1 Introduction
This Configuration Guide describes how to configure ASL NETWORK-SWITCH-LP01 for use in an ASL
PAVA system. It covers fault reporting, SFP speed, ASL Secure Loop (RSTP), and additional configuration
for systems that include VIPEDIA-12-PRO and/or INTEGRA-PRO units.
The instructions in this document are correct for network switch software V1.0.1.S0. Newer or older software
may provide different features or have different configuration options.
Features not covered in this Configuration Guide are covered in the NETWORK-SWITCH-LP01 User
Manual. For access, go to the ASL website at www.asl-control.co.uk or scan the QR code on page 2.
1.1 Port Capabilities
NETWORK-SWITCH-LP01 has the following port capabilities:
•8 x RJ45 copper 10/100 Mbps connection speed.
•2 x SFP 100/1000 Mbps connection speed.
1.2 Required PC Tools and PC Configuration
NETWORK-SWITCH-LP01 configuration requires:
1. A PC (Windows 10) with the network interface configured correctly to communicate with the network
switch.
For instructions, refer to section 4 APPENDIX – PC Requirements on page 23.
2. A web browser.
1.3 Systems Containing VIPEDIA-12-PRO and/or INTEGRA-PRO
The NETWORK-SWITCH-LP01 is compatible with systems containing VIPEDIA-12-PRO and/or INTEGRA-
PRO units where the overall network traffic is no greater than 30 Mbps. This includes all traffic from the ASL
system, non-ASL equipment, and Dante.
Use the following figures to estimate the overall network traffic:
1. Each Dante multicast flow is between 3 Mbps (containing 1 channel, the minimum) to 11 Mbps
(containing 8 channels, the maximum).
2. Each Dante unicast flow is approximately 6 Mbps (containing up to a maximum of 4 channels).
3. Each ASL audio stream (over PMC)1is approximately 1 Mbps.
To estimate the overall network traffic, add the expected number of Dante multicast and unicast flows to the
expected number of concurrent ASL audio streams.
Other network traffic has negligible impact on the overall network traffic.
1ASL audio sources are routed to remote units over IP using ASL's PMC format.

VIPEDIA-12-PRO and/or INTEGRA-PRO audio inputs configured as Dante are automatically
configured as multicast flows when using the “Export Dante Controller File” feature in the PAVA
System Configuration Tool.
If all twelve inputs are configured, the first eight inputs are in one Dante multicast flow (approx.
11 Mbps) and the next four are in a second Dante multicast flow (approx. 5 Mbps), giving 16 Mbps
traffic.
Note that an input routed over Dante to remote units is also routed over PMC.

2 Wiring and Hardware Settings
2.1 Wiring
2.1.1 Power
Refer to the NETWORK-SWITCH-LP01 User Manual for the voltage range and wiring instructions for the
primary and, if required, the secondary power supply.
2.1.2 Ethernet
All NETWORK-SWITCH-LP01 units have the same factory default IP address, 192.168.2.5. The default
netmask is 255.255.255.0.
2.1.3 Fault Relay
The NETWORK-SWITCH-LP01 fault relay should be connected to an onboard or BMB01 fault contact input
in the PAVA system, and the network switch configured to report power supply and Ethernet connection
faults.
For wiring instructions for the fault relay, refer to the NETWORK-SWITCH-LP01 User Manual and the
relevant ASL product documentation
For the network switch fault relay configuration, refer to section 2.2.1 Fault Reporting on page 5.
For PAVA system onboard or BMB01 fault contact input configuration, refer to the relevant ASL product
documentation.
For EN 54-16 compliance, a separate power supply must be connected as a secondary power
source.
Do not connect network switches together until the configuration in section 3 Configuration on
page 7 is complete for each unit.
This is to prevent configuration issues due to multiple network switches with the same IP address,
and to prevent data storm due to RSTP being disabled by default.
For EN 54-16 compliance, the fault relay must be connected and configured as described above.
The PAVA system fault contact input must be configured to active low.

2.2 Hardware Settings
2.2.1 Fault Reporting
The network switch should be configured to monitor the Ethernet connections and power supply. This is
configured using DIP switches on the top of the unit.
1. Ensure switch 1 (PWR) and switch 2 (RPS) are ON.
2. Set switches 3 (P1) to 12 (P10) ON for each port that has a connection to the ASL Secure Loop, or
to a device that is part of the PAVA system.
The example below is configured for ASL Secure Loop connected to ports 9 and 10 (the SFP ports) and
VIPEDIA-12 connected to port 1.
For EN 54-16 compliance, the network switch must be configured to report faults as described
above and connected to an onboard or BMB01 fault contact input in the voice alarm system.
The PAVA system fault contact must be configured to active low.
