Hello rmc[NAME],  Those ports are the default SMI-S / CIM Server ports 5988 - HTTP, 5989 - HTTPS and I would like to assume that CMCNE and Solutions Enabler do not reside on the same host in your environment.  Ideally as long as CMCNE & Solutions Enabler are on separate hosts, there will not be any chances for a port conflict.  In other words, these ports are used for outward connectivity ie ViPR SRM Collectors --> CMCNE / Solutions Enabler  Hope this answers your question.
ViPR SRM 4.0.3 VMAX solution pack uses port 5988/5989 by default when connecting to SE / SMI-S. Brocade solution pack uses port 5988/5989 by default when connecting to CMCNE SMI-S or SMI-S only.  Will that cause a conflict within VIPR SRM 4.0.3?  Or does that matter?  Thank you.
