Preparing the installation site
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:

Installing an AC power supply
DANGER
Before beginning the installation, see the precautions in “Power
precautions” on page 11.
Use the following procedures for AC power supplies.
To install an AC power supply, do the following:
1. If you are replacing a defective power supply, remove the power cord, fully
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 8 on page 13). Be sure to support the power supply with
your other hand.
