Sub-Master (Slave) Network Time Server 7001(RC)-Slave with NTP LAN Board(s) 7273(RC) / 7274(RC)

Short Description

By implemenation of NTP LAN Board(s) 7273(RC) or NTP LAN Board(s) 7274(RC) (10/100/1000 Mbit/s autosensing, VLAN, Bonding, PRP) System 7001(RC)Slave becomes a highly accurate NTP Stratum 1 Time Server for synchronization of computers and industrial networks.

System 7001(RC)Slave can either be delivered with NTP LAN Board(s) 7273(RC) / with NTP LAN Board(s) 7274(RC) from the factory or subsequently extended by board(s) 7273(RC) / 7274(RC) in the field.

  • System 7001-Slave: up to 8 NTP LAN Board(s) 7273 / 7274 implementable
  • System 7001RC-Slave: up to 31 NTP LAN Board(s) 7273RC / 7274RC implementable

The modular design structure of system 7001(RC)-Slave also allows the combination of one board 7273(RC) / one board 7274(RC) with any other function board suitable for system 7001(RC)-Slave.


Features of Base System 7001(RC)-Slave

  • Sub-Master System to be modularly equipped with a synchronisation board and function boards
  • High availability based on hot-plug capability:
    • Removal and installation of function boards during operation
    • Failure of single function boards do not influence the functions of the other boards
  • Channels for parameterization/monitoring:
    • Keypad and operating menu via display
    • Serial connection via the hmc (hopf Management Console)
    • WEB-GUI and SNMP for function boards with LAN interface
    • Option: LAN connection via the hmc including monitoring via SNMP
  • Subsequent extension by additional function boards
  • Error-Management to be parameterised
  • SyncOFF Timer (bridging of reception failure) providing an error-free operation even under difficult reception conditions
  • Redundant multiple test mechanism of the synchronisation signal providing a correct and leap-free signal evaluation
  • High free running accuracy
  • Maintenance-free back-up clock for three days
  • System completely maintenance-free
  • Options:
    • Power supplies for various operating voltages
    • Multi source functionality:
      Synchronisation via an additional signal input with automatic switch-over between GPS and the second synchronization source
    • Supply in 6U (6U/84HP) or 9U (9U/84HP) rack for implementation of more function boards and/or more extensions slots
    • Redundant power supplies
    • OCXO crystal basis for increased free running accuracy
    • Status LEDs in the front panel
    • Extension by a Switch-Box (System 5000) for automatic switch-over of signals between two systems
  • Specific hardware and software customizations

Features of NTP/SINEC H1 LAN Board 7273(RC)

  • Alarming
    • SNMPv2c / SNMPv3 (MIB II, hopf Private Enterprise MIB, SNMP traps)
    • E-Mail Notification
    • SYSLOG
  • Routing for configuring static routes based on special network configuration requirements
  • SINEC H1 time datagram

Features of NTP/SINEC H1 LAN Board 7274(RC)

  • all features of NTP/SINEC H1 LAN Board 7273(RC)
  • 2 ethernet interfaces 10/100/1000 Mbit/s autosensing
  • Activation options:
    • VLAN support according to IEEE 802.1q
    • Port aggregation (NIC Bonding/Teaming) with support of IEEE 802.3ad trunks
    • Parallel Redundancy Protocol (PRP) according to IEC 62439-3
    • Precision Time Protocol (PTP) according to IEC 1588


According to the customer specifications, the base system 7001(RC)-Slave is equipped with a synchronisation board and/or additional hardware input depending on the used signal and with function boards for the output of required signals. The possible number of functions boards to be integrated and upgraded is primarily determined by the number of available slots in 19" rack and the power supply capacity.

Please note:

  • Board number _ _ _ _ RC: only available for system 7001RC
  • Board number _ _ _ _ (RC): available for system 7001 as well as system 7001RC
  • Board number _ _ _ _ : only available for system 7001
