1-Port DOCSIS Mini-Physical Interface Module LEDs
The Data over Cable System Interface Specifications Mini-Physical Interface Module (1-Port DOCSIS Mini-PIM) has five LEDs. Figure 1 describes the LEDs available on the 1-Port DOCSIS Mini-PIM.
Table 1 describes the LED states.
Table 1: 1-Port DOCSIS Mini-PIM LED States
LED | Color | State | Description |
|---|---|---|---|
PWR | Green | On | The 1-Port DOCSIS Mini-PIM has been powered on and completed the power-on-self-test (POST). |
Red | On | The 1-Port DOCSIS Mini-PIM has failed the POST. | |
DT (Downstream) | Green | Blinking | The 1-Port DOCSIS Mini-PIM scans for a valid downstream DOCSIS channel to lock onto a downstream channel. |
On | The 1-Port DOCSIS Mini-PIM has locked onto the DOCSIS downstream channel. | ||
UT (Upstream) | Green | Blinking | The 1-Port DOCSIS Mini-PIM scans for a valid upstream DOCSIS channel to lock onto an upstream channel. |
On | The 1-Port DOCSIS Mini-PIM has locked onto the DOCSIS upstream channel. | ||
LINK (to CMTS) | Green | Blinking | The 1-Port DOCSIS Mini-PIM has an active link with the CPE device, but data communication is not taking place. |
On | The 1-Port DOCSIS Mini-PIM has an active link with the CPE device, and data communication is taking place. Note: The Link LED does not blink for data traffic that originates or terminates at the cable modem. | ||
ONLINE | Green | Blinking | The 1-Port DOCSIS Mini-PIM is establishing a connection to the SRX Series device. |
On | The 1-Port DOCSIS Mini-PIM is synchronized with the SRX Series device. |
