Replacing an E4SA CRU

11 If you determined that a SWAN concentrator is connected to the E4SA
CRU to be replaced, determine the names of the WAN subsystem IOPs
configured to use that SWAN concentrator.
Use the SCF INFO DEVICE command:
INFO DEVICE $ZZWAN.#*
Scan the output of the command for the SWAN concentrators you
identified in Step 10. Make a note of the WAN subsystem IOPs that use
the SWAN concentrators connected to the E4SA CRU.
The example shows the output of this command.
12 Identify the SNAX/Ethernet lines configured on the system.
LISTDEV TYPE 58,6
The example shows the output of this command.
13 Determine if any of the SNAX/Ethernet lines configured on the system
use the LIFs on the E4SA CRU to be replaced.
Use the SCF INFO LINE command with the SUB PU and
ASSOCIATESUBDEV options for each SNAX line you identified in Step
12:
INFO LINE $<line-name>, SUB PU,
ASSOCIATESUBDEV
Scan the output of the command for the names of the LIFs you identified
in Step 1. Make a note of the SNAX lines that use the LIFs.
The example shows the output of this command.
