Removing and Replacing FRUs from the Cisco ASR 1000 Series Routers
Note
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.
This section contains the following topics:
Note
Before you begin the procedure, verify that your system meets the minimum requirements as described in
xref Chapter 2, "Cisco ASR 1000 Series Routers Component Overview."
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.
If there are two different versions of the Cisco ASR1000-ESP in a router when you reload, the F0 slot always
Note
comes up as Active and the F1 slot comes up as Standby or Disabled, depending on whether the F1 slot has a
later version of the Cisco ASR1000-ESP or an earlier one. A downgrade from a later version ESP to an earlier
version is not supported and that is the reason the Cisco ASR1000-ESP20 is disabled in this step. To downgrade
back to a Cisco ASR1000-ESP20, you must remove the Cisco ASR1000-ESP40 and reload the router. Similarly,
to downgrade back to a Cisco ASR1000-ESP10 from a Cisco ASR1000-ESP20, you must remove the Cisco
ASR1000-ESP20 and reload the router.
Removing a Cisco ASR1000-ESP
To remove the Cisco ASR1000-ESP5, Cisco ASR1000-ESP10, Cisco ASR1000-ESP20, or Cisco
ASR1000-ESP40 from the Cisco ASR 1000 Series Routers, follow this procedure:
SUMMARY STEPS
1. Slip on the ESD-preventive wrist strap that was included in the accessory kit. Loosen the captive screws
on the Cisco ASR 1000 Series Embedded Services Processor.
2. Using the handles on both sides of the module, with two hands gently slide the Cisco ASR 1000 Series
Embedded Services Processor (ESP5, ESP10, ESP20, ESP40) out of the chassis slot.
