*’U’ numbers are printed on the rack rails of the OP-HUB2 rack.
Hub Racks are numbered sequentially: Rack1, Rack2, and so on, or by serial number. The
following guidelines apply:
• Chassis in Hub racks are numbered by ‘U’ number. For example, the lowest RF chassis
shown in Table 4 would be numbered U12.
• BIMs in racks are numbered by ‘U’ number. For example, the lowest BIM shown in
Table 4 Would be numbered U8.
• Power Attenuators are located at the top of the Hub rack or mounted to a wall.
• WSP Base stations should be given unique Tenant Name and BTS ID designations.
• Each base station sector is cabled to a separate attenuator and BIM unit in the Hub rack.
2.2 MIB Relationships
As explained in Section 1.4.2 on Page 4 , the Digivance CXD/NXD system uses Management
Information Bases (MIBs) accessed with an SNMP manager (or EMS) to provide a user
interface for querying and configuring perrformace objects and being notified of alarms. This
section describes the relationships between MIBs that are relevant when cofiguring and
operating the system.
