Cable Labeling and Connection Records

When planning a network installation, it is essential to label the opposing ends of
cables and to record where each cable is connected. Doing so will enable you to
easily locate inter-connected devices, isolate faults and change your topology
without need for unnecessary time consumption.

To best manage the physical implementations of your network, follow these
guidelines:

◆ Clearly label the opposing ends of each cable.

◆ Using your building’s floor plans, draw a map of the location of all network-

connected equipment. For each piece of equipment, identify the devices to
which it is connected.

◆ Note the length of each cable and the maximum cable length supported by the

switch ports.

◆ For ease of understanding, use a location-based key when assigning prefixes to

your cable labeling.

◆ Use sequential numbers for cables that originate from the same equipment.

◆ Differentiate between racks by naming accordingly.

◆ Label each separate piece of equipment.

– 30 –

◆ Display a copy of your equipment map, including meanings of all abbreviations

at each equipment rack.

Copper Cabling Guidelines

The RJ-45 ports on the switch support automatic MDI/MDI-X pinout configuration,
which enables you to use standard straight-through twisted-pair cables to connect
to any other network device (PCs, servers, switches, routers, or hubs).

The connection requires an unshielded twisted-pair (UTP) or shielded twisted-pair
(STP) cable with RJ-45 connectors at both ends.

To ensure proper operation when installing the switch into a network, make sure
that the current cables are suitable for 10BASE-T, 100BASE-TX, or 1000BASE-T
operation. Check the following criteria against the current installation of your
network:

◆ Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP) cables

with RJ-45 connectors; Category 5, 5e or better cable for 1000BASE-T
connections, Category 5 or better for 100BASE-TX connections, and Category 3
or better for 10BASE-T connections..

◆ Protection from radio frequency interference emissions

◆ Electrical surge suppression

◆ Separation of electrical wires (switch related or other) and electromagnetic

fields from data based network wiring

◆ Safe connections with no damaged cables, connectors or shields

Assignments

All 100BASE-TX RJ-45 ports support automatic MDI/MDI-X operation, so you can
use straight-through or crossover cables for all network connections to PCs,
switches, or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of the
cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the
cable.

1000BASE-T Cable Requirements

All Category 5 UTP cables that are used for 100BASE-TX connections should also
work for 1000BASE-T, providing that all four wire pairs are connected. However, it is
recommended that for all critical connections, or any new cable installations,
Category 5e (enhanced Category 5) or Category 6 cable should be used. The
Category 5e and 6 specifications include test parameters that are only
recommendations for Category 5. Therefore, the first step in preparing existing
Category 5 cabling for running 1000BASE-T is a simple test of the cable installation
to be sure that it complies with the IEEE 802.3-2008 standards.

Power-over-Ethernet Guidelines

The switch supports both IEEE 802.3af and IEEE 802.3at-2009 PoE standards that
enable DC power to be supplied from the switch’s RJ-45 copper ports to connected
devices by utilizing certain wire pairs in the connecting Ethernet cable.

The total PoE power delivered by all ports cannot exceed the 390 W switch power
budget. This means that up to 12 ports can supply a maximum 30 W of power
simultaneously to connected devices, or all 24 ports can supply a maximum of

15.4 W simultaneously. For each attached PoE-compliant device, the switch
automatically senses the load and dynamically supplies the required power.

Any PoE-compliant device attached to a port can directly draw power from the
switch over the Ethernet cable without requiring its own separate power source.
This capability gives network administrators centralized power control for devices

– 33 –

such as IP phones and wireless access points, which translates into greater network
availability.

Fiber Cabling Guidelines

The switch provides four slots for SFP-compliant fiber-optic transceivers.

Note that all 1000BASE fiber optic ports operate at 1 Gbps full duplex. The 100BASE
fiber optic ports operate at 100 Mbps full duplex.

the relevant standards specified in this section. However, power budget constraints
should also be considered when calculating the maximum fiber optic cable length
for a particular link.

Note:

Maximum distances may vary for different SFP vendors.

To ensure proper operation when installing the switch into a network, make sure
that the current fiber cables are suitable for 1000BASE or 100BASE operation. Check
the following criteria against the current installation of your network:

◆ Be sure to secure fiber cables properly and route them away from the switch.

– 34 –

◆ Do not exceed the minimum bending radius for fiber cables (typically a few

inches).

◆ Use cable ties to bundle fiber cables together and secure coiled loops of excess

cable.

◆ Do not let fiber cables hang free supporting their own weight.

◆ Do not let fiber cables pull in any way that puts stress on the connectors.

How to Connect to Twisted-Pair Copper Ports

Follow these steps to connect cables to 1000BASE-T RJ-45 twisted-pair copper
ports.

1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector.

Chapter 6

1000BASE-T RJ-45 Port Category 5,5e or 6 Cable

2. Attach the other end to an available port on the switch.

Make sure each twisted pair cable does not exceed 100 meters (328 ft) in
length.

3. As each connection is made, the Link LED (on the switch) corresponding to

each port will turn on green to indicate that the connection is valid.

Warning:

This switch uses lasers to transmit signals over fiber optic cable. The
lasers are compliant with the requirements of a Class 1 Laser Product and are
inherently eye safe in normal operation. However, you should never look directly at
a transmit port when it is powered on.

Warning:

When selecting a fiber SFP device, considering safety, please make sure

that it can function at a temperature that is not less than the recommended
maximum operational temperature of the product. You must also use an approved
Laser Class 1 SFP transceiver.

1. Remove and keep the fiber port’s rubber plug. When not connected to a fiber

cable, the rubber plug should be replaced to protect the optics.

2. Check that the fiber terminators are clean. You can clean the cable plugs by

wiping them gently with a clean tissue or cotton ball moistened with a little
ethanol. Dirty fiber terminators on fiber optic cables will impair the quality of the
light transmitted through the cable and lead to degraded performance on the
port.

3. Connect one end of the cable to the SFP port on the switch and the other end to

the SFP port on the other device. Since SFP connectors are keyed, the cable can
be attached in only one orientation.

4. As a connection is made, check the Link LED on the switch to be sure that the

connection is valid.

System Self-Diagnostic Test Failure

If the DIAG LED indicates a failure of the system power-on-self-test (POST), you can
use a console connection to view the POST results. The POST results may indicate a
failed component or help troubleshoot the problem. For more information on
connecting to the console port and using the CLI, refer to the Management Guide.

Note a POST failure normally indicates a serious hardware fault that cannot be
rectified or worked around. If you encounter a POST failure, you should contact
your dealer for assistance.

Power Problems

Installation

Chapter A

If a power indicator does not turn on when the power cord is plugged in, you may
have a problem with the power outlet, power cord, or internal power supply.
However, if the switch shuts down after operating for a continuous period, check
for loose power connections, power losses or surges at the power outlet. If you still
cannot isolate the problem, the internal power supply may be defective.

Verify that all system components have been properly installed. If one or more
components appear to be malfunctioning (such as the power cord or network
cabling), test them in an alternate environment where you are sure that all the
other components are validated to be functioning properly.

Power Problems

In-Band Access

You can access the management agent in the switch through a connection to any
port using Telnet, a web browser, or other network management software tools.
However, you must first configure the switch with a valid IP address, subnet mask,
and default gateway. If you have trouble establishing a link to the management
agent, check to see if you have a valid network connection. Then verify that you
entered the correct IP address. Also, be sure the switch port has not been disabled.
If it has not been disabled, then check the network cabling that connects your
remote location to the switch.
