Installing the AGM
Figure 2-2 Installing the AGM in the Chassis
Step 6
Pivot the two module ejector levers out away from the faceplate.
Step 7 Carefully slide the AGM into the slot until the notches on both ejector levers engage the chassis sides.
Step 8 Using the thumb and forefinger of each hand, simultaneously pivot in both ejector levers to fully seat
the AGM in the backplane connector.
Caution Always use the ejector levers when installing or removing the AGM. A module that is partially seated
in the backplane will cause the system to halt and reset. Ensure that the ejectors are locked when the
module is in the slot.
Step 9 Tighten the captive installation screws on each end of the AGM faceplate.
Hot-Swapping Features
Although you can hot swap the AGM without powering down the switch, you cannot hot swap the
interface modules.
Caution Hot swapping a VIC, WIC, or VWIC from the AGM could damage the module. Their installation
requires removing the AGM from the chassis.
When you remove or insert the AGM while the switch is powered on and operating, the system does the
following:
1. Scans the backplane for configuration changes.
2. Initializes all newly inserted AGM, notes any removed modules, and places them in the
administratively shutdown state.
3. Places any previously configured interfaces on the AGM back to the state they were in when they
were removed. Any newly inserted interfaces are put in the administratively shutdown state, as if
they were present (but not configured) at boot time.
