Electrostatic Discharge (ESD) Protection
Electrostatic discharge occurs when electronic components are improperly handled and can result in
intermittent failure or complete damage adversely affecting an electrical circuit. When you remove and
replace any card from a frame always follow ESD-prevention procedures:
•Ensure that the frame is electrically connected to earth ground through the power cord or any other means if
available.
•Wear an ESD wrist strap ensuring that it makes good skin contact. Connect the grounding clip to an unpainted
surface of the chassis frame to safely ground unwanted ESD voltages. If no wrist strap is available, ground
yourself by touching the unpainted metal part of the chassis.
•For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and
10 megohms.
•When temporarily storing a card make sure it is placed in an ESD bag.
•Cards in an earth grounded metal frame or casing do not require any special ESD protection.

1 IPG-4901 WAN IP I/O Gateway for GV Node
1.1 Introduction
The GV Node IP Gateway (IPG-4901) plug-and-play module from Grass Valley, a Belden Brand, is a 3 RU single slot
module for the GV Node frame, which offers bidirectional fiber IP connectivity.
Not all IP signals are created equal. While Grass Valley provides a very complete IP solution, there will still be
requirements to provide conversion to/from other equipment that supports IP standards that are incompatible. The
IPG-4901 IP Gateway provides a robust feature set for normalizing variances in IP signals sent to GV Node or GV
Matrix I/O.
WAN IP connectivity: The IPG-4901 leverages the full SMPTE ST 2022-7 Class A specification to ensure
uninterrupted reception of high jitter signals from remote sources and SW based transmitters. The IPG-4901 can be
fitted with multimode or singlemode SFPs to provide connectivity up to 10 km (6.21 mi.).
Signal conversion with audio DEM/EMB: In conjunction with the GV Node 40G aggregation ports, the IPG-4901
can be used to convert SMPTE ST 2022-6 and AES67 signals from the WAN to SMPTE ST 2110-20/30/40 signals on
the LAN. Each IPG- 4901 module has bidirectional 10G Ethernet ports that support up six 3 Gb/s sources or nine HD
sources with AES67 audio DEM/EMB.
Signal Alignment: The IPG-4901 provides a full alignment capability with up to two frames with respect to the GV
Node switching fabric, and is available for any SMPTE ST 2022-6 signals and AES67 audio, in both aggregation and
redundancy modes.
Alignment capability provides a clean switching of any of the sources from the IPG-4901.
The IPG-4901 I/O module may be combined in the same chassis with other GV Node or GV Matrix modules to create
an even more versatile distributed edge-routing node.
The GV Node IP Gateway can be controlled by the advanced GV Convergent SDN platform, offering unified control
across COTS IP switches and SDI routing/processing infrastructures, as well as by the proven iControl systems.
1.2 Features
•Two dual-network interfaces supporting 10 GigE SFP+ ports with either:
oLong range single-mode optical connectors.
oShort range multi-mode optical connectors.
•In aggregation mode each module connects up to 6x6 3G or 9x9 HD SMPTE ST 2022-6 video sources along
with AES67 de-embedding/embedding of up to 16 audio channels per source.
oAugments SMPTE ST 2022-6 video payload with individual audio streams using VSF TR-04.
oSupports bursty server-originated sources with SMPTE ST 2022-6 core.
•In redundancy mode each module connects up to 3x3 3G or 5x5 HD video sources along with AES67 de-
embedding/embedding of up to 16 audio channels per source.
oFull compliance to SMPTE ST 2022-7 Class A of all IP essences.
•Input signal alignment with up to 2 frames.
•Support of PTP on the media port with fail-over redundancy for AES67 streams. Supports both AES67 and
SMPTE ST 2059 profiles.
•Support of DiffServ for network traffic provides categorization of flows into QoS classes.

2 Installation
2.1 Installation of Rear Connector Panel
The IPG-4901 card is designed to fit into Grass Valley’s GV Node IP aggregation, processing and edge routing
platform. Each modular card designed for this platform is associated with a rear connector panel that provides both
internal and external connectivity for the card.
A single rear connector panel is available for the IPG-4901:
•IPG-4901-4SRP Single-slot-width panel for GV Node
The card and the rear panel can be installed with the frame power on.
The rear connector panel must be installed with the card out of the frame.
To install the connector panel:
1. If a card is installed in the slot whose rear panel is being changed, remove it by tilting the swivel handle on the
front of the card to lever the connectors apart, then using the handle to pull the card straight out of the slot.
2. Remove the existing rear panel (either blank or belonging to an existing card that is being changed) by
releasing the captive screw at the bottom of the panel.
3. Position the new panel and secure it in place with the captive screw(s) at the bottom.
2.2 IPG-4901 Card Installation
Once the rear connector panel is in place, install the IPG-4901 card as follows:
1. Open the front door of the GV Node frame.
2. Slide the IPG-4901 card into the slot (swivel handle at the top) and push gently on the handle to seat the
connectors.
3. Close the front door of the frame.
2.3 Rear Panel Layout and Connectors
Two 10 Gb Ethernet interfaces (each with Tx and Rx) on optical fiber or twinax cable. SFP+ modules and matching
fiber or electrical connectors are required for the interface.

3 Local control using the GV Node’s control panel
The GV Node’s local control panel is fastened to the front of the controller card, and accessed through an aperture in
the frame door.
To access the menu for this IPG-4901, touch the virtual button corresponding to the card (identified by card type and
slot number) in the home screen.
The control section of the panel displays two lines of text, each 16 characters in length, and four virtual pushbuttons.
The functionality of the pushbuttons is as follows:
[+] [–] Used for up/down menu navigation and value modification
[SELECT] Gives access to the next menu level. When a parameter value is shown, pushing this button once
enables modification of the value using the [+] and [–] buttons; a second push confirms the new value
[ESC] Cancels the effect of parameter value changes that have not been confirmed; pushing [ESC] causes the
parameter to revert to its former value.
Pushing [ESC] moves the user back up to the previous menu level. At the main menu, [ESC] does not
exit the menu system. To exit, re-push the [SELECT] button for the card being controlled.
If no controls are operated for 30 seconds, the controller reverts to its normal standby status, and the selected card’s
STATUS reverts to its normal operating mode.
Use the control panel buttons to navigate through the menu, as described above.
•The complete menu structure is shown in ANNEX 1 – Local Menu, beginning on page 38.

Stream Address:
•When ETH2 is disabled or in Aggregation mode, we only have one IP stream associated with each Gateway.
•When ETH2 Operation mode is set to Redundancy, we have two IP streams associated with the Gateway –
Primary Stream and Redundancy stream. The gateway will be linked to the primary stream when it is valid. If
the main stream is in error, the gateway will fall back to the redundancy stream. The fallback may generate an
error on the SDI output.
Stream Port: Shows the port associated with the stream. Edit the port by selecting the text and typing a new value.
IGMPv3 Source: On IN-to-fabric (gateways 10-18) we have an additional setting: IGMPv3 source. This is used when
receiving multicast streams. In this protocol, the card deals with a switch to subscribe to one or many streams that are
coming from different IP addresses.
•When receiving multicast streams, the “stream address” is used to talk to a “group” while the “IGMPv3 source”
indicates the exact source from which we want to receive the stream.
•When receiving unicast streams, IGMPv3 protocol is not used.
•When this field is set to 0.0.0.0, IGMPv3 protocol will request multicast streams for all sources.
Type directly into the data boxes to enter stream addresses and port numbers.
