INITIATE A PROTECTION SWITCH
Summary: This procedure instructs the operator in the steps required to initiate a protection
switch for the various interface types in the system that are equipped with a protection
mechanism. The user may issue a Manual switch, Forced Switch, Lockout of protection, or
Enable a card for switching. Frame Relay Service cards do not support a protection mechanism
for Release 3.1 systems.
Prerequisites of issuing a switch request are:
• Card Admin Status must be UP.
• Cards must be configured in a protection group.
• Card APS Status must be Enabled.
• Card Protection Group must indicate a protecting card that meets the previous criteria.
• Both the working and protection card must have the same software and configuration
data so the same level of service may be provided if a switch occurs.
• User must have launched the Graphical User Interface and accessed the shelf level GUI
before attempting this procedure. Refer to DLP-705.
1. From the GUI main screen, select the node that will have the protection switch performed
on it by double clicking on it using the left mouse button. The shelf level GUI “Chassis
View” window will appear.
2. Select the Configuration pull down menu on the toolbar by clicking on it using the left
mouse button, or by hitting the Alt+N keys on the keyboard. Refer to Figure 771-1.
3. Select Protection Groups by clicking on it using the left mouse button or by hitting Alt+P
on the keyboard.
4. When the Protection Groups/Protection Switch window appears select the Protection
Switch box at the upper left side of the window.
5. Select the card to be switched using the left mouse button. Refer to Table 771-1 for valid
protection group configurations.
6. Select the protection switch type (Lock out, Manual, etc.) Refer to Table 771-2 for
protection switch definitions.
7. Select the Apply button at the bottom of the window to send the switch request.
8. To release the switch, select the working or protect card and select the Enable Auto Switch
followed by the Apply button.
Stop! You have completed this procedure.
