Connecting Devices To The Ethernet Ports - Cisco IE 4010 Hardware Installation Manual

Switch Installation

Connecting Devices to the Ethernet Ports

3. Pull the cover open, and pull the cover tab from the hinge.
4. Gently push the flash memory card to eject it. Place it in an anti-static bag to protect it from static discharge.
5. Push the replacement card into the slot, and press it firmly in place. The card is keyed so that you cannot insert it
the wrong way.
6. Place the flash card slot cover tabs into the hinge.
7. Close the cover, and 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, or Category 6 UTP cable. The
10BASE-T traffic uses Category 3 or Category 4 cable.
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.
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 a Ethernet
port, regardless of the type of connected device.
See the switch software configuration guide or the switch command reference on Cisco.com for more information about
autonegotiation and auto-MDIX.
If auto-MDIX is disabled, use the guidelines in
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, page
See Cable and Connectors, page 53
The ports provide PoE/PoE+ support for devices compliant with IEEE 802.3af/at and also provide Cisco prestandard
PoE/PoE+ support for Cisco IP Phones and Cisco Aironet Access Points.
On a per-port basis, you can control whether or not a port automatically provides power to a connected IP phone or an
access point.
To access an advanced PoE planning tool, use the Cisco Power Calculator on Cisco.com:
http://tools.cisco.com/cpc/launch.jsp
You can use this application to calculate the power supply requirements for a specific PoE/PoE+ configuration. The
results show output current, output power, and heat dissipation.
Warning: Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections
are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection
methods, unless the exposed metal parts are located within a restricted access location and users and service
people who are authorized within the restricted access location are made aware of the hazard. A restricted access
area can be accessed only through the use of a special tool, lock and key or other means of security. Statement
