DANGER
The intra-building port or ports of the equipment or subassembly is suitable for connection to intra-building or unexposed
wiring or cabling only. The intra-building port or ports 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 5) 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.
Installation location
Before installing the device, plan its location and orientation relative to other devices and equipment. Allow at least 3 in. of space at the
front of the device for the twisted-pair, fiber-optic, and power cabling. Also, allow a minimum of 3 in. of space between the sides and the
back of the device and walls or other obstructions.
An Extreme Networks device is suitable for installation in Network Telecommunications facilities and locations where the NEC (National
Electric Code) apply.
The device must be installed in a restricted access location, either a Central Office or customer-premises equipment location.
Redundant power supply installation
The Extreme Networks device ships with one alternating-current (AC) power supply or direct-current (DC) power supply. All models have
two power supply slots, enabling you to install a second power supply for redundancy. If desired, you can install a second supply for
redundancy.
CAUTION
Changes or modifications made to this device that are not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
If you need to install a redundant power supply, it may be easier to install it before mounting the device, although the power supplies are
"hot swappable" and can be installed or removed after the device is mounted and powered on.
This section provides the following procedures:
• Installing a redundant AC power supply - Installing an AC power supply on page 45
• Installing a redundant DC power supply - Installing a DC power supply on page 48
Installing an AC power supply
DANGER
Before beginning the installation, see the precautions in “Power precautions.”
