Cabling infrastructure
Ensure that the proper cabling is installed in the site.
Attention: The intra-building port(s) of the equipment or subassembly is suitable
for connection to intra-building 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 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.
Installation location
Before installing the device, plan its location and orientation relative to other
devices and equipment. Allow at least 3 inches of space at the front of the device
for the twisted-pair, fiber-optic, and power cabling. Also, allow a minimum of 3
inches of space between the sides and the back of the device and walls or other
obstructions.
The device is suitable for installation in Network Telecommunications facilities and
locations where the NEC (National Electric Code) apply.
Installing a redundant power supply
The switch base configuration includes one alternating-current (AC) power supply.
All models have two power supply slots, enabling you to install a second power
supply for redundancy.
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:

Before beginning the installation, see the precautions in "Power precautions"
on page 13.
loosen the power supply locking screws, and remove the defective power
supply by pulling it out of the power supply bay, using the power cord
retaining clip as a handle (see Figure 9 on page 15). Be sure to support the
power supply with your other hand.
