Exchanging an Adapter
Note: The adapter you replace must be of the same type as the original. Otherwise, you will need to
reconfigure. See the
2216 Introduction and Planning Guide and the Multiprotocol Access Services
Software User’s Guide .
1
Locate the adapter module to be replaced.
Attention:
a. Adapters are hot pluggable, but you must disable all adapter ports before you remove cables.
See “Suspend Traffic on an Adapter Port” on page F-7.
b. If an adapter is removed prior to disabling the ports, a machine check can occur and the 2216
may become idle.
c. If you are removing a serial adapter (EIA 232E/V.24, V.35/V.36, X.21, which are LICs 282, 290
and 291), you need to disable the WAN Reroute process before you remove the adapter. (See
“Disabling Interfaces that Have WAN Reroute Enabled” on page F-8.)
2
Label the cables for correct reconnection.
3
Loosen the screws (if present) that secure the cable or cables.
4
Remove the cable or cables.
Attention: You must turn the adapter’s thumbscrews simultaneously when unseating or seating the
adapter during removal or installation. By doing so, you prevent stripping the thumbscrews. If you
strip the thumbscrews, you may not be able to seat or reseat the adapter correctly.
5
Loosen the screws on the adapter.
