This equipment can be connected between buildings if any one of the following conditions is true:
●
Cable runs between buildings are less then 140 feet long.

CAUTION
Failure follow these requirements for cable routing conditions may expose the user to electrical shock and expose
the unit to errors or damage.
the unit to errors or damage.
WARNING!
The intra-building ports of the equipment or subassembly are suitable for connection to intrabuilding or unexposed
wiring or cabling only. The intra-building port(s) of the equipment or subassembly MUST NOT be metallically
connected to interfaces that connect to the outside plant (OSP) or its wiring. These interfaces are designed for use
as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require
isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to
connect these interfaces metallically to OSP wiring.

PoE Devices
When connecting power over Ethernet (PoE) devices to a PoE switch, all connections between the PoE
device and the switch must remain inside the same building and use a low-voltage power distribution
system per IEEE 802.3af.
