CHAPTER 2: Introduction
The Black Cat CAT5 Patch Panels are designed to be
high-performance mainstays of wiring sites for Category 5:
rugged enough for everyday handling in demanding
locations and applications, yet simple and convenient
enough for anyone to work with. Some of their more
important features include:
•A lot of ports in not a lot of surface area. Get 16 or
24 ports on a Panel one rack unit (1U) high, 32 or
48 ports on a Panel 2U high, or 64 or 96 ports on a
Panel 4U high.
•A higher printed-circuit-board capacity than most
other patch panels, which makes the Black Cats
more reliable at Category 5 data rates.
•
Sturdy rolled-edge anodized-aluminum construction.
•Type 110 connectors on the back of the Panel that
don’t protrude—so they don’t snag cables—and
that are specially arranged so that you can punch
cables in a pair-by-pair sequence, preserving pair
twist to within a half-inch (12.7 mm) of the
connectors, as required by EIA/TIA-568.
•Come with a rackmountable Cable Management
Bar, sets of cable ties and Type 110 connector caps,
a sheet of label-paper strips and two adhesive-
backed plastic sheaths.

BLACK CAT CAT5 PATCH PANELS
3.1 The Complete Package
Before you install the Black Cat CAT5 Patch Panel, make
sure you received everything that should come with it:
•The Black Cat CAT5 Patch Panel itself.
•One or more bags containing enough Type 110
connector caps to protect the 110 (rear) side of all
of the Panel’s connectors.
•A bag containing two or four 10/32" screw-and-
washer pairs that can be used to rackmount the Panel.
•Cable ties.
•A Cable Management Bar (CMB) that can be
rackmounted above or below the Panel.
•Two 10/32" screw-and-washer pairs that can be
used to rackmount the CMB.
•A small sheet of perforated strips of heavy paper
that can be used to make cable-identification labels.
•Two adhesive-backed plastic sheaths that can be
stuck to the Panel or the CMB to hold and protect
cable-identification labels.
If you didn’t receive something, or if anything arrived
damaged, call Black Box at [phone] right away.

CHAPTER 3: Installation
3.2 Rackmounting the Patch Panel
To install the Black Cat CAT5 Patch Panel in a rack, hold
the Panel so that at least two of the mounting holes in its
“ears” are positioned over mounting holes in the side
rails of your rack.
If the rack’s mounting holes are not threaded, or are
pre-threaded for screws with a diameter of 10/32", you
can use the screws and washers that we include with the
Panel to mount the Panel on the rack. (The two screws
and two washers we included are sufficient to hold the
Panel on; one screw and washer can go in either
mounting hole on one side of the rack, and the other
screw and washer can go in either hole on the other side
of the rack. If you have two more 10/32" screws and
washers and want to use them in the other two holes, feel
free.)
If the rack is pre-threaded for screws of a different
width, you will have to use your own screws to mount the
Panel.
Place the washers on the screws, push them through
the Panel’s mounting holes, and push or screw them
through the rack’s mounting holes. (If your rack is not
pre-threaded, you will need “cage nuts” or “spring nuts”
of the appropriate width—10/32" for the screws we
provide—to secure these screws from the other side of
the rack. If your rack is pre-threaded, you could use
regular nuts to secure the screws, but they will probably
stay in place without requiring nuts.)

3.3 Rackmounting the Cable Management Bar (Optional)
If you like, you can also rackmount the Cable Management
Bar, an optional companion piece to the Black Cat CAT5
Patch Panel. (The Bar holds hardwired cables in place, in
groups of as many as eight cables.)
Hold the Bar so that the “eyes” of its mounting hooks
are positioned over mounting holes in the side rails of
your rack above or below those you used to mount the
Panel itself.
If the rack’s mounting holes are not threaded, or are
pre-threaded for screws with a diameter of 10/32", you
can use the two screws and washers that we include with
the Bar to mount the Bar on the rack. (If the rack is pre-
threaded for screws of a different width, you will have to
use your own screws to mount the Bar.)
Place the washers on the screws, push them through
the eyes of the Bar’s mounting hooks, and push or screw
them through the rack’s mounting holes. (If your rack is
not pre-threaded, you will need “cage nuts” or “spring
nuts” of the appropriate width—10/32" for the screws we
provide—to secure these screws from the other side of
the rack. If your rack is pre-threaded, you could use
regular nuts to secure the screws, but they will probably
stay in place without requiring nuts.)

CHAPTER 3: Installation
3.4 Wiring the Patch Panel
CAUTION!
The Black Cat CAT5 Patch Panel is intended to be
employed on the protected side of a listed primary
telephone protector. Wiring it in such a way that it is not
protected by a listed primary telephone protector could lead
to the damaging or destruction of the Panel, your site’s
Category 5 wiring, all devices connected to your site’s
Category 5 wiring, all devices electrically connected to
those devices, and your site’s electrical system.
To hardwire (permanently attach) a Category 5 cable to
the Black Cat CAT5 Patch Panel, take these steps:
1. It’s very important that you plan your wiring
scheme ahead of time. Laying out which cables you
want to attach to which ports, and how you want to
group and organize your cables (with the included
cable ties and/or cable guide, or whatever), will save
time and effort and prevent rewiring headaches.
2. If you are using the optional Cable Management
Bar, thread the end of the cable through the
desired hole in the desired cable-group bracket on
the Bar.
3. Remove the outer jacket from the end of the cable.
We do not recommend removing the jacket from
more than the last half-inch or so of the cable. Do
not strip the insulation from any of the individual
wires. The wires in the cable must not be thicker
than 22 AWG or thinner than 26 AWG.

4. Face the Type 110 (rear) side of the Panel and find
the connector you want to use. The connectors are
arranged in groups of eight: Viewed from the rear,
the connectors with the lowest RJ-45 (front) side
numbers (1 through 8) will be on the far right; the
next group (9 through 16) will be the second from
the right; and so on. The eight connectors in each
group are indiviually numbered on the Type 110
side from 1 to 8, starting with “1” in the upper
right-hand corner and zigzagging up and down to
“8” in the lower left-hand corner. So, for example,
on a 32-port Panel, the Type 110 connector for port
19 will be in the third group of eight from the right,
and will be the second connector from the right in
the upper row (the connector labeled “3”). See
Figure 3-1 below.

of an EIA/TIA-568A model of the Panel.

CHAPTER 4: Operation
NOTE
When you attach the wires in your Category 5 cables to the
Black Cat CAT5 Patch Panel, be careful not to let the pairs
untwist more than a half-inch (13 mm). Because NEXT and
other electrical performance features are affected by twist,
in EIA/TIA-568 the EIA and TIA specify “preserving wire twist
as closely as possible to the point of mechanical
termination.” In addition, TSB-40 declares that “the amount
of untwisting in a pair as a result of termination to connector
hardware shall be no greater than 13 mm (0.5 inches) for
Category 5 and shall be no greater than 25 mm (1.0 inch)
for Category 4 cable.”
5. Place the ends of the eight individual wires in the
cable across the contact gaps in the Panel’s Type
110 connector, with the ends of the wires toward
the outside (toward the edge of the Panel). The white-
with-colored-stripe (white/colored) wire must be
placed to the left of the correspondingly colored
prong and the colored-with-white-stripe (colored/
white) wire to the right of the prong. For example,
place the white/brown wire to the left of the brown
prong and the brown/white wire to the right of the
brown prong.
6. Position an Type 110 punchdown tool over one of
the wires, with the tool surface labeled “CUT”
toward the outside (toward the edge of the Panel), as
shown in Figure 3-2 on the next page.

Figure 3-2. Using a punchdown tool to hardwire the Panel.
7. Push the tool and punch the wire down. The tool
will force the wire into the contact gap and lop off
the wire’s protruding end.
8.
Repeat steps 6 and 7 for each of the seven other wires.
That’s all there is to it. Repeat this process for all of the
cables you would like to hardwire to the Black Cat CAT5
Patch Panel.
Once you have finished hardwiring cables, put a
connector cap on each of the Panel’s Type 110 connectors
that you have left empty. Now you can attach and
remove patch cables terminated with RJ-45 plugs to and
from the active sockets on the front of the Panel at will.

CHAPTER 3: Installation
3.5 Organizing the Cables (Optional)
If you haven’t installed the Cable Management Bar but
would still like to group the cables, or at least keep them
together for running elsewhere, you can tie bundles of
them together with the included cable ties.
Whether you’ve installed the Bar or not, you can use
the included sheet of label strips and plastic sheaths to
identify which port or cable is which. First, remove the
covering from the adhesive backing on one or both of the
plastic sheaths, then mount the sheath(s) on the Panel
and/or the Bar. Then tear off a strip of the label paper
and fold it in half along the crease; cut it into small
sections if you want to label ports, cables, or cable groups
with individual squares of paper. Write, stamp, color-
code, etc., the label paper as you like and slide it into one
of the sheaths to the desired position. (If you would like
to make more labels than there is paper for, or if you
need to replace the labels later, you can make more labels
from any thick or well-folded paper.)
A more elegant way to identify ports is by using Color
Icons of various colors (FT940 through FT948). The
Icons are designed to snap right into the Panels directly
above their RJ-45 ports. Call Black Box if you would like
some of these.
