SFP Installation

This section presents procedures to install and remove fiber-optic and 1000BASE-T SFP transceiver modules.

SFP modules are inserted into SFP module slots on the front of the switch.

You can use any combination of rugged SFP modules. Each SFP module must be of the same type as the SFP module on the other end of the cable, and the cable must not exceed the stipulated cable length for reliable communications.

SFP Installation Considerations and Guidelines

Observe the following guidelines when installing SFP modules in the switch.

General Guidelines

Removing and installing an SFP module can shorten its useful life. Do not remove and insert any module more often than absolutely necessary.


Caution

To prevent electrostatic-discharge (ESD) damage, follow standard board and component handling procedures.

Attention :

Pour éviter les dommages causés par les décharges électrostatiques (ESD), suivez les procédures standard de manipulation de la carte et des composants.


Caution

Do not install or remove the SFP module with fiber-optic cables attached. Doing so could result in damage to the cables, the cable connector, or the optical interfaces in the SFP module. Disconnect all cables before removing or installing an SFP module.

Attention :

Ne pas installer ni retirer le module SFP lorsque des câbles à fibre optique sont branchés. Cela pourrait endommager les câbles, le connecteur de câble ou les interfaces optiques du module SFP. Avant le retrait ou l’installation d’un module SFP, déconnectez tous les câbles.

Power Guidelines


Caution

The uplink SFP and SFP+ ports support up to 4 W of total SFP power. Most SFP modules draw 1 W or less and allow use of all four SFP uplinks. When installing higher power modules, ensure that the total rated power draw remains below 4 W. When installing modules that draw higher than 1 W, leave at least one empty slot between them.

Attention :

Les ports de liaison ascendante SFP et SFP+ prennent en charge jusqu’à 4 W d’alimentation SFP totale. La plupart des modules SFP consomment 1 W ou moins et permettent l’utilisation des quatre liaisons ascendantes SFP. Lors de l’installation de modules d’alimentation de plus grande puissance, assurez-vous que la puissance nominale totale reste inférieure à 4 W. Lors de l’installation de modules dont la consommation est supérieure à 1 W, laissez au moins un logement vide entre eux.

Temperature Considerations

Some SFP modules are not rated to work at very low temperatures.


Caution

Depending on the SFP module you use, the operating temperature limits may be affected. Choose an SFP module appropriate to the installed environment. For a complete list of supported SFP modules, see the Cisco Catalyst IE9300 Rugged Series Data Sheet on Cisco.com.

Attention :

Selon le module SFP utilisé, les limites de température de fonctionnement peuvent être affectées. Sélectionnez un module SFP approprié à l’environnement où il est installé. Pour obtenir une liste complète des modules SFP pris en charge, consultez la fiche technique des commutateurs robustes de la gamme Cisco Catalyst IE9300 sur Cisco.com.

Place the flash card slot cover tabs into the hinge.

Step 7

Close the cover, and then hand-tighten the screw.

Connecting Devices to the Ethernet Ports

The Ethernet ports use standard RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires Category 5, Category 5e, Category 6 UTP, or later cable. The 10BASE-T traffic uses Category 3 or Category 4 cable.


Note

Use shielded Ethernet cables to improve EMI/EMC performance.

The autonegotiation feature is enabled by default on the switch. At this setting, the switch ports configure themselves to operate at the speed of the attached device. If the device does not support autonegotiation, you can set the switch port speed and duplex parameters. To maximize performance, either let the ports autonegotiate both speed and duplex, or set the port speed and duplex parameters on both ends of the connection.

See the switch software configuration guide or the switch command reference on Cisco.com for more information about autonegotiation and auto-MDIX.

For simplified cabling, the automatic medium-dependent interface crossover (auto-MDIX) feature is enabled by default. With auto-MDIX enabled, the switch detects the required cable type for copper Ethernet connections and configures the interface accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to an Ethernet port, regardless of the type of connected device.

If auto-MDIX is disabled, use the guidelines in Cables and Adapters to select the cable for connecting the Ethernet ports to other devices.

When using PoE/PoE+, those ports have the same autonegotiation settings and cabling requirements as those in the Connecting Devices to the Ethernet Ports. These ports provide PoE power.

See the section Cable and Connectors for information on the cables and connectors.

The ports provide PoE/PoE+ support for devices compliant with IEEE 802.3af/at.

On a per-port basis, you can control whether or not a port automatically provides power to a connected PoE powered device (PD).


Caution

Category 5e and Category 6 cables can store high levels of static electricity. Always ground the cables to a suitable and safe earth ground before connecting them to the switch or other devices.

Attention :

Les câbles de catégories 5e et 6 peuvent contenir des niveaux élevés d’électricité statique. Procédez à une mise à la terre adaptée et sûre avant de les connecter au commutateur ou aux autres appareils.
