Replace ECC Card with an ECC Card
PURPOSE
This procedure provides instructions to replace a 12-port ECC card with another 12-port ECC card.
PREREQUISITES
Although these procedures are normally done to replace a failed (inactive) module, always verify
module state before removal.
If an ECC card has a state of OOS-AU or OOS-AUMA, perform the appropriate trouble clearing
procedures before replacing the module. Refer to IXL-101.
It is recommended to disconnect loopback and test connections before proceeding with the
replacement procedure. The TYPE parameter of an ECC card cannot be changed while any of its
ports are in a Loopback state (SST is LPBK) or in a Test state (SST is TACC).
GENERAL
DS3 and ECC working modules can be mixed within the same protection group if the protection
module is an ECC. An ECC/DS3 card protection group is defined when the corresponding protection
slot is provisioned. Refer to table 146-A. The ECC module can operate in an unprotected mode. If the
protection module is a DS3 module, all working modules in the protection group must be DS3. There
is no restriction on the provisioning order.
