Smart Install Support
The Cisco SM-X Layer 2/3 ESM supports the Smart Install feature. The Smart Install is a plug-and-play
configuration and image-management feature that provides zero-touch deployment for new switches. You
can ship a switch to a location, place it in the network and power it on with no configuration required on the
device.
A network using Smart Install includes a group of networking devices, known as clients, that are served by a
common Layer 3 switch or router that acts as a director. In a Smart Install network, you can use the
Zero-Touch Installation process to install new access layer switches into the network without any assistance
from the network administrator. The

Using OIR to Manage the Cisco SM-X Layer 2/3 ESM
The online insertion and removal (OIR) feature allows you to insert or remove your Cisco SM-X Layer
2/3 ESM from a router. The Cisco SM-X Layer 2/3 ESM must be gracefully powered down before
removing it from the router using the managed OIR or soft OIR feature. The managed OIR feature allows
you to stop the power supply to your module using the hw-module sm command and remove a module
from one of the subslots while other active modules remain installed on the router.

Note
If you are not planning to immediately replace a module after performing OIR, ensure that you install a
blank filter plate in the subslot.

The oir-stop option allows you to gracefully deactivate a module and the module is rebooted when the-
oir-start option of the command is executed. The reload option will stop or deactivate a specified
module and restart it. See the

Note
The managed OIR feature is only supported on Cisco 3900 Series ISR.
Managing Backplane Switch Ports
When there are no legacy switch modules such as the HWIC-4ESW module in the router, a 2nd GE
interface gigabitethernet slot/1 is created for the SM. This is a Layer-2 switch interface and used to
manage the inter module connectivity with other SM in the system via the backplane MGF. You can use
the switchport CLIs to manage the L2 switch properties (e.g. access mode, trunk mode, native vlan etc.)
for this interface. See the,
