing green—The backup link is currently active.
Tx and Rx LEDs
The Tx and Rx LEDs signal WAN activity across the corresponding interface’s
link. The third (Tx) LED in each column signals that the interface is transmit-
ting data, and the fourth (Rx) LED indicates that the interface is receiving data.
Tx and Rx LEDs signal the following:
■ Off—The link is inactive.
■ Green—Data is being transferred across the WAN or backup interface.
Slot 3 LEDs
The ProCurve Secure Router 7203dl includes a third column of LEDs that
represent the wide module. Unlike the other columns of LEDs, this column
includes only three LEDs. (See Figure 1-18.)
