Table 1 describes the Cisco Catalyst Blade Switch 3120 for HP switch module ports. Each external port has an associated LED.

Table 1 Cisco Catalyst Blade Switch 3120 for HP Port Descriptions

Port

Description

 

 

Ports 1 to 16

Internal Gigabit Ethernet 1000BASE-X downlink ports that connect to the

 

blade enclosure.

 

 

Ports 17 to 18

Internal cross-connection ports that you can use to connect to a second

 

switch in the blade enclosure through a backplane connector. You can

 

configure these ports by using the Cisco IOS CLI. However, if the blade

 

switches are stacked, these ports are disabled.

 

 

Ports 19 to 22

10-Gigabit Ethernet module slots for use with the Cisco TwinGig Converter

 

Modules and Cisco X2 transceiver modules.

 

 

Ports 23 to 26

External 10/100/1000BASE-T copper Gigabit Ethernet uplink ports that

 

support auto-MDIX and autonegotiation.

 

 

Internal 100BASE-T

The Ethernet management port (Fa0) is used only for switch module

Ethernet port

management traffic, not for data traffic. It is connected to the

 

Onboard Administrator through the blade enclosure backplane connector.

 

Traffic to and from this port is isolated from the switch ports. This port

 

only supports autonegotiation with 100 Mb/s and full-duplex mode.

 

 

StackWise Plus ports

Stacking cable ports.

 

 

Console port

Switch module management port (RJ-45 connector).

 

 

Cisco Catalyst Blade Switch 3020 for HP

The Cisco Catalyst Blade Switch 3020 for HP is a 24-Gigabit Ethernet port, Layer 2+ switch module. Sixteen of the Gigabit Ethernet ports are internal 1000BASE-X downlink ports that connect to the blade enclosure. The other eight Gigabit Ethernet ports are external uplink ports that provide connections to other switches or routers. Uplink ports operate at 10/100/1000 M/ps if used as copper-based ports and operate at 1000 M/ps if small form-factor pluggable (SFP) fiber-optic modules are installed. See Table 2 for more detailed descriptions of the switch module ports.
