Vanguard 7300 Cards
PCI Mezzanine Card (PMC)
Introduction 10/100BaseT Ethernet Mezzanine Cards (PMCs)can be installed in the PMC slot on
the CPU card and in the two PMC slots on the Carrier Expansion Card. Because a
PMC does not require a full slot, it is mounted on a full-size card that serves as its
host. The following full-size Vanguard 7300 cards can host PMCs:
• CPU Card (one PMC slot)
• Carrier Expansion Card (two PMC slots)
Dual-port 10/100BaseT Ethernet Mezzanine Card (PMC)
Description The 10/100BaseT Ethernet Mezzanine Card (PMC) mounts on the CPU card and
on the Carrier Expansion Card. This 10/100BaseT Ethernet PMC provides two
auto-sensing ports that can switch between 10BaseT and 100BaseT, depending on
the link
data rate, to provide the highest possible 10 or 100 Mbps throughput.
An auto-sensing port detects the speed of hubs and adapters and negotiates
automatically
for the maximum possible throughput speed. The Vanguard 7300
Ethernet interface complies with the IEEE 802.3 for 10BaseT and 100BaseT.
Front View The 10/100BaseT Ethernet PMC provides two RJ45 connectors and six indicator
LEDs on the
front panel as shown in Figure 2-15:
