Chapter 1: Introduction
1.1 Overview
AG6248C PoE has 48 10/100/1000BaseT copper ports plus 2 combo SFP ports and 2 SFP+
ports. Each copper port supports auto-sensing and auto negotiation. To further simplify
network setups, all ports also automatically sense half- or full-duplex connections for high-
speed server or switch-to-switch congurations. The AG6248C PoE provides power and data
from a single point, using Power over Ethernet (PoE) over a single Cat-5 cable. All of these
48 10/100/1000Base-T ports can supply industry-standard IEEE 802.3at power over Ethernet.

2.5 Power Supply Modules
The power supply modules are hot-swappable power supply units (PSUs) for the switch.
You can install up to two PSUs. The PSUs operate in a load-sharing mode and provides 1+1
redundancy.
(Figure 2-7: Power Supply Unit)
NOTE:
1+1 redundancy is a system where a switch power supply is backed up by
another switch power supply in a load-sharing mode. If one power supply fails,
the other power supply takes over the full load of the switch.
WARNING:
• The switch includes plug-in power supply and fan tray modules that are
installed into its chassis. All modules must have a front-to-back airow
direction, or back-to-front airow direction.
• Risk of explosion if battery is replaced by an incorrect type. Dispose of used
batteries according to the instructions.
• Remove the power cable from the module prior to removing the module
itself. Power cable must not be connected prior to insertion in the chassis or
equivalent.
2.6 Fan Tray Module
The fan tray module is part of the switch air cooling system that provides cooling for the
switch. You must install the fan tray module in the switch that matches the airow direction
of the installed power supply unit.
(Figure 2-8: Fan Tray Module)

11
AG6248C Power-Over-Ethernet Switch
CAUTION:
Due to the switch’s weight, it should be installed by at least two people.
(Figure 3-2: Installing the Switch in a Rack)
3. If installing a single switch only, go to “Connecting to a Power Source”.
4. If installing multiple switches, mount them in the rack, one below the other, in any order.
3.1.2 Horizontal Surface Mounting
The switch includes four pre-installed rubber feet for horizontal surface mounting.
To mount devices on a horizontal surface, follow these steps:
1. Attach the four adhesive feet to the bottom of the rst switch.
(Figure 3-3: Attaching the Adhesive Feet)
2. Set the device on a at horizontal surface near an AC power source, making sure there are
at least two inches of space on all sides for proper air ow.
3. If installing a single switch only, go to “Connecting to a Power Source”.
4. If installing multiple switches, attach four adhesive feet to each one, then place each device
squarely on top of the one below, in any order.

12
• InstallationChapter 3
3.2 Installing an Optional SFP+ Transceiver
The SFP+ ports support the following optional SFP+ transceivers:
•10GBASE-CR
•10GBASE-SR
•1000BASE-SX
•1000BASE-LX
(Figure 3-4: Inserting an SFP+ Transceiver into a Port)
To install an SFP+ transceiver, follow these steps:
1. Consider network and cabling requirements to select an appropriate SFP+ transceiver
type.
2. Insert the transceiver with the optical connector facing outward and the port connector
facing down. Note that SFP+ transceivers are keyed so they can only be installed in one
orientation.
3. Slide the SFP+ transceiver into the port until it clicks into place.
NOTE:
•SFP+ transceivers are hot-swappable. The switch does not need to be
powered off before installing or removing a transceiver. However, always
rst disconnect the network cable before removing a transceiver.
•SFP+ transceivers are not provided in the switch package.

13
AG6248C Power-Over-Ethernet Switch
3.3 Connecting to the Console Port
This port is used to connect a console device to the switch through a nullmodem serial cable.
The console device can be a PC or workstation running a VT-100 terminal emulator, or a
VT-100 terminal. An RJ-45-to-DB-9 cable is supplied with the switch for connecting to a PC’s
RS-232 serial DB-9 DTE port. The pin assignments used in the RJ-45-to-DB-9 cable are
described below.
DP-9 port
RJ-45 connector
(Figure 3-5: Console Port Connection)
3.4 Connecting to a Power Source
To connect a switch to a power source:
1. Insert the power cable plug directly into the AC socket of a PSU located at the back of the
switch.
Power socket
(Figure 3-6: Power Socket)
2. Plug the other end of the cable into a grounded, 3-pin, AC power source.
NOTE:
For International use, you may need to change the AC line cord. You must use a
line cord set that has been approved for the socket type in your country.

14
• InstallationChapter 3
3. Check the PSU and front-panel LEDs as the device is powered on to be sure that AC
power is being received and the PWR LED is on. If not, check that the power cable is
correctly plugged in.
4. Repeat steps 1 and 2 when a second PSU module is installed.
Two installed PSU modules operate in a load-sharing mode and provide 1+1 redundancy.

15
AG6248C Power-Over-Ethernet Switch
Chapter 4: Making the Network Connections
The AG6248C PoE switch is designed to provide Ethernet connections between server racks
through its 1G BASE-T or 10G SFP+ ports. This chapter describes how to make network
connections to the switch.
4.1 Twisted-pair Connections
The switch’s Management port connection requires an unshielded twisted-pair (UTP)
cable with RJ-45 connectors at both ends. Use Category 5, 5e or 6 cable for 1000BASE-T
connections, Category 5 or better for 100BASE-TX connections, and Category 3 or better for
10BASE-T connections.
4.1.1 Cabling Guidelines
The RJ-45 port on the switch supports an automatic MDI/MDI-X pinout conguration, so
you can use a standard straight-through twisted-pair cable to connect to any other network
device (PCs, servers, switches, routers, or hubs).
4.1.2 Connecting to the Management Port
1. Attach one end of a twisted-pair cable segment to the link device’s RJ-45 connector.
RJ-45 connector
(Figure 4-1: Making a Connection to the Management Port)
2. Attach the other end to the Management port on the switch.
Make sure the twisted pair cable does not exceed 100 meters (328 ft) in length.
3. When the connection is made, the Mgmt LED (on the switch) will light green to indicate that
the connection is valid.

16
• Making the Network ConnectionsChapter 4
4.2 Fiber Optic Connections
Optional 1G SFP or 10G SFP+ transceivers can be used for ber connections from the
switch to other network devices in the data center. A 1G SFP or 10G SFP+ transceiver may
also be used for long distance connections to devices at another site.
WARNING:
•This switch uses lasers to transmit signals over ber 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.
•When selecting a ber SFP/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/SFP+ transceiver.
The following gure illustrates the SFP/SFP+ port ber connection.
(Figure 4-2: Making SFP/SFP+ Port Fiber Connection)
4.3 Ethernet Cabling
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 3 or better for 10BASE-T, Category 5 or better for 100BASE-TX,
and Category 5, 5e or 6 for 1000BASE-T.
•Protection from radio frequency interference emissions
•Electrical surge suppression
•Separation of electrical wires (switch related or other) and electromagnetic elds from
data based network wiring
•Safe connections with no damaged cables, connectors or shields
