Model 6511RC User Manual 1 • Introduction
- The PICMG 2.16 packet-switched bus (PSB). In order to manage the Matrix Switch in-band via the
PICMG 2.16 PSB, an external management workstation connects to the ForeFront chassis via another
ForeFront blade with management routing capability, such as the Model 6801RC EdgeRoute Network
Access Server or model 3096RC TDM Digital Access Concentrator, operating on the same bus. The
external management workstation communicates with the ForeFront system using either a Frame Relay
or PPP link within a DS0 or within an Ethernet link. The in-band management link terminates on the
module with management routing capability, which in turn communicates with the management services
in the Matrix Switch over the PICMG 2.16 PSB.
• Out-of-band management access paths include:
- The RS-232 config port on the front panel of the front blade
- The RJ-45 10/100 Ethernet LAN port on the front panel of the front blade
- The two RJ-45 10/100/1000 Ethernet LAN ports on the rear panel of the rear blade, in applications
where these Ethernet links are dedicated to management traffic.
Matrix Switch Interfaces
WAN Interfaces
The 6511RC provides connections to the following WAN interfaces:
• One SDH STM-1 uplink trunk port at 155.54 Mbps
-Physical SC or BNC connectors presented on the rear-blade rear panel
• Two Ethernet trunk ports at up to 1 Gbps
-Physical RJ-45 connectors presented on the rear-blade rear panel
The STM-1 WAN uplink port may be connected to an SDH network via the Optical SC ore electrical BNC
connectors presented on the rear blade.
Mid-Plane Interfaces
• Connection to the H.110 Time-Division Multiplexed bus providing 4096 DS0 channels of 64 kbps each
-Physical and electrical connections via the mid-plane connector block on the rear of the front blade
• Connection to the PICMG 2.16 Packet-Switched Bus (PSB)
-Physical and electrical connections via the mid-plane connector block on the rear of the front blade
LAN Interface
The 10/100-Mbps Ethernet LAN port is presented on an RJ-45 connector with an auto-sensing/full-duplex
10Base-T or 100Base-T interface. Also included are:
• 100Base-TX half-/full-duplex operation (100 + 100)
• 10Base-T half-/full-duplex operation (10 + 10)
• Auto detection and fallback
• 10/100 Mbps link and status indicators
