M40 Router Routing Engine Serial Number ID Label Location
For M40 routers, the serial number that you use depends on whether you purchased the Routing Engine housing or just the Routing Engine. If you purchased the Routing Engine housing, the serial number is located on the maxicab, as shown in Figure 54. If you purchased the Routing Engine only, remove the Routing Engine and locate the serial number ID label, as shown in Figure 54. If there are multiple labels on the Routing Engine, the label marked "Teknor Silicon Serial ID" is the correct serial number.
