Chapter 4 Removing and Installing the NSE
Inserting the Network Services Engine
Inserting the Network Services Engine
The NSE-100 or NSE-150 should be installed in slot 0. For high availability, install a second NSE-100
or NSE-150 in slot 2.
Online insertion and removal (OIR) of the standby NSE is supported. If two NSEs are installed, and one
fails, whether primary or secondary, the failed NSE can be removed without powering off the router, and
a new NSE can be installed.
Caution
Two NSE-100s, two NSE-150s, or two NPE-G100 configurations are supported on the Cisco 7304
router. You cannot use different processors in the same Cisco 7304 router at the same time.
To install an NSE in the router, complete the following steps:
Step 1
Ensure that the router is powered down and the input power cable is disconnected from the router and
the power source. See the
“Powering Down the Router and Disconnecting Input Power” section on
page 4-2
.
Step 2
Attach an ESD-preventive wrist strap between you and an unfinished chassis surface.
Step 3
Remove the new network services engine from its static shielding bag.
Caution
Handle the network services engine by the carrier edges and handle only; never touch the printed circuit
board components or connector pins.

Step 4
Position the locking levers at a 45-degree angle
before
installing the network services engine (see
Figure 4-5
).
Note
If you have difficulty installing a processor in the lowest slot of a Cisco 7304 router that is rack-mounted,
remove the line cards, port adapter carrier cards, and processor from the chassis and reinstall them.
Install a processor in the lowest slot first, then populate the slots above it, in a bottom-to-top order.
Step 5
Align the network services engine in the slot guides (see
Figure 4-5
).
