Connecting Devices

RJ-45 Switch Ports

RJ-45 connectors are located on the front panel of the switch.


All ports can negotiate full-and half-duplex modes automatically. These switching ports allow users to connect the switches to 10Base-T and 100Base-T on
ports 1-16 (2216), ports 1-24 (2224, 2324) and 1000Base-T devices on uplink ports 25 and 26 on the 2324.

Connecting Two or More Switches Together

Each port supports Auto MDI and MDIX functionality. When cascading with other switches or hubs, each port can connect directly to a switch or hub with
straight-through twisted-pair cable (see Figure1-4).

Figure 1-4. Cascading Switches
NOTE: Ensure that Category 5E (CAT 5E) cabling is used for connecting devices at 1000-Mbps Gigabit Ethernet speed.
NOTE: Do not connect two switches together with more than one cable. Using multiple cables to connect switches can create a loop and cause
collisions.



Connecting Switches to Other Devices

By connecting a switch to other devices, you can form a small network. All the RJ-45 ports support Auto MDI/MDIX and therefore automatically detect the type
of cable used to connect the network device. Crossover or straight-through networking cables can be used to connect PCs as well as other networking
devices like hubs or routers to the switch. All ports on the switch automatically negotiate speed and whether to operate in full duplex or half duplex.

Typical Deployments

Your switch can be deployed in small and large workgroups. Figure1-5 depicts a typical small workgroup network that has a limited number of attached
devices. Figure1-6 Figure 1.6 depicts a typical large workgroup that has several groups of individuals not all working in the same physical area.

Figure 1-6. Large Workgroup

Class-of-Service

The switch supports tag-based prioritization following the IEEE 802.1p standard. The eight levels of IEEE 802.1p priority are mapped to the two priority
queues of each port. For each port, the two priority queues are scheduled following a Weighted Round Robin scheme.


Table 1-1. Tag-Based Prioritization


Mounting Kit Instructions

The switches come with mounting brackets and screws for rackmounting or wallmounting and rubber feet for stationing on a flat surface.

Installing the Switch on a Flat Surface

The switch can be installed on any appropriate level surface that can safely support the weight of the switches and their attached cables. There must be
adequate space around the switch for ventilation and access to cable connectors.

To install the switch on a flat surface, complete the following steps:
1. Set the switch on the flat surface and check for proper ventilation.

Allow at least 5.1 cm (2 inches) on each side for proper ventilation and 12.7 cm (5 inches) at the back for power cable clearance.
2. Attachrubberfeetoneachmarkedlocationonthebottomofthechassis.

The rubber feet are optional, but are recommended to keep the switch from slipping.

Installing the Switch in a Rack

TheswitchcanbeinstalledinDellPowerEdge™racks,whichare48.3cm(19inches).Itcanalsobeinstalledinmostotherstandard19-inch racks and most
telco two-post racks.


To install the switch in a rack, complete the following steps:
1. Use the supplied screws to attach a mounting bracket to each side of the switch (see Figure1-7).

NOTE: The IEEE 802.1p priority information is part of the IEEE 802.1q tag that also defines VLAN memberships. The switches will ignore the VLAN
membership information in the tag (that is, all ports are part of all VLANs), but will preserve the full tag information—including packet priority and
VLANID—when transmitting the packet at the destination port.
NOTE: Do not install rubber feet on the switch if you are rackmounting the switch.

2. Install the cage nuts onto the mounting rails of your rack, if your rack requires them.

3. Position the switch in the rack and align the holes in the mounting bracket with the holes in the rack.
4. Insert and tighten two screws appropriate for your rack through each of the mounting brackets.

Installing the Switch on a Wall

To mount the switch on a wall, complete the following steps:
1. Ensure that the mounting point meets the following requirements:
lThe wall surface must be capable of supporting the switch.
lAllow at least 5.1 cm (2 inches) on each side for proper ventilation and 12.7 cm (5 inches) at the back for power cable clearance.
lThe location must not be located in direct sunlight.
lThe location must not be within 2 feet of any heating vents, nor should any area heating vent point toward the unit.
lThe location must be ventilated to prevent heat buildup.
lDo not locate the switch where there may be data or electrical cabling located directly behind the unit.
lThe power cable must reach an outlet.
2. Use the supplied screws to attach a mounting bracket to each side of the switch (see Figure1-8).
Figure 1-8. Brackets for Wall Installation

3. Place the switch against the wall and mark the wall through the holes of the brackets.
4. Drill holes in the wall for the brackets and install the appropriate mounting hardware (not supplied).
5. Place the switch against the wall so that the bracket holes align with the holes in the wall.
6. Insert and tighten the screws through each of the mounting brackets.


Problem
Probable Cause
Corrective Action
Power LED is not lighted.
There is no power to the switch.
Confirm that the switch is connected to a properly functioning
and active power source.
Ensure that the power cable is securely connected to the
switch and to a power source.
Link LED is not lighted.
The cable is not securely connected to the switch or the
attached device.
Ensure that the connectors are fully inserted into the ports of
the switch and the attached device.
The attached device is not configured correctly, or it is not
powered on.
Ensure that the attached device is powered on. Verify that the
NIC on the attached device is operating properly.
The cable is damaged or not properly terminated.
Test the cable.

Try a known working cable.
Ensure that the cables are terminated using TIA 568A or 568B
standards.

The cable's maximum distance has been exceeded.
10Base-T, 100Base-T, and 1000Base-T cables have limitations
for link lengths. Move the connected device closer to the switch
and use a shorter cable.
Mismatched duplex mode.
Ensure that all devices connected to the switch are configured
to automatically detect and set port speed and duplex settings.
Bad switch port.
Reconnect the connector for the affected link to a different
switch port.
Link speed LED indicates a
lower speed than expected.
Incorrect cable grade.
Ensure that you are using Category 5 cable or better for all
10Base-T and 100Base-T links, or Category 5e for 1000Base-T
links.
Damaged cable.
Test any cables that have kinks, sharp bends, or appear to be
damaged.
The cable's maximum distance has been exceeded.
10Base-T, 100Base-T, and 1000Base-T cables have limitations
for link lengths. Move the connected device closer to the switch
and use a shorter cable.
Link LED is lighted, but the
activity (ACT) LED does not
blink.
There is no Ethernet traffic on the link. The LED blinks only
when traffic is being passed to or sent from a device that is
connected to the port.
No action required.
The attached device is not configured correctly.
Verify that the port or NIC on the attached device is operating
properly.
Link LED is lighted and the
FDX/HDX LED blinks
occasionally.
This can be normal link activity. Some collisions take place
during normal operation.
No action required.
Link LED is lighted and the
FDX/HDX LED blinks
frequently.
Mismatched duplex mode.
Ensure that any devices connected to the switch are set to
automatically detect and set port speed and duplex settings.
The link is reaching its maximum capacity.
Resegment the network to decrease the number of users on
the link.
