Connecting to the 10/100/1000 Ports

Connecting to the 10/100/1000 Ports
The 10/100/1000 ports configure themselves to operate at the speed of attached devices. If the attached
ports do not support autonegotiation, you can explicitly set the speed and duplex parameters. Connecting
devices that do not autonegotiate or that have their speed and duplex parameters manually set can reduce
performance or result in no linkage.
To maximize performance, choose one of these methods for configuring the Ethernet ports:
•
•
Follow these steps to connect to 10BASE-T, 100BASE-TX or 1000BASE-T devices:
To prevent electrostatic-discharge (ESD) damage, follow your normal board and component handling

procedures.
When connecting to workstations, servers, routers, and Cisco IP Phones, connect a straight-through
Step 1
cable to an RJ-45 connector on the front panel. (See
repeaters, use a crossover cable. (See the
cable-pinout descriptions.)

When you connect to 1000BASE-T-compatible devices, be sure to use a twisted four-pair,
Note
Category 5 cable.
Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on
Step 2
when both the blade switch and the connected device have established link.
The port LED is amber while Spanning Tree Protocol (STP) discovers the topology and searches for
loops. This takes about 30 seconds, and then the port LED turns green. If the port LED does not turn on,
the device at the other end might not be turned on, or there might be a cable problem or a problem with
the adapter installed in the attached device. See
problems.

Let the ports autonegotiate both speed and duplex.
Set the port speed and duplex parameters on both ends of the connection.
