start functioning properly initially. The router should perform normally until the free resource available
in the eUSB device drops to an unacceptably low level. That low threshold is non-deterministic and hence
the invalid eUSB device should be replaced at the earliest opportunity. System behavior is unpredictable
when the eUSB resources are running low.

Removing and Replacing Cisco ASR 1000 Series Embedded
Service Processors
The following sections describe the procedures for replacing the Cisco ASR 1000 Series embedded service
processors in your system. The module also contains card handles to assist in insertion and removal of the
module and retention of the module into the chassis. The Cisco ASR 1000 Series embedded services processors
have no front panel I/O connectors.
See xref Table 1-2 for information about the embedded services processors that are supported on the
various Cisco ASR 1000 Aggregation Services Routers. On some routers, the embedded services processor
is an integral part of the router. On these routers, you cannot remove the embedded services processor.
For example, Cisco ASR1002-ESP-F is integrated on the chassis of Cisco ASR 1002-F Router.
Note
This section contains the following topics:
Before you begin the procedure, verify that your system meets the minimum requirements as described
in xref Chapter 2,

Important Notes about Cisco ASR1000-ESP Upgrades
You can upgrade from an earlier release of an embedded services processor to a later release. For example,
a router can be upgraded from Cisco ASR1000-ESP10 to Cisco ASR1000-ESP20 or from Cisco
ASR1000-ESP20 to Cisco ASR1000-ESP40.
The following sample procedure describes an upgrade from Cisco ASR1000-ESP20 to Cisco ASR1000-ESP40
on Cisco ASR 1006 Router:
Step 1
Ensure that Cisco ASR 1006 Router has Cisco ASR1000-ESP20 in the F0 slot in the Active state.
Step 2
Insert Cisco ASR1000-ESP40 in the F1 slot. The Cisco ASR1000-ESP40 comes up as the standby.
Step 3
Reload Cisco ASR1000-ESP20. The ASR1000-ESP40 becomes active, the Cisco ASR1000-ESP20 is disabled, and an
error message is displayed.
