  • Page 38: Mgx 8850 System Overview

    It maps all the service traffic to and from ATM by using standardized interworking methods. When the MGX 8850 switch operates as a feeder, it uses a single port to communicate the aggregated traffic over an ATM interface with an MGX 8850 or BPX 8600-series switch.

  • Page 39: Standards-Based Conversion To Atm

    DC or an AC source. MGX 8850 Cards The MGX 8850 switch supports two types of card sets: the core cards (or core modules) and service modules. The Processor Switching Module (PXM) and optional Service Resource Module (SRM) are core cards.

  • Page 43: Site Preparation

    This chapter describes the steps to take and the considerations you should keep in mind prior to installing the modules in an open rack. It also contains information that applies to an MGX 8850 installation in a Cisco closed rack. If the switch arrives in a Cisco closed rack, your initial concerns would be the cabinet grounding, power connections, and optional seismic stability plate.

  • Page 44: Site Preparation

    • Space The MGX 8850 node requires a floor area 19.9 inches (50.5 cm) wide or 23 inches wide (59 cm.). Sufficient clearance around the cabinet must exist for access to the front and back of the cabinet while the door is open. The suggested clearance is 30 inches at the front and back and a nominal 12 inches on each side.

  • Page 45: Seismic Considerations

    20A, 2-pole AC circuit breaker with a long trip-delay at each branch circuit. The MGX 8850 nodes use a 20A, 2-pole circuit breaker for each AC input. The manufacturer of this circuit breaker is ETA, and the ETA part number for the circuit breaker is 8340-F120-P1P2-B2H020A.

  • Page 46: Telecommunications Requirements

    As recommended in these documents, a frame bonding connection is provided on the Cisco cabinet for rack-mounted systems. To see how to make a connection, see “Making the Frame Bonding (Ground) Connection” later in this chapter.

  • Page 47: Figure 3-2 Stability Plate Dimensions

    To set up the Cisco cabinet with the stability plate, perform the following: Use the dimensions in Figure 3-2 to drill the holes for installing the stability plate. Step 1 Remove the stability plate from the base of the Cisco cabinet. Save these nuts and bolts. Step 2 Step 3 With the user-provided anchoring bolts, attach the stability plate to the floor.

  • Page 54: Mounting Features

    Each module has flanges that serve as the front mounting brackets in a 19-inch rack. For a 23-inch rack, Cisco Systems provides special brackets. The 19-inch rack version appears in Figure 4-1. You can attach the enclosure modules to the mounting rails at the following points on the enclosure modules: •...

  • Page 55: Mounting The Mgx 8850 Modules

    This section describes how to install the mandatory and optional modules that make up the enclosure of the MGX 8850 switch. For open rack installations, Cisco advises you to remove the cards and AC power supplies before installing the switch, so this section also contains the steps for removing and installing these items.

  • Page 56: Removing A Front Card

    Mounting the MGX 8850 Modules If you use a power-screwdriver, do not use it on any of the captive screws. Caution When moving a Cisco-supplied cabinet, do not push the cabinet at its sides. Instead, grip Caution its front or back edges.

    SRMs occupy these reserved slots. Additionally, upper slots 9 and 10 and lower slots 25 and 26 do not have a special bus for the bulk distribution feature. For this reason, Cisco recommends that if the switch contains RPMs, the first two RPMs go in slots 9 and 10.

  • Page 95: Redundancy For Frame Service Modules

    Redundancy for Frame Service Modules Redundancy for Frame Service Modules FRSMs can have either 1:1 redundancy or 1:N redundancy. For 1:1 redundancy, a Y-cable is necessary. The very high speed MGX-FRSM-2CT3, MGX-FRSM-2T3E3, and MGX-FRSM-HS2/B use Y-cable redundancy. For 1:N redundancy, an MGX-SRM-3T3/B and no Y-cabling are required. Differences may exist in the way the MGX-SRM-3T3/B supports redundancy for a particular T1 or E1 configuration.
