Figure 3-1 FL SWITCH EP74… view from front
Heat generated by the switch is channeled outwards from the enclosure. For improved con-
vectional airflow, make sure there is at least one rack unit (1U) or 44 mm of space around
all sides of the device or between the devices on the rack.
Forced airflow is not required. However, any increase in airflow will result in a reduction of
ambient temperature and improve the long-term reliability of the equipment mounted in the
rack space.
The color LCD displays switch revision information and port status.
The SecureDigital (SD) port cover covers the following:
– SD card slot #1 (top) is for factory use and is disabled.
– SD card slot #2 (bottom) is available for storing up to 32 GB of Syslog event files.
– The management port, a 10/100 Base-T Ethernet port, that is used as an out-of-band
factory service port. It is disabled by default and not available for user access.
– Power status LEDs indicate the status of the installed power supply modules.
