User's Manual

•
The power input is provided on the extreme right through an IP-65 compliant gland for DC. An ordinary
DC cable can be routed through the gland. For AC inputs, a special IP-65 compliant connector system
should be used. The AC input cable can be removed from the system without opening the door.
•
Each SFP port is connected with an LC-LC patch cable from the SFP module to the bottom panel. For
the external connectivity, an LC cable system with IP-65 sealing should be used.
•
For configurations with two or three SFP ports, one or two copper ports will have an internal patch cable
arrangement. For these configurations, an external RJ-45 connection with IP-65 sealing should be used.
•
For configurations with four SFP ports, the RJ-45 connections for the copper ports with common copper
cables (non IP-65 compliant) should be used. These cables can be routed through the four-wire gland
shown adjacent to the power entry cable.
•
The alarm port has a single Cat5e cable routed through the four-wire gland.
•
The management, Ethernet, and console ports are usually not used in the OSP because the access to the
router is limited (the Wi-Fi interface is used instead). However, when these ports are used, the
corresponding cables should be routed through the four-wire gland.
In certain configurations, like 4 SFPs, 2 CUs, and alarm, it is not possible to route the
console and management ports through the four-wire gland.
Note
•
For the optical ports, multimode patch cables are supplied by default with the router. The single mode
cables can be ordered separately.
