Provision of Grace Period Before
Route Processor Shutdown from
Ejector Lever
Earlier, unlatching the ejector lever from the latch lock immediately would trigger a graceful shutdown of the
Route Processor if the card is in the operational state. However, after enabling this feature, the RP card has a
grace period of 15 seconds before shutdown.
If the ejector lever is latched back within this grace period, then the card returns to the operational state. This
feature, therefore, provides the option of closing the ejector lever without triggering a shutdown. This feature
is especially useful when an ejector lever is accidentally unlatched.
This feature is supported only on a route processor card.
If the ejector is unlatched when card is in a status other than operational state then the grace period feature
will not be supported.
Caution When you enable this feature, do not remove the RP during the 15-second grace period. Remove the RP only
in either of the following two ways:
• Allow the RP to shut down after the 15-second grace period, then remove the RP.
• Close the ejector lever within the 15-second grace period, then remove the RP gracefully (shutdown the

Release Information
Release 7.3.1
Hardware Installation Guide for Cisco 8800 Series Routers
Feature Description
Unlatching the ejector lever of the
Route Processor (RP) card that is
in operational state, triggered a
graceful shutdown of the RP.
With this release, the RP card is
enabled with a grace period of 15
seconds before it shuts down. In the
event the ejector lever is unlatched,
or for any other reason, you have
15 seconds to relatch the ejector
lever and return the RP back to its
operational state.
The hw-module ejector close wait
command is introduced for this
feature.
