2 220T and 210T Overview Features This guide covers both the 12- and 24-port versions of the Intel ® Express 220T Stackable Hub and the Express 210T Stackable Hub (formerly known as the Express 10/100 Stackable Hub). Input 100-120VAC/2.5A 200-240VAC/1.

4 Understanding 220T Hubs 220T Port LEDs The LEDs above each port provide information about the port’ s configuration and status. LED Status Meaning Left Solid orange Device linked at 10Mbps. Solid green Device linked at 100Mbps. Blinking orange Receive activity at 10Mbps.
5 220T Hub LEDs The hub LEDs on the 220T indicate these conditions: collisions, status of internal bridging, if the hub is managed, and the condition of the hub’ s power supply .
6 Understanding 210T Hubs 210T Port LEDs The LEDs above each port provide information about the port’ s configuration and status. LED Status Meaning Left Solid green Port has a link. Blinking green Receive activity at port. Off No link detected. Right Solid yellow Port disabled by management (not applicable without optional Management Module).
7 210T Hub LEDs The 210T hub LEDs indicate these conditions: hub speed, collisions in the hub or stack of hubs, and whether the hub is managed. 10Base-T 100Base-TX Power Intel Express 210T Stackable Hub Collision Managed Status Change Hub Speed LED Status Meaning 10Base-T On Hub is operating at 10Mbps.
8 Connection Guidelines General • Ports on the 220T and 210T hubs are half-duplex. T o connect to a device at full-duplex, you must use the optional Ethernet or Fiber Modules. • 220T ports are autonegotiating and can operate at 10Mbps or 100Mbps. The hub matches the highest possible speed of an attached device.
9 Stacking Hubs Why Stack? The Express 220T and 210T hubs use the same connectors so they can be stacked together or stacked in combination with the Express 10/100 Stackable hub. By stacking Intel hubs you can: • increase the number of available ports, yet still treat the stack as a single repeater .
10 Bridging Segments Bridging 220T Hubs A bridge allows two segments to communicate with each other . T ypically , a bridge connects segments operating at different speeds, but it can also connect segments operating at the same speed.
11 Bridging 210T Hubs All ports on the Express 210T hub operate at the same speed (10Mbps or 100Mbps) so the hub belongs to only one segment at a time. The 210T hub doesn’t contain an internal bridge. T o communicate, the segments must be bridged by a 220T hub or by an external device (like a 10/100 switch).
12 Cabling Devices Media Requirements Incorrect cabling is often the cause of network configuration problems. Read the next two pages if you’re unsure of your requirements. 100Base-TX The 100Base-TX Fast Ethernet specification requires that you use CA T 5 UTP cabling to operate at 100Mbps.

14 Can I stack Intel Express 220T Stackable Hubs with Intel Express 210T Stackable Hubs or Intel Express 10/100 Stackable Hubs? Y es. These hubs use the same Intel Cascade Cable and connectors. Can I stack Intel Express 220T or 210T Stackable Hubs with Intel Express 100Base-TX Stackable Hubs? No.
15 Can I daisy-chain a 100Mbps hub to the 220T hub with UTP cabling? No. Only hubs operating at 10Mbps can be daisy-chained to the 220T . Y ou must use an Intel Cascade Cable to connect Intel hubs operating at 100Mbps. Can I daisy-chain 210T hubs together with UTP cabling? Only if the hubs are operating at 10Mbps.

Ein wichtiger Punkt beim Kauf des Geräts Intel 220T (oder sogar vor seinem Kauf) ist das durchlesen seiner Bedienungsanleitung. Dies sollten wir wegen ein paar einfacher Gründe machen:
Wenn Sie Intel 220T noch nicht gekauft haben, ist jetzt ein guter Moment, um sich mit den grundliegenden Daten des Produkts bekannt zu machen. Schauen Sie zuerst die ersten Seiten der Anleitung durch, die Sie oben finden. Dort finden Sie die wichtigsten technischen Daten für Intel 220T - auf diese Weise prüfen Sie, ob das Gerät Ihren Wünschen entspricht. Wenn Sie tiefer in die Benutzeranleitung von Intel 220T reinschauen, lernen Sie alle zugänglichen Produktfunktionen kennen, sowie erhalten Informationen über die Nutzung. Die Informationen, die Sie über Intel 220T erhalten, werden Ihnen bestimmt bei der Kaufentscheidung helfen.
Wenn Sie aber schon Intel 220T besitzen, und noch keine Gelegenheit dazu hatten, die Bedienungsanleitung zu lesen, sollten Sie es aufgrund der oben beschriebenen Gründe machen. Sie erfahren dann, ob Sie die zugänglichen Funktionen richtig genutzt haben, aber auch, ob Sie keine Fehler begangen haben, die den Nutzungszeitraum von Intel 220T verkürzen könnten.
Jedoch ist die eine der wichtigsten Rollen, die eine Bedienungsanleitung für den Nutzer spielt, die Hilfe bei der Lösung von Problemen mit Intel 220T. Sie finden dort fast immer Troubleshooting, also die am häufigsten auftauchenden Störungen und Mängel bei Intel 220T gemeinsam mit Hinweisen bezüglich der Arten ihrer Lösung. Sogar wenn es Ihnen nicht gelingen sollte das Problem alleine zu bewältigen, die Anleitung zeigt Ihnen die weitere Vorgehensweise – den Kontakt zur Kundenberatung oder dem naheliegenden Service.
