Figure 19. BNC coaxial cable connectors
Do the following to connect the dual 75-ohm coaxial cable (see figure 19) to the STM-1 BNC connectors:
1. Attach the transmit connector of the coaxial cable to the TX connector on the rear blade (see figure 14 on
page 35).
2. Attach the transmit connector of the coaxial cable to the RX connector on the rear blade.
Connecting the rear-panel Ethernet WAN/management ports
The Matrix Switch provides two 10/100/1000Base-T Ethernet transceivers, accessible via physical interfaces
on the rear-panel of the rear blade, for connection to an external router, hub, or switch. Both interfaces are pre-
sented on RJ-45 6-pin female receptacles. The interfaces comply with IEEE specification 802.3 and are labeled
ENET 1 and ENET 2 (see figure 14 on page 35).
Once connected to a LAN, the Ethernet port will autosense the speed of the LAN and automatically negotiate
half or full-duplex operation. The ports provide access to the Matrix Switch’s resident management services,
including the HTTP/web management feature. This port also connects to the on-board Ethernet switch, thus
providing Ethernet access to other blades within the ForeFront system via the PICMG 2.16 PSB.
You can use the two high-speed Ethernet ports to implement the following functions:
• Ethernet trunks. You can connect the 10/100/100 Ethernet ports to a WAN router in order to deliver
high-speed aggregated packet-based traffic to and from the ForeFront system over packet-switched WAN
trunks. The WAN router would then be connected to a private WAN or to the Internet.
• Ethernet management network. You can connect the 10/100/100 Ethernet ports to a local area network
via an external hub or switch in order to implement an out-of-band management network. To create an
external management network, all ForeFront blades must connect to the management LAN via an Ethernet
port residing on each blade. The Matrix Switch also offers access to an internal management network, the
PICMG 2.16 PSB. By means of its on-board Ethernet switch, the Matrix Switch provides a packet-switched
path to all blades operating on the same PICMG 2.16 bus, which a Network Management System can use
to communicate with the management services on those blades.
