IQH4B enclosures offer industry-leading, high-density delivery of modular solutions. With up to 700W of module power available this 4 RU enclosure accepts up to 20 modules, has dual redundant PSUs and in-service replaceable cooling fans. Analog reference signals can be distributed through the enclosures via two connections that can be independently selected by the installed modules. RollCall control and monitoring is included as standard using a gateway control card that has its own module-style rear connector, thus providing a future-proof upgrade path as communication standards evolve. Full SNMP control and monitoring functionality is also available over Ethernet.
20 single- or 10 double-width modules (or any combination)
Integrated web browser-based RollCall configuration and control
SNMP control and monitoring of ALL RollCall-enabled IQ modules as standard
Dual redundant network architecture over Ethernet and RollNet enables mission critical control applications to function even if a complete network failure occurs
Plug-in gateway communications card to enable RollCall via RollNet, RS-232/485/422 and RollCall over TCP/IP control, with support for upgradeable connectivity to handle future communication standards
2x analog reference signal distribution for dual standard (Bi-Level or Tri-Level), dual video standard (SD or HD), and reference redundancy applications (Note: Only applicable to modules with -B order codes)
Hot swappable redundant power supplies and in-service replaceable fan units
Optimum use of rack space — frames do not require any additional ventilation spacing
Variable fan speed, dependent upon load and ambient temperature
Full chassis monitoring, including inlet and outlet temperature, PSU, fan and module status
Unit address code set switches: 2 Hex switches 0 to F
Communications mode switch: Select RS-232, RS-485 or RS-422 interface
Additional Controls via RollCall Remote Control System
Full control via web browser-based Java RollCall control panel (available from chassis), any hardware RollCall control surface or standard RollCall Control Panel PC Application.

Ethernet/SNMP compatible RollCall Gateway card for IQH4B and IQH3B enclosures.
Notes: Although IQ modules are interchangeable between enclosures, each enclosure requires a suitable variant of panels
Either ‘A’ or ‘B’ order codes may be used when installing approved modules in IQH4B enclosures
The IQH4B enclosure is primarily for use with IP modules. Please check with your authorized Grass Valley representative for an updated list of other approved IQ modular cards for the IQH4B enclosure
‘A’ build rear panels will fit into IQH4B enclosure, however features such as frame reference (if relevant to the module) would not be supported by those modules
