APS 1+1 (Card and Line Redundancy)
APS Front Card Displays
The front card LED functions are listed in Table 25-4.
APS 1+1 LED Displays
The back cards used for APS 1+1 with front card redundancy have an LED which indicates whether the
back card can be pulled out for service replacement.
For example, all the lines on the card except one may be working properly and therefore the card needs
to be replaced. The back card LED functions are listed in Table 25-5.
Note
In the APS 1+1 configuration, when the primary card is active and the protection line is active, LEDs
on both back cards are green. The LED of the secondary is green because that back card is carrying
traffic. The LED of the primary back card is green, because that is in the physical path of the front
card in receiving traffic from the protection line. When the back card LED is green do not pull out
the back card, because it will disrupt traffic. When the LED is yellow it is OK to pull out the back
card, but it should be put back as soon as possible, because the card is needed in the event of a
switchover.
APS 1+1 (Card and Line Redundancy)
The APS 1+1 feature requires two BXM front cards, an APS redundant frame assembly, and two
redundant type BXM back cards. The two redundant BXM back cards are plugged into the APS
redundant frame assembly as shown in Figure 25-4. The following are the types of available back cards:
The following are the types of redundant back card and backplane sets:
•
