If you plan to insert a new card, locate the entry for the card to be inserted and note the power it 
consumes. If this power is less than the figure given in Worst Case Redundant Power Available (the 
figure displayed in the show environment power-supply table command output), the card can be safely 
inserted. As long as the Worst Case Redundant Power Available is not zero, a PEM can be powered down 
for replacement without impact.

No alerts are issued if more cards are inserted than the PEMs can support. You are responsible for 
determining the power budget for the chassis before you change it. Exceeding the power budget can 
result in the PEM being overloaded and cards powering down due to insufficient available power.

Caveats describe unexpected behavior in Cisco IOS XR software. A severity 1 caveat is the most 
serious; a severity 2 caveat is less serious. This section lists resolved, open, relevant caveats and the 
software module upgrade (SMU)s that resolves these caveats in Release 3.2.6.

The following caveats from prior releases have been resolved in Cisco IOS XR Software Release 3.2.6. 

Brief Description: A loss of configuration can occur upon upgrade.

Conditions: The configuration loss can occur because of a broken security banner that has been 
configured in alternate configuration mode.

For example, if a customer has the following banner login config in the running-configuration:

banner login %
