Enabling and Disabling Enhanced Port Performance (EPP)

EPP can assist in connecting with SFF-8431 non-compliant or electrically deficient devices. EPP can be
used on some links to enhance the receive signal sampling resolution management and help to improve the
link integrity to the link partner. The following steps should be followed to determine if EPP should be
enabled:
1
Check the current link quality - Check the current link quality of the interface.
2
Diagnose any link quality issues - If the Link Quality is not 'Good'. Perform a few basic
troubleshooting steps to determine if the issue is with the link partner and whether enabling EPP can help
improve the quality.
3
Enable EPP - If it's determined that the issue is with the link parter, enable EPP.
EPP - Product and Transceiver Support
Only certain transceivers support enabling EPP. Additionally, depending on the revision of the
OmniSwitch, there are port restrictions due to the power requirements of enabling EPP as shown in the
table below.
