Grounding

Maintain reliable grounding of a rack-mounted ETEP. Pay particular attention to supply connections other than direct connections to the branch circuit, such as the use of power strips.

Maintenance

Allow at least 19 inches (48.3 cm) of clearance at the front of the rack for maintenance. Use a cable- management system to help keep cables organized, out of the way, and free from kinks or bends that degrade cable performance.

Firewall Ports

Table 13 lists the protocols that are used by the ETEPs and the EncrypTight Manager system. Make sure that any firewalls in your system are configured to allow for the protocols that are required for your deployment: standalone ETEPs used for point-to-point encryption or ETEPs used in the EncrypTight Manager system.
