Metrodata’s MetroRack presents you with a modular delivery platform offering centralised status checking and high module density for the efficient use of limited rack space.

MetroRack: Centralised Management Chassis

MetroRACK: Modular Delivery Platform

  • Centralised management in a single rack solution
  • Multiple I/O module options available in a single rack
  • Compact 4U 19” rack spacing
  • 12 slot chassis unit with SNMP management card
  • 13 slot chassis unit without SNMP management card
  • Alarm extension relays
  • Hot-Swap for all modules & power supplies
  • SNMP remote management
  • Cost effective solution to multiple interface requirements
  • Redundant load sharing PSUs for increased resilience

Service Delivery of Management Services using the MetroRACK and WC1000 modules along with standalone WC1000 units

MetroRack for Delivery of Management Services

This application shows how a MetroRACK chassis fitted with WC1000 modules can be used in an exchange/POP along with standalone WC1000 units to deliver a management connection to the customer site using spare E1 capacity of the ADM.

E1 Service Delivery over Fibre using the Emux in conjunction with MetroRACK fitted with FC1000 modules and multiple FC1000 standalone units

Emux and MetroRack to deliver E1 services over fibre

This application shows how a MetroRACK chassis fitted with FC1000 modules can be used in conjunction with an Emux in an exchange/POP along with standalone FC1000 units to deliver multiple E1 services over a fibre infrastructure.

The MetroRACK is a 4U high, 19” rack based chassis unit supporting up to 2 power supply modules (PSUs) and has 13 available slots that can accommodate the SNMP management module and a selection of I/O interface modules. Spare Modules can be resident in the chassis ready for immediate additional functionality or to provide ‘in situ’ spares. Ease of maintenance and the provisioning of new services is fulfilled through the modules and power supplies being “hot swap” compliant.

The MetroRACK only requires a single PSU to support a full rack of cards but for increased resiliency redundant PSUs can be used. The PSUs are load sharing when used in the optional 1+1 redundant configuration. For maximum MTBF (mean time between failures) the -48V DC PSU modules may be used. Typical operating power consumption is less than 75 watts.

The I/O Modules for MetroRACK support the core standalone operation of each I/O module by simple bit switch configuration, but when the optional Management module is fitted, a fully managed chassis including SNMP capability is realised.

Management of the MetroRACK is either via the console port, or the management Ethernet port using SNMP or Telnet. SNMP version 1 is supported, including MIB-2 and Traps. SNMP traps are generated based on configurable alarms generated for any of the I/O Modules. TFTP download of software and configuration is also supported. To further future proof the MetroRACK system, remote hardware upgrade of CPLD firmware is included. Management access has password protection whether via the console or Telnet. Performance statistics are available for all ports with data collection in 15 minute segments for a 24 hour period.

The 2 left hand slots are double width and are used for the power supply modules. If only one power supply is fitted, then the other power supply slot is not available for I/O modules, but must have a blanking plate fitted for EMC compliance. A Manager module may occupy the first single width slot, or alternatively this can be used for an I/O module. The subsequent slots provide space for up to 12 I/O modules. Any unoccupied slots must have blanking plates fitted for EMC compliance.

The following specifications relate to the MetroRACK Chassis without any interface modules fitted. Each individual module also has its own specifications, check each module for further information.
