PTP 820S, PTP 820C, and PTP 820C HP
Links with copper Ethernet cable drops are powered via Power over Ethernet (PoE) equipment (PoE injectors).
Links with fiber Ethernet cable drops are powered via external DC equipment.
(These configurations were chosen because they are the most likely to be implemented. Links with copper Ethernet drops using external DC require additional surge suppression—why not take advantage of the built-in surge suppression and use PoE? Links with fiber Ethernet drops using PoE for power only require PoE injectors—why not just use external DC?)
When does LINKPlanner use copper Ethernet versus fiber Ethernet cable drops?
Unprotected link types (1+0, 2+0, and 4+0) populate the BOM with PoE and copper Ethernet.
For configurations that support antenna heights greater than 90 meters (295 feet), unprotected link types populate the BOM with external DC and fiber.
When does LINKPlanner assume out-of-band management versus in-band management?
Protected link types (1+1 and 2+2) populate the BOM for out of band management. All other link types populate the BOM for in-band management.
If a link requires out of band management, add appropriate out of band management Ethernet cabling and ALPU surge suppressors for antenna heights 90 meters or less.
PTP 820C and PTP 820C HP
Ethernet Configuration pull-down menu options are as follows:
- "Single Ethernet (MC-ABC)" means one single Ethernet cable per radio, with one MC-ABC key per Tx.
- "Multiple Ethernet (with LAG)" means two Ethernet cables per radio, with internal PTP 820 LAG.
- "Multiple Ethernet (without LAG)" means two Ethernet cables per radio, with link aggregation in the connected external switches.
When installing Multiple Ethernet options, exercise caution to avoid Ethernet loops by configuring the PTP 820 and/or external switches appropriately.
PTP 820C
Copper Ethernet cable runs for ETH2 and/or MGT require ALPU surge suppressors, top and bottom of the tower. (Quantity x2 per copper Ethernet cable run.)
Ethernet Configuration Multiple Ethernet (with or without LAG) for 2+0 and 4+0 is not supported for antenna heights greater than 90 meters.
PTP 820C HP
Default radios are non-MIMO (MIMO radios are in New Extra)
Copper Ethernet cable runs for ETH1, ETH2 and/or MGT require ALPU surge suppressors, top and bottom of the tower. (Quantity x2 per copper Ethernet cable run.)
PTP 820G
Ethernet Configuration pull-down menu options are as follows:
- "Single Ethernet (MC-ABC)" means one single Ethernet cable per modem, with one MC-ABC key per Tx.
- "Multiple Ethernet (with LAG)" means two Ethernet cables per modem, with internal PTP 820 LAG.
- "Multiple Ethernet (without LAG)" means two Ethernet cables per modem, with link aggregation in the connected external switches.
When installing Multiple Ethernet options, exercise caution to avoid Ethernet loops by configuring the PTP 820 and/or external switches appropriately
