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 have a front-to-back 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.

Chapter 4: Making the Network Connections
The AGC7648 switch is designed to provide high-speed, lossless Ethernet connections
between server racks through its 10G SFP+ or 100G QSFP28 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 10G SFP+ or 100G QSFP28 transceivers can be used for ber connections from
the switch to other network devices in the data center. An SFP+ or QSFP28 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+ or QSFP28 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+ or QSFP28 transceiver.
The following gure illustrates the SFP+ or QSFP28 port ber connection.
(Figure 4-2: Making SFP+ Port Fiber Connection)
(Figure 4-3: Making QSFP28 Port Fiber Connection)

AGC7648 Deep-Buffer Switch
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
