IP Network Requirements
IP Network Requirements
As shown on page 83 and page 84 , the IP switch used in Maestro installa-
tions should be divided into four VLANS (for Encore systems) or three
VLANs (for Jupiter systems).
For this application, Grass Valley recommends the Hewlett Packard Pro-
Curve 2610 48-port, 10/100 Layer 3 managed switch.
This switch replaces the obsolete Hewlett Packard ProCurve 2626 and 2650
switches.
Both 1 RU switches measure 17.32 x 12.8 x 1.75 in. (43.99 x 32.51 x 4.45 cm).
(For product details, go to http://www.hp.com/rnd/products/switches/
switch2600series/overview.htm).
IP Routing (forwarding) is enabled to permit inter-network communica-
tion. The switch must allow IP multicasting.
Using the Spanning Tree Protocol
Using the Spanning Tree protocol or the Rapid Spanning Tree Protocol
(RSTP) may inhibit communications between the Maestro processor and
the Deployment PC during startup, especially if communication paths are
not established within 15 seconds. This communications deterrence can
result in startup and hot-swap issues and other Maestro network problems.
All ports should be configured for the auto-negotiate mode.
The deployment of the Spanning Tree protocol within network switches
may result in excessive delays before the required communication paths,
which must be reliable and available, have been established. The Maestro
Frame Processors and Panel Servers will attempt to communicate with the
Maestro Deployment PC approximately 15 seconds after a Power On or
Reset operation. A stable and available communications link is required for
the boards to function properly.
Maestro users that make use of the Spanning Tree protocol must assume all
risk and liability including, without limitation, lost profits, business inter-
ruption, or lost information.
