Cable Labeling and Connection Records

| Port Connections

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.

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

at each equipment rack.

Note:

SFP transceivers are hot-swappable. The switch does not need to be
powered off before installing or removing a transceiver.

Note:

SFP transceivers are not provided in the switch package.

To install an SFP transceiver, do the following:

1. Consider network and cabling requirements to select an appropriate

transceiver type that is also compatible with the switch transceiver support.

2. If the SFP slot is covered with a rubber protective cap, remove the cap and keep

it for later replacement.

3. Insert the transceiver with the optical connector facing outward and the slot

connector facing down. Note that SFP transceivers are keyed so they can only
be installed in the correct orientation.

4. Slide the transceiver into the slot until it clicks into place. If you do not

immediately connect a cable to the port, use a rubber protective cap to keep
the transceiver optics clean.

How to Connect to Twisted-Pair Copper Ports

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

10/100BASE-TX Pin

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 The ECS4210-12P switch supports both IEEE 802.3af and IEEE 802.3at-2009 PoE

standards that enable DC power to be supplied from eight of the switch’s RJ-45
copper ports (ports 1-8) to connected devices by utilizing certain pairs of the
connecting Ethernet cable.

The total PoE power delivered by all ports cannot exceed the 150 W power budget.
This means that up to 4 ports can supply a maximum 30 W of power simultaneously
to connected devices, or all 8 ports can supply up to 16.7 W simultaneously.

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

For each attached PoE-compliant device, the switch automatically senses the load
and dynamically supplies the required power. The switch delivers power to a device
using the wire pairs in UTP or STP cable.

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.

Connection Procedure Follow these steps to connect cables to SFP transceiver ports.

Warning:

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.

Note:

Be sure to secure cables properly and route them away from the switch
without exceeding the minimum bending radius for fiber cables (typically a few
inches). Use cable ties to bunder cables together and secure coiled loops of excess
cable. Do not let cables hang free supporting their own weight or pull in any way
that puts stress on the connectors.

Power and Cooling Problems

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.

Installation

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 functioning properly.

Chapter A

Power and Cooling Problems

| Troubleshooting

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.
