Reset Push Button

redundant line card. When used in conjunction with the card’s switchover and
secondary LEDs and the AUTO DIP switch setting, this push button allows you
to effectively maintain or troubleshoot the PRIMARY link connection.

the RESET push button with the tip of a pointed object. Pushing and holding the
RESET push button has no effect. It is the act of pressing the push button that
causes a reset.

following effects:
If the AUTO switch is UP The active port automatically reverts to
and the RED switch is UP. PRIMARY when the primary link is reestab-
lished. Pressing the RESET switch clears
the SW LED.
If the AUTO switch is DOWN The active port does not automatically revert
and the RED switch is UP. to PRIMARY when the primary link is
reestablished. Pressing the RESET switch
clears the SW and SEC LEDs and forces the
PRIMARY port to be the active port. If the
secondary link is disabled, it will revert
to PRIMARY if the PRIMARY port has a
good link.
If there is a link only on the SECONDARY
port, then the SW and SEC LEDs will remain
lit. Pressing the RESET switch will have no
effect.

(NSM). The RESET push button toggles the
active link between the PRIMARY and
SECONDARY ports.
