Power over Ethernet

Cisco Catalyst 9400 Series switches offer line cards, power supplies, and accessories required to deploy and operate standards-based Power over Ethernet, Power over Ethernet Plus (PoE/PoE+) and Cisco UPOE. PoE provides power over 100 m of standard Unshielded Twisted-Pair (UTP) cables when an IEEE 802.3af/at-compliant or Cisco pre-standard powered device is attached to the PoE/PoE+ and Cisco UPOE line card port. Instead of requiring wall power, attached devices such as IP phones, wireless base stations, video cameras, and other IEEE- compliant appliances can use power provided from the Cisco Catalyst 9400 Series UPOE line cards. This capability gives network administrators centralized control over power and eliminates the need to install outlets in ceilings and other out-of-the-way places where a powered device can be installed.

Although all references to ―PoE/PoE+/UPOE, ‖ ―inline power, ‖ and ―voice‖ power supplies and line cards are synonymous, there are currently four versions: Cisco pre-standard, IEEE 802.3af compliant, IEEE 802.3at compliant, and Cisco UPOE. Every Cisco Catalyst 9400 Series switch chassis and PoE power supply supports the IEEE 802.3af/at standard and the Cisco pre-standard power implementation, helping ensure backward compatibility with existing devices powered by Cisco. All IEEE 802.3af/at-compliant and Cisco UPOE line cards can distinguish an IEEE or Cisco pre-standard powered device from an unpowered Network Interface Card (NIC), helping ensure that power is applied only when an appropriate device is connected.

Energy Efficient Ethernet

Energy Efficient Ethernet (EEE) is an IEEE 802.3az standard that is designed to reduce power consumption in Ethernet networks during idle periods.

EEE can be enabled on devices that support Low Power Idle (LPI) mode. Such devices can save power by entering LPI mode during periods of low utilization. In LPI mode, systems on both ends of the link can save power by shutting down certain services. EEE provides the protocol needed to transition into and out of LPI mode in a way that is transparent to upper layer protocols and applications.

Features and benefits

Functional transparency

Cisco Catalyst 9400 Series switches offer a line of modules that support numerous speeds and physical media combinations. These line cards are functionally transparent; all the packet processing, queuing, buffering and Quality of Service (QoS) occur in the supervisor engine. To that end line cards acquire the features and capabilities of the installed supervisor engine. The architecture let you easily upgrade all Ethernet line cards on your Cisco Catalyst 9400 Series switches to newer switching functions by adding a new supervisor engine. The simple design of the line cards results in a very high Mean Time Between Failures (MTBF), helping ensure high availability for a single connection to an end user.

Modular versatility

Cisco Catalyst 9400 Series switches are a centralized architecture that is designed to provide dedicated wire- speed bandwidth to each line card slot within the chassis. Each line card has a dedicated bandwidth to the supervisor engine for packet processing. All network data that flows into Cisco Catalyst 9400 Series switches through the various line cards goes through the supervisor engine for processing, even in single-slot port-to-port communications.

A modular, centralized design allows you to use your investment in high-performance line cards across the entire line of Cisco Catalyst 9400 Series switch chassis and supervisor engines. With the centralized architecture of Cisco Catalyst 9400 Series switches, all line cards deployed in a chassis benefit from the enhanced features that the supervisor engine provides, including QoS; Layer 2, 3, and 4 routing; and hardware-based IPv6.

Optics

Cisco Catalyst 9400 Series switch line cards provide a variety of optical port types and port speeds, including SFP + and SFP.
