Switch Features

26 Edge Switch 2/24 Installation Guide

Three cooling fans integrated in each power supply assembly (six fans total)

provide cooling for the power supplies and CTP card, as well as redundancy for

continued operation if a single fan fails. Fans are removed and replaced as part of

the integrated power supply.

Power supply requirements are listed in “Technical Specifications” on page 133.

Maintenance Port

The rear panel provides a 9-pin DSUB maintenance port, as shown in Figure 3 on

page 25, that provides a connection for a local terminal or dial in connection for a

remote terminal. Although the port is typically used by authorized maintenance

personnel, operations personnel can use the port to configure switch network

addresses.
