Installing the Power Cord Retention Lock
The Cisco 819 ISRs have a power cord retention mechanism as an accessory. It locks the power cord to
the router so when a user accidentally pulls out the power cord, the power cord will not come out from
the router. For the complete list of Cisco 819 ISRs that support power cord retention lock, see
Table 1-4 .
This section describes how to install the power cord retention lock.
Step 1
Pre-assemble the o-ring onto the barrel of the power cord as shown in Figure 2-10 .
