Upgrading the Switch Fabric
Installing the External Alarm Display
To replace an external alarm display assembly, follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD sockets on
the front of the chassis or to a bare metal surface (see Figure 4 on page 9).
Step 2 Secure the replacement external alarm display assembly to the chassis with the two panel screws.
Step 3 Connect the cable coming out of the chassis to the alarm display assembly INPUT connector and secure
the two screws in the cable.
Step 4 Connect any cables that were attached to the ALARM A or ALARM B connectors.
Upgrading the Switch Fabric
The switch fabric on the Cisco 12410 Router can be upgraded in the field to a Cisco 12810 Router. This
allows you to upgrade the 10-Gbps switch fabric to a 40-Gbps switch fabric. Table 1 lists Cisco router
model numbers, their corresponding switch fabric speed, and the available upgrade path for each router
model.
