Product Information

Removing and installing an SFP module can shorten its useful life. Do not remove and insert any module more often than is be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. models, the power range is between 195W to 370W. For the 48-port switch models, the power range is between 180W and 740W. Allow at least 1.75 in. (4 cm) of clearance from the top cover, if you are installing the switch in upright position. the default-interface command on the mapped ports. For more information about the command, refer to the Software Configuration Guide.

Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures. Make sure or Category 5e twisted pair (UTP) cable. The 10BASE-T traffic can use Category 3 or Category 4 UTP cable. or 4 fixed 1 Gigabit Ethernet Small Form-Factor Pluggable (SFP)/RJ 45 Combo uplinks (8 Port models only) or 4 fixed 10 Gigabit Ethernet Enhanced SFP (SFP+) uplinks on the Gigabit Ethernet models and 4 fixed 1 Gigabit Ethernet Small Form-Factor Pluggable (SFP) and 2 RJ 45 Combo uplinks on the Fast Ethernet models Physically, there is no amber LED on the device. For all LED-related information of the device, run the show hardware led command in privileged EXEC mode.Spanning Tree Root Guard (STRG) to prevent edge devices that are not in the network administrator’s control from becoming Spanning Tree Protocol (STP) root nodes. Comprehensive 802.1X features to control access to the network, including flexible authentication, 802.1X monitor mode, and RADIUS change of authorization. With autonegotiation, the switch port configurations change to operate at the speed of the attached device. If the attached Fast Ethernet ports; 2 1-Gigabit SFP module uplink slots or 2 RJ-45 slots combo ports; 2 1-Gigabit Ethernet SFP

Technology Rooms in accordance with Article 645 of the National ElectricalCode and NFPA 75. Statement 0444 This section describes the front panel components of Cisco Catalyst 1000 24-port and 48-port Fast Ethernet switches. Cisco Catalyst 1000 Series Switches offer intelligent traffic management that keeps everything flowing smoothly. Flexible mechanisms for marking, classifying, and scheduling deliver superior performance for data, voice, and video traffic, all at wire speed. Primary QoS features include: device does not support autonegotiation, you can manually set the switch interface speed and duplex parameters.Align the module in front of the slot opening, and push until you feel the connector snap into place. This policy supersedes any previous warranty or software statement and is subject to change without notice. Position the switch directly in front of the DIN rail, making sure that the top of the DIN rail mount clip hooks over the IEEE 802.1AX,IEEE 802.1D,IEEE 802.1Q,IEEE 802.1ab,IEEE 802.1p,IEEE 802.1s,IEEE 802.1w,IEEE 802.1x,IEEE 802.3,IEEE 802.3ab,IEEE 802.3ad,IEEE 802.3ae,IEEE 802.3af,IEEE 802.3ah,IEEE 802.3at,IEEE 802.3az,IEEE 802.3u,IEEE 802.3x,IEEE 802.3z

Category 5e and Category 6 cables can store high levels of static electricity. Always ground the cables to a suitable and front panel facing down or to the side to prevent airflow restriction and to provide easier access to the cables Customers are provided with maintenance updates and bug fixes designed to maintain the compliance of the software with published specifications, release notes, and industry standards as long as the original end user continues to own or use the product or up to one year from the end-of-sale date for this product, whichever occurs earlier. If the module has a bale-clasp latch, pull the bale out and down to eject the module. If the latch is obstructed and you cannot Network Time Protocol (NTP) provides an accurate and consistent timestamp to all intranet switches.

BPDU Guard to shut down Spanning Tree PortFast-enabled interfaces when BPDUs are received, to avoid accidental topology loops. IEEE 802.1X user distribution, which enables you to load-balance users with the same group name across multiple different VLANs.

the correct procedures could result in a hazardous situation to people and damage to the system. Statement 378 One of the remaining member switches becomes the new active switch. All the other member switches in the group remain as Do not remove the dust plugs from the modules or the rubber caps from the fiber-optic cable until you are ready to connectonly the software release that introduced support for a given feature in a given software release train.
