  • Page 26: Synchronization In Redundant Systems

    EDUNDANT YSTEMS The 7750 SR-12 router is capable of a 1:1 Control Processor Module (CPM) redundancy scheme. Redundancy methods facilitate system synchronization between the active and standby CPMs so they maintain identical operational parameters to prevent inconsistencies in the event of a CPM failure.

  • Page 27: Ioms

    7750 SR-12 Overview 7750 SR-12 routers support a wide variety of interfaces, including Ethernet, SONET/SDH (channelized and concatenated), and ATM. Each I/O module (IOM) features a single-slot baseboard which can carry up to two hot-swappable MDAs with Small Form-factor Pluggable (SFP) optics, providing outstanding flexibility to mix-and-match interfaces per-slot as customer and network needs dictate.

  • Page 28: Chassis Components

    OWER EDUNDANCY At least one DC PEM must be installed in the 7750 SR-12 chassis to operate. An additional PEM can be installed for power redundancy. f you need to convert AC power to usable DC power, up to two rectifiers can be installed in the same AC power shelf and connected to a DC PEM.

  • Page 29: Table 5: Dc Power Entry Module Features

    NTRY ODULES DC PEMs are easily installed and removed from the rear 7750 SR-12 chassis power slots 1 and 2. One PEM can support the full system current requirements if you are operating the SR-12 without power redundancy. For redundancy, two PEMs must be installed and powered on at all times.

  • Page 30: Figure 5: 7750 Sr-12 Ac Power Rectifier (Example)

    AC-input power shelf. Each AC power shelf should be wired to a separate DC PEM installed in the 7750 SR-12 chassis. A maximum of two AC power shelves can be connected to a chassis when two DC PEMs are installed.

  • Page 31: Cooling System

    OOLING YSTEM The 7750 SR-12 system is cooled by hot-swappable impeller (fan) trays. A minimum of two impeller trays must always be installed and fully operational while the SR-12 is powered up. A third tray can be installed for redundancy. Each tray houses two impellers. The trays are accessed from the rear of the chassis and are interchangeable in any tray slot.

  • Page 32: Air Filter

    ANAGEMENT YSTEM The 7750 SR-12 chassis can accommodate 2 optional cable management trays. The trays are mounted on the front of the chassis, above and below the card slots. The cable management system manages the fiber optic cables so they do not interfere with the insertion or removal of IOMs and MDAs and prevents sharp bends which can damage the cable or degradate performance.

  • Page 33: Component Operating Requirements

    Only used for AC-to-DC power conversion. There is a 1:1 ratio of AC power shelf to DC PEM installed in an 7750 SR-12 chassis. A maximum of two DC PEMs can be installed in an SR-12 chassis, thus, only two AC power shelves can be used for the AC to DC conversion.

    OWER ECTIFIERS NOTE: For normal operation, the 7750 SR-12 requires at least two rectifiers in an AC power shelf. A third rectifier can be installed in the same shelf to provide redundancy. When three rectifiers are installed they equally power share the load. If a rectifier fails or if power is removed to a unit, the other two rectifiers power share the full load and maintain continuous system operation.
