Connecting PMC Network Interface Cards
68 Nokia 500s Installation Guide
Note
Any two NICs installed on a single PMC carrier will both operate at the
PCI frequency of the least-capable NIC installed. For example, if a dual-
port Ethernet NIC and a dual-port fiber-optic Gigabit Ethernet NIC are
installed on the same PMC card carrier, they both operate at 66 Mhz. Use
this information to plan your NIC installation to maximize data throughput
on your appliance.
Caution
To protect the 500s appliance and the memory modules from
electrostatic discharge damage, make sure you are properly
grounded before you touch these components. Use a grounding
wrist strap and follow the instructions provided with the wrist strap
before you handle the components or open the appliance. If you do
not have a grounding wrist strap, make sure you are properly
grounded before you touch any electronic component.
Four-Port and Dual-Port 10/100 Ethernet NICs
The 500s appliance supports Nokia-approved, four-port and dual-port UTP5
dual-mode (10-Mbps and 100-Mbps) Ethernet NICs installed in a 6U PMC
carrier. When you purchase a 10/100 Ethernet NIC with your 500s appliance,
the NIC is installed before the appliance is delivered to you. For information
