IQH1A 1RU Frame

The IQH1A enclosure offers high-density delivery of HD and SD modular solutions. The 1 RU enclosure accepts up to four “A” & Now “B” style modules and is available with hot-swappable dual redundant PSUs for maximum reliability. The enclosure is fitted with RollCall control and monitoring as standard, including full SNMP control and monitoring functionality over Ethernet.


  • Four single-width or two double-width modules (or any combination)
  • Capable of accepting all types of IQ modules including HD-SDI, SD-SDI, AES and analog audio, analog video and fiber optics
  • Dual redundant power supplies (hot swappable) for high system availability
  • Optimum use of rack space — frames do not require any additional ventilation spacing
  • Plug-in RollCall enabled via gateway card with TCP/IP, RollNet, SNMP and RS-232/422 connectivity
  • In service replaceable cooling fans
  • Chassis monitoring, including inlet temperature, fan condition and module status
  • Full CE and UL compliance

Enclosure with Dual Redundant PSU & Ethernet/SNMP Compatible RollCall Gateway Card. 4 module slots.

Single PSU as cold spare or upgrade to Dual PSU configuration.

Ethernet/SNMP compatible RollCall Gateway card for IQH1A 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 modules in the newer IQH1A enclosures
  • When selecting ‘B’ build rear panels to fit into the IQH1A enclosure, please ensure features such as frame reference (if relevant to the module) are available on the rear since distributed reference is not supported in this enclosure
