9. When commands are sent from the host computer, alarms, etc., the intended action may be verified by
selecting the appropriate monitor with the keypad and checking to see if the correct camera is indicated in the
keypad display area.
Installation Considerations:
1. Prior to disconnecting any of the operational system, a survey of the system should be completed. This survey
should indicate the addresses of all system keypads and whether they are operational or not. The same should
be completed for all PTZ cameras. Determining if all system components are operational prior to replacing the
CPU will eliminate needless troubleshooting after cutover to the V1500CPU.
Note: If the PTZ control portion of the system utilizes half duplex control it will be necessary to check the
response functionality of the system. A half duplex configuration can typically be distinguished by one of the
following:
• Keypad selection of A/P or A/I results in an indication on the keypad; this is noticeable either on a built-
in button “LED illumination” or a display on the LCD.
• How many pairs of wires are used for the RS422 data. If there are two pairs of wire for each camera
you can probably assume half duplex. If only one pair it will be simplex only.
If the system is wired for duplex and the receiver dipswitches are set for duplex it will be necessary to make
sure the response data is fully functioning. If not you may encounter a problem with PTZ control. The
workaround would be to simply remove the response wires and set the PTZ receivers for simplex.
2. Pre-wiring. Telco blocks should be installed and wired for V1400X-IDL connections to facilitate a plug-and-play
migration of keypads and receivers to the V1500-CDU and should be used as part of the initial test procedure
to verify wiring.
3. The V1500CDU occupies the same amount of rack space (3RU) as either the VPS1300 or the VPS1400;
therefore the V1500CDU will fit in the same space. Placing it in the same space is important because of the
existing control cables.
4. The V1500CPU does not have to be co-located with the CDU because the only interconnection is the LAN.
5. The V1500CPU does need space for a VGA monitor and the keyboard and mouse.
6. If the system has two V1500CPU’s, a Keyboard-Video-Mouse (KVM) switch is recommended to simplify
operation.
7. The V1500CPU is 3.5” (2RU) high and 17.5” deep, excluding connectors. While it is designed to be rack
mounted, consideration should be given to supporting the rear of the chassis by some means in addition to the
front panel screws.
Installation Sequence (Hot Standby System):
Figures 3 and 4 show a “typical” rack layout for a VPS1400 hot standby system that will be used as an example. This
sequence provides for minimal system downtime.
1. Stage 1 (reference Figure 3)
a. Insure that the system is operating on the Primary VPS1400 CPU.
b. Remove any blank rack panels between the switchover modules (SSO, VSO, etc.) and the CPUs.
2. Stage 2 (reference Figure 3)
a. Without powering down any modules or disconnecting any cables, remove rack screws and lower the
switchover modules to just above the VPS1400 CPU.
b. Power down the secondary VPS1400 CPU and remove the interconnect cables. (NOTE: When
removing the cable from J5 of the Control Interface board [V1400X-CI], observe caution that the cable
pins do not contact ground. Doing so may cause the system to try to shift control to the now absent
secondary CPU.)
c. Install the V1500CDU and two V1500CPU’s where shown.
d. Make all LAN connections necessary between the units and connect the VGA monitor, keyboard and
mouse. Connect a Vicon keypad to the CDU.
e. Power up the new equipment and briefly test as before to ensure operation. Test switchover
capability.
f. Close any applications running on the secondary V1500CPU and power it off.
