Major Xedge 6000 Hardware Components
Xedge Chassis Systems
An Xedge chassis system includes the rack-mountable shelf and one or more power supplies. GDC
manufactures a variety of Xedge chassis, listed below. Note that the information in this manual
applies to earlier APEX versions of the chassis, except where noted.
•
Xedge 6002 AC Chassis - one or two slot controllers.
•
Xedge 6160 AC or DC chassis - up to 4 slot controllers. (formerly “APEX MAC1”)
•
Xedge 6280 AC or DC chassis - up to 7 slot controllers. (formerly “APEX IMX”
•
Xedge 6640 AC chassis - up to 16 slot controllers. (formerly “APEX DV2”)
•
Xedge 6645 DC chassis - 16 slot controllers. (formerly APEX NPX”)
Xedge Switch Fabric Modules
In higher density Xedge switches (Xedge 6640, 6645, 6280, 6160), one or two Xedge Switch Fabric
modules plug into dedicated slot(s) at the front of the chassis, labeled SF Main and SF Standby. The
switch fabric is responsible for transporting cells simultaneously to up to 16 slot controllers in the
switch at 400 Mbit/s throughput in each direction.
•
XM Switch Fabric (1.6 Gbps) supports up to 4 slot controllers.
•
XS Switch Fabric (2.8 Gbps) supports up to 7 slot controllers.
•
XH Switch Fabric (6.4 Gbps) supports up to 16 slot controllers.
Note
The Xedge 6002 has no provision for switch fabric modules since it is designed for packet controllers which
have integral switch fabric sufficient for that 1 RU chassis.
Note
In any higher density chassis, the switch fabric used is determined by the number of slot controllers in the
chassis, as shown in
.
System Modules
SMM - System Management Interface Module
•
Installs in a dedicated slot at the rear panel of Xedge 616 or Xedge 6280 chassis only.
•
Provides craft port access
•
Provides environment alarm monitoring
STM - System Termination Module
•
Required in Xedge 6640 or 6645 chassis with four or fewer slot controllers.
•
Installs in the Standby slot-0 position of the Xedge 6640 or Xedge 6645.
(STM disallows slot-0 redundancy in its switch.)
•
Monitors and conditions the system clock signals.
NTM - Network Timing Modules
•
Installs in dedicated slots at the rear panel of Xedge 6280, 6640 or 6645 chassis.
•
Two NTM versions (DS1 or E1) provide increased control options for system timing.
•
Requires LIMs that have software selectable data clocks ("enhanced" clocking LIMs).
Note
for chassis/module compatibility.
