Upgrading the Switch Fabric
Checking the Replacement Alarm Card
To check the replacement alarm card installation, follow these steps:
Step 1 Verify that each of the following conditions is true:
• The replacement alarm card is fully seated in its slot and both captive screws are tightened.
• If an external alarm cable is connected to the alarm card, the connector is completely seated and
held in place by the hold-down hardware.
Step 2 Visually check the LEDs on the two alarm cards. When the system is operating correctly, the following
LED conditions should be true:
• All three system alarm LEDs should be off.
• The alarm card status LED labeled ENABLED should be on; the LED labeled FAIL should be
off.
• The LED labeled ENABLED for each CSC and SFC in the switch fabric card cage should be
on; the LED labeled FAIL should be off.
If the alarm card does not initialize properly, refer to the Cisco 12016, Cisco 12416, and Cisco 12816
Router Installation and Configuration Guide for additional information and installation troubleshooting
procedures. If you are still unable to resolve the problem, contact your Cisco service representative for
assistance.
Upgrading the Switch Fabric
The switch fabric on the Cisco 12016 and the Cisco 12416 Routers can be upgraded in the field. This
allows you to upgrade a 2.5- or 10-Gbps switch fabric to a higher performance switch fabric.
Cisco 12016 Routers can be upgraded from a 2.5-Gbps switch fabric to a 10- or 40-Gbps switch fabric.
Cisco 12416 Routers can be upgraded from a 10-Gbps switch fabric to a 40-Gbps switch fabric. Table 1
lists the Cisco router model numbers, their corresponding switch fabric speed, and the available upgrade
path for each router model.
