The lower five ports are in pass-through (non-protect) mode. Indicates that the lower five ports are in protect mode. Alarm condition. Note Only the upper LED is used for downstream switch cards. Each upstream switch card has two LEDs and each downstream switch card has one LED to indicate the working status of the port. The upstream switch module operates over the frequency range of 5 MHz to 85 MHz. The downstream (high-frequency) switch module operates over the frequency range of 54 MHz to 1002 MHz. During normal system operation, upstream switches all direct traffic to their respective default termination interfaces. The switch card should provide a minimum of 65 db of isolation from connector port to connector port during normal operation and more than 65 db when operating in protect mode. When an upstream or downstream switch module initially boots, the LEDs briefly cycle on in sequence.
