Axxius 800 - Release 2.2 17-7
Low Speed Protection Card
Card Configuration
Use the following steps to set up a Protected System.
1. Install a Relay card in the Axxius Relay slot.
2. Set the jumpers on the Quad T1 cards to route the signal to the wire-wrap pins,
see Jumper Settings on page 14-8 for detailed instructions.
3. Prewire the chassis for Quad T1 cards (wire-wrap pins).
Note: It is imperative that the slot designated for the Quad T1 backup
card have NO wire-wrap connections.
4. Install the Backup Quad T1 card into the designated service card slot (no
prewire).
5. Install Quad T1 cards that are to be protected into the prewired card slots.
Note: These QT1 cards can be in any slot, as well as other card types. Also
removal and/or replacement of any of these service cards will not effect
service to cards in adjacent slots.
Perform the following CLI commands to configure the system for protection.
With the above steps protection is now provided for the specified cards. Any
single protected card can be pulled from its slot with only minimal interruption
to service. Since protection is on a 1xN basis once protection is provided for a
failed port other ports cannot be protected at the same time.
