Step 4
Place your thumbs on the ejector levers (see figure
Cisco ASR 914 Router RSP Installation
) and simultaneously
rotate the ejector levers outward to unseat the module from the backplane connector.
Step 5
Grasp the front edge of the module and slide the module straight out of the slot. Place your hand under the
module to support its weight as you slide it out from the slot. Do not touch the module circuitry.
To prevent ESD damage, handle modules by the carrier edges only.
Caution
Step 6
Place the module on an antistatic mat or antistatic foam, or immediately reinstall the module in another slot.
Step 7
Install blank module filler plates (Cisco part number A9XX-RSPB-BLANK) in empty slots, if any.
Hot-Swapping an RSP Module
The hot-swap allows you to remove and replace a redundant RSP module without powering down the router.
This feature, called hot-swapping or OIR, allows you to remove and replace a redundant module without
disrupting router operation.
When two redundant modules are installed in the router, only one of the modules is active. The other one runs
in standby mode, ready to take over processing if the active module fails.
When you remove or insert a redundant module while the router is powered on and running, the router does
the following:
1.
Determines if there is sufficient power for the module.
2.
Scans the backplane for configuration changes.
3.
Initializes the newly inserted module. In addition, the system notes any removed modules and places those
modules in the administratively shutdown state.
4.
Places any previously configured interfaces on the module back to the state they were in when they were
removed. Any newly inserted interfaces are put in the administratively shutdown state as if they were
present (but unconfigured) at boot time. If you insert the same type of module into a slot, its ports are
configured and brought up online to the port count of the original module.
The router runs diagnostic tests on any new interfaces and the test results indicate the following:
• If the tests pass, the router is operating normally.
• If the new module is faulty, the router resumes normal operation but leaves the new interfaces disabled.
• If the diagnostic tests fail, the router stops operating, which usually indicates that the new module has a
problem in the bus and should be removed.
Use the following guidelines when performing an OIR on an IM:
• Allow at least 2 minutes for the system to reinitialize before inserting a new IM.
• Avoid inserting a new IM during bootup until the active and standby RSPs have reached an OK state.
• When inserting multiple IMs into the chassis, wait until each IM reaches an OK state before inserting
the next IM.
