Cisco Systems warranty Cisco Catalyst Blade Switch 3020 for HP Port Descriptions

The blade server includes a chassis management module, the Onboard Administrator. Each switch module connects internally to the Onboard Administrator through 100BASE-T Ethernet links. You can manage the switch modules through the Onboard Administrator on a management network that is isolated from other switch traffic. You can also manage the switch module through any of the external uplink ports.

Table 1 describes the switch module ports. Each external port has an associated LED.

Table 1	Cisco Catalyst Blade Switch 3020 for HP Port Descriptions
Port		Description
Ports 1 to 16		Internal Gigabit Ethernet 1000BASE-X downlink ports.
Ports 17 to 20 and		Dual-purpose SFP module/RJ-45 copper Ethernet uplink ports. The SFP
Ports 17x to 20x		module ports support only Cisco 1000BASE-SX fiber-optic modules.
		By default, the switch module dynamically selects the interface type that first
		links up. SFP modules have precedence if both SFP module and copper Ethernet
		interface types are in link-up state. You can also specifically configure each port
		for either copper Ethernet or SFP modules if you do not want to use
		autodetection.
		The copper Ethernet ports support automatic medium-dependent interface
		crossover (auto-MDIX) and autonegotiation.
		For information about configuring speed and duplex settings for a
		dual-purpose uplink port, see the switch module software configuration guide.
Ports 21x to 22x		External 10/100/1000BASE-T copper Gigabit Ethernet uplink ports that
		support auto-MDIX, and autonegotiation.
Ports 23x to 24x		Dual-purpose external/internal 10/100/1000BASE-T copper Gigabit Ethernet
		uplink ports. These ports can be configured for internal 1000BASE-X
		cross-connection with a corresponding switch module. When ports 23x and
		24x are in external operation mode, they support auto-MDIX and
		autonegotiation. The default is external operation mode.
Internal		This port (fa0) is used only for switch module management traffic, not for data
100BASE-T		traffic. It is connected to the Onboard Administrator through the blade server
Ethernet port		backplane connector.
Console port		RJ-45 switch module management port.

The switch module is powered from the blade server backplane, and temperature management is provided by the blade server. There is no fan on the switch module.
