SECTION 1.0: INTRODUCTION
1.1 HS DEFINED
The CM9760-HS (Hot Switch) provides single-node, switching control between two CM9700-CC1
matrix switches. The default HS package consists of three subunits*, interconnected via in out, DB37,
male-to-male, molded cables that form a common bus for the subunits. These units provide the
interfaced system with operational redundancy.
Failure of the controlling matrix switch (designated the Master) passes control to the backup (designated
the Slave). Conversely, if the Slave unit fails, control remains with the Master unit. Any system failure
generates a system error that lights the FAULT LED (visual), and turns on an accompanying audible tone.
The audible signal is automatic unless turned off by DIP switch 1-1 (see Figure 2-4, DIP Switch
Configuration)
and the external devices connected to the CPS and SEU output ports.
Appendix 4.4, HS
, for more information.
Users upgrading from previous hot switch models should consult
, where important differences
.
Figure 1-1 depicts the basic physical relationship between the HS, the interfaced CC1s,
* The Serial Expansion Unit (SEU) is one of these units. However, it varies in number from one
(default), up to a possible eight units, depending on system configuration. Additional SEU units are
physically added to the hot switch via the HS common bus. Two SEU units are needed to interface a
fully populated CC1 (four Sercom cards containing a total of 32 ports). Future development may
require more than 32 Sercom ports to be interfaced. When that happens, SEU units (up to eight
total) can be added to the common bus to accommodate the increase in Sercom port population.

Diagnostic equipment connected to CPS output ports display the status of HS health. Other devices,
connected to SEU output ports are under CC1 A or CC1 B control. For this reason, the interfaced
matrix switches must be hardware-software clones of each other in order for either to control the
same set of devices and to ensure a smooth transfer if a control transition (changeover) occurs.
Matrix switch equality is assured in the following manner:
• Both switches must physically interface the HS in the same way. All cables and connections on
the A-side, switch-to-HS interface, are duplicated on the B-side. Basic interface requirements are
discussed in installation subsection
setup, are discussed in
Section 4.0 Appendices.

• The physical equivalence of the matrix switches is likewise mirrored in their respective software
configuration file sets (Comms, Monitor, Camera, etc.) that are used to initialize and operate
each switch. Both sets must be identical.

The rear view of a matrix switch (referenced in the block diagram of Figure 1-1) is shown in
Figure 1-2. Outputs destined for HS connections can be categorized, corresponding to the designated
functions of the subunits to which they are attached on the hot switch. For discussion purposes, these
outputs are partitioned into three groups: the Control group, the Diagnostic-Peripheral group and the
External Expansion group.

1.3 HS HARDWARE THUMBNAIL
Figure 1-3 expands the HS portion of Figure 1-1 to illustrate an uncluttered, thumbnail rear view of the
hot switch subunits that comprise a default HS configuration. Connection cable destinations from each
CC1 (matrix switch), referenced in the previous figure, are attached to the appropriate side (CC1 ‘A’ or
CC1 ‘B’) of the hot switch subunits. The subunit acronyms have the following meanings: the CCC
(Computer Changeover Control), the CPS (Computer Peripheral Switch) and the SEU (Serial
Expansion Unit).
Note that the CCC front panel is included in this illustration. Operation buttons for the user are located
there. Also shown is the 37-pin, D-type, molded cable, used to create common bus connectivity
between the subunits. (Except for the CPS, one DB37 cable is supplied with each subunit). Front
panels for the CPS and SEU are similar to that shown for the CCC (minus the operation buttons), with
labeling appropriate to each unit.

THE CCC (Computer Changeover Control)
The CCC subunit is the heart of the hot switch. Data connections between the interfaced CC1s
(matrix switches) and the HS are located here. Two connector types that correspond to two
communication types for the data line to the CCC are provided: RJ-45 or DB9. You can use either, but
the connector type chosen determines the communication protocol you must use and vice versa.
Both are illustrated in Figure 1-5. In the top portion of Figure 1-5, the RJ-45 data line connection (one
from each switch) is shown. If RS-422 communication is chosen, the data cable from a port on matrix
switch CC1 ‘A’ (an RJ-45 Sercom port, usually port 5) is run to the RJ-45 CC1 A port on the CCC. A
similar cable is run from CC1 ‘B’ to the RJ-45 CC1 B port on the same CCC. These cables are reversed or “flipped” and utilize pins 1, 2, 7, and 8 as depicted in Figure 1-4. Alternately, in the bottom
portion of Figure 1-11, the RS-232 data line connection is shown. A DB9 cable is run from either the
COM 1 or COM 2 port (on the respective CC1 ‘A’ or CC1 ‘B’ switch) to the appropriate (CC1 A or B)
DB9 port on the CCC. The cables for the DB9 data connection runs are not supplied. Pelco
recommends that RS-422 communication be used whenever possible. The cables for the RS-422
data connections are provided.

In addition to communications, there are number of additional functions handled by the CM9760-CCC.
POWER The power-input connector, fuse, and ON/OFF switch are located here. Input
power for the entire HS originates here. Power is distributed to the CPS and SEU
subunits via DB37 common bus connections.
LOGGING
PRINTER PORT This is used, if desired, as an output logging device for system or status reports
related to hot switch operation only. The port supports dot matrix printers capable
of IBM or Epson emulation modes, such as the Okidata 320 (non-turbo) and the
Okidata 390 (turbo) or 391 (turbo).
LEDs The FAULT, A, and B LEDs are located on the front panel of the unit. These give
visual indications of system status with respect to control, mode of operation, and
system failure. See the
LEDs
section of
3.3 Operator Tools.
FRONT PANEL
BUTTONS The front panel buttons are utilized by the operator for responding to system
errors, for checking system status, and for operational control when changes are
made to system hardware and/or software. See the
of
3.3 Operator Tools

Each duplicate section is labeled. From left to right, they are the CC1 ‘A’ section, the CC1 ‘B’ section,
and the EQUIPMENT section. The first two (CC1 ‘A’ and CC1 ‘B’) are connection input destinations
for the corresponding switch it interfaces—one from the A-side, and one from the B-side switch. The
third section (EQUIPMENT) provides the connectors to which the following standard diagnostic
devices can be attached:
1. An AT keyboard (to the AT KBD connector)
2. A VGA monitor (to the VGA connector)
3. A system printer (to the PRINTER connector)
4. A PC W/Pelco MGR software (to the COM 1 port)
As a user, you are always connected (through either one matrix switch or the other) to the diagnostic
tools that are attached to the EQUIPMENT output ports. The switch through which you operate (the
one in control and designated the Master) is normally granted automatic access to those devices
(default). If control is switched, the backup switch (Slave) becomes the designated Master, roles are
reversed, and the output diagnostic connections change to follow suit. This happens automatically if
DIP switch 1-2 is ON and DIP 1-6 is OFF (default). See Figure 2-4, DIP Switch Configuration.
Note that only four diagnostic devices are listed for the five available output ports. Two of the five
output ports deserve further comment.
COM 1 is reserved for the connection of the PC with MGR software (see Figure 1-11).
COM 2 can be used in two ways:
1. As a “user” defined configuration for the connection of devices and/or electronic equipment to
the COM 2 A and B inputs and to the COM 2 EQUIPMENT output port. The COM 2 ports are
D-type, 25-pin connectors, and can be used for the connection of user-optioned equipment.
Applied voltages to COM 2 connector pins should not exceed 25 VDC. For this use, the
operation of the COM 2 port is not necessary for the successful operation of any function of the
HS. Insert A of Figure 1-6 is a diagrammatic drawing of the wiring of the COM 2 connectors.
2. For the connection (to the EQUIPMENT section’s COM 2 output port) of an RS-232, DT (Data
Translator). As part of the CPS package, three DB25 (female) to DB9 (male) adapters are provided for this purpose (along with the associated cabling for the A- and B-side inputs to these
adapters).
10 C578M-A (4/05)
This allows users with existing RS-232 DT devices to retain that configuration capability in the new
HS. Figure 1-6 highlights the geometry of this hookup.
Additional DTs of the same type must be connected to CC1 Sercom ports (via SEU output ports of the
HS) and require RS-232 to -422 converters.
20078
Figure 1-6. COM 2 Port Options
A couple of working rules with respect to diagnostic tool availability are in order here. During default
operation (see Figures 2-4 and Figure 2-5) diagnostic tools attached to EQUIPMENT output ports
“follow” the switch in control. Under these conditions, the following results can be expected when the
described operation is performed:
1. You can view, at will, the diagnostic activity for either switch (Master or Slave) regardless of the
operational mode (including default) as long as that switch is online. This is done by pressing the
KVD (Keyboard, Video, Data) A (or B) button located on the front panel of the CM9760-CCC for
the A- or B-side diagnostic view you want to see (see Table B, Front Panel Button Operation).
When the KVD button is pressed, you will view the devices connected to the AT KBD, and VGA
port connections for the side (A or B), (Master or Slave) that you selected. It is important to note
that the PRINTER, COM 1, and COM 2 ports do not follow KVD activity under any circumstances.
2. If the diagnostic view is switched manually via the KVD button, as in (1), it remains there until
(a) the operator manually switches back to the opposite side, or until
(b) the system forces a change due to a system fault. A system fault may or may not result in a
return to the original diagnostic view. That depends on which switch becomes the designated Master when the changeover, if deemed necessary, occurs. This is determined by
the HS itself. It occurs automatically as the result of configuration settings and is not under
user control.
3. Any system change (as noted in 2b) co-opts any existing diagnostic view and any resulting
change occurs under the control of the HS and not the operator. Moreover, the HS controls and
automatically transfers ALL ports (including COM 1 and COM 2) to the control of the designated
Master in the event of a system failure.

The SEU subunit of the HS, like that of the CPS, is also divided into three sections. Devices
connected to the SEU EQUIPMENT output ports are under the control of only one CC1 at a time. The
controlling switch is designated the Master, regardless of mode (synchronous or asynchronous).
Unlike the CPS, however, there are no predefined port designations for SEU Sercom input ports that
physically correspond to the port designations as they are defined by physical location on any
9760-CC1 matrix switch. On the matrix switch, port 5 is port 5 and is always located at the “port 5”
position, and so on.
The physical relationship between matrix switch Sercom outputs and the A/B inputs on the SEU are
defined by the following statements:
1. The function of each Sercom input port on the SEU (CC1 ‘A’ or CC1 ‘B’) is characterized by
whatever is plugged into it.
2. A specific physical relationship (depicted in Figure 1-7) exists internally between SEU Sercom
inputs (A or B) and associated SEU EQUIPMENT outputs.
The Sercom ports on the SEU shown in Figure 1-7 are isolated and numbered (for explanatory purposes);
the ports on the SEU are physically related as illustrated.

Figure 1-7. SEU Port Relationships
The depiction above shows CC1 ‘A’ input A1, connected to the output device attached to E1.
The physical relationship depicted above is repeated for all corresponding physical port locations;
that is, A2 is related to B2 and the output E2 in the same way that A1 is related to B1, and the E1
output.
This relationship holds true for the remaining port locations: A3-A16, B3-B16, and E3-E16.
In line with the port relationship just discussed, you must also maintain corresponding equipment
integrity with respect to the input port locations chosen for attaching A- and B-side input cables. This
is so that output control, from either matrix switch, of a device connected to a specific SEU output
port, corresponds, in fact, to the same physical device.
For example: If a matrix bay is hardware-software configured for attachment to port 7 on 9700-CC1 A,
then it also must be configured the same for port 7 on 9700-CC1 B, since the CC1s must be hardwaresoftware clones of each other. If you then run a cable from 9700-CC1 A, port 7, to the CC1 ‘A’ side of the
SEU and attach it to the A1 port, then you must also run a corresponding cable from 9700-CC1 B, port 7,
to the CC1 ‘B’ side of the SEU and attach it to port B1. The matrix bay itself, is connected to the corresponding output port, E1, on the SEU.
As indicated above, the configured outputs of 9700-CC1 ports can be plugged into any input port on
the appropriate SEU, as long as you allow for the physical constraint illustrated in Figure 1-7, above.

A NOTE OF CAUTION: Random attachment of cabling between CC1s and SEUs can lead to confu-

sion about what is attached where. It is suggested that you map the physical port arrangement found in
your CC1 outputs to those utilized on the SEU (as far as that is possible). One method is to mentally
rotate the SEU (clockwise or counterclockwise, it does not matter) and associate the port locations you
use on the SEU to those existing on the CC1. In Figure 1-8 , the CC1 ‘A’ side of the SEU is shown
rotated counterclockwise. You can extend the use of this visual mnemonic to the SEU’s B side, the
output, and additional SEUs, if needed (also see the NOTE in Figure 1-8).

MASTER/SLAVE STATUS FOR CC1
Sercom port 1 on the CC1-A or CC1-B side of the SEU subunit may be wired to provide the current
status of the CM9760-HS. This wiring connection will allow for monitoring that alerts the user to
primary (master) CPU (CC1) failure. When the secondary (slave) CPU assumes primary control, the
user can be alerted remotely via the closure of an external alarm. This connection is made by
constructing an RJ-45 terminated wire (not provided) and shorting pins 1 and 2 (CC1-A) or pins 7 and
8 (CC1-B) together on the CC1 side
side port 1. See Figures 1-9 and 1-10.

1.5 INSTALLATION PREVIEW
Figure 1-11 combines elements of previous illustrations into what is essentially a wire routing of the
block diagram of Figure 1-1. This is an overview of the physical geometry of an HS integrated into a
basic, default system configuration.
1-11 into its logical component groupings, where cabling requirements for each section are isolated
and examined in detail. Cabling in the current model hot switch is rather straightforward.
Other Remarks:
In addition to basic hookup, which covers the information needed for a new, single-node installation,
the following configuration processes are discussed in
• HS addition to an existing configuration, (no hot switch currently installed)
• HS update, (previous model of hot switch installed)
• HS update (current model hot switch installed)
• HS and networked configurations
Installation Checklist:
The basic install process for integrating a hot switch within a single system node can be broken down
into the following steps:
1. Mount the components of the hot switch (standard rack-mount) in such a way as to take
advantage of the equipment that will attach to each unit. At the same time, be mindful of the relatively short interconnect cables that form the common bus between the subunits of the HS.
Install the interconnect cables that form the common bus (see Figure 1-3 for a picture of this
cabling). Install the power cord on the CM9760-CCC, but do not apply power to the unit.
2. Connect all remaining cabling that is required for your system node. Follow, in order, all items of
2.1 Physical in Section 2.0 Installation
and two located behind the front panel of the CM9760-CCC subunit (see Figure 2-4).

, breaks up Figure
3. Install all required software. Ensure that duplicate sets of configuration files for the
interfaced matrix switches are installed on the respective hard drives of each switch.
Check to make sure that port references to attached equipment match the equipment
actually attached to those ports. Refer to the appropriate sections of the latest version of
the MGR programming for general information on filling out configuration files. Refer to
the appropriate sections of the latest revision of the matrix switch manual (C541M), for
information on installing configuration files and other items related to file manipulation.
Be sure to add the hot switch to the COMMS configuration file, if not already done.
4. After all cabling and software is installed, apply power to the HS and all attached equipment and
let the systems initialize (see
2.2 Power-up and Initialization
in
Section 2.0 Installation
).
