2 APC Ethernet Switches: Installation, Troubleshooting, Specifications
Installation
Desktop installation
Place the switch on a large, clean, level surface with a power outlet nearby. Make sure there is enough
clearance around the switch for attaching cables and the power cord, and for air circulation.
Attaching rubber feet.
1. Make sure the mounting surface on the bottom of the switch is free of grease and dust.
2. Remove the adhesive backing from the rubber feet.
3. Apply one rubber foot to each corner on the bottom of the switch to protect the switch from
shocks and vibrations.
Rack-mounted installation
The switch comes with a rack-mount kit and can be mounted in an EIA standard size, 19-inch rack.
The switch can be placed in a wiring closet with other equipment.
To mount the switch in a rack:
1. Position one bracket to align with the holes on one side of the switch and secure it with the
smaller bracket screws. Attach the remaining bracket to the other side of the switch.
APC Ethernet Switches: Installation, Troubleshooting, Specifications 3
Introduction: Installation
2. Position the switch in the rack by aligning the holes in the brackets with the appropriate holes
on the rack. Secure the switch to the rack with the rack-mounting screws.
Applying power
Connect the cord of the power adapter to the power socket on the rear panel of the switch. Connect
the other end of the power cord to an APC UPS that is connected to a power outlet. Check the power
indicator on the front panel to make sure that the switch is receiving power.
After you connect the power cord of an AP9224112, use the power switch on the rear
panel to supply power to the unit.
Note
Connecting the switch
The RJ-45 ports use either unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable.
• For 10 Mbps connections use 100Ω Category 3, 4, or 5 cable
• For 100 Mbps connections use 100Ω Category 5 cable
• For 1000 Mbps connections use 4-pair Category 5 copper cabling
The length of any twisted-pair connection must not exceed 328 feet (100 meters).
Note

Installing a mini-GBIC (SFP) transceiver
To install a mini-GBIC (SFP) transceiver:
1. Insert the transceiver into the mini-GBIC port with the exposed section of PCB board facing
down.
2. Push the transceiver firmly until it clicks into place.
3. The switch automatically detects the installed transceiver. Check the LEDs to verify that it is
functioning properly.
Removing a mini-GBIC (SFP) transceiver
To remove a mini-GBIC (SFP) transceiver from the mini-GBIC port:
1. Remove the fiber-optic cables from the transceiver.
2. Unlock the transceiver’s latch (latch styles vary).
Introduction: Installation
3. Pull the transceiver out of the mini-GBIC port.
4. Put the dust cover on the transceiver.

When you install the mini-GBIC (SFP) transceiver into the port on the switch, you must
disconnect any device connected to its partner gigabit copper port of the same number. If
the gigabit copper port is occupied, the switch will not detect the mini-GBIC (SFP) that
you installed.

Troubleshooting
How to Resolve Problems
This chapter describes common problems that may occur when using the switch and their possible
solutions.
First, use the information in this chapter to attempt to resolve a problem. If you cannot resolve the
problem, contact APC Worldwide Customer Support using the numbers listed on the back cover of
this guide.
14 APC Ethernet Switches: Installation, Troubleshooting, Specifications
Specific Problems and Their Solutions
Diagnosing LED Indicator
If the LNK LED does not illuminate after connection, check the following:
• Verify that the switch and any devices attached to it are turned on.
• Be sure the connecting cable is plugged into both the switch and its corresponding device.
• Verify that the proper cable type is used and its length does not exceed specified limits.
See “Connecting the switch” on page 4
Power
If the power indicator on the front panel of the switch does not turn on when the power cord is
plugged in, the power outlet or power cord may be defective. Check to see that the power switch on
the rear panel is turned on (AP9224112 only.)
If the switch loses power after running for a while, check for loose power connections, or power
fluctuations at the power outlet.
Incorrect connections
The switch can auto-detect whether a device is connected with a straight-through or crossover cable.
If the RJ-45 connector pins are not properly configured, the link will fail. For a mini-GBIC
connection, make sure the fiber cable mode matches the mini-GBIC (SFP) transceiver.
Faulty or loose cables. Look for loose or faulty connections. Make sure the connections are snug.
If that does not correct the problem, try a different cable of the same category.
Non-standard cables. Check that you are using the correct cables.
See “Connecting the switch” on page 4.
Improper network topologies. Make sure that you are using a valid network topology. Too many
hubs or repeaters between the connected computers in the network may increase the number of
packet collisions or cause other network problems. Remove unnecessary hubs from the network.
Data path loops. Check for data path loops. There should be only one active cabling path at any
time between any two ends nodes.
APC Ethernet Switches: Installation, Troubleshooting, Specifications 15
Troubleshooting: Specific Problems and Their Solutions
Transmission Mode
The RJ-45 ports use auto-negotiation to set the transmission mode to either full-duplex or halfduplex.
Verify that each port is set to the same transmission mode used by the attached device. If the attached
device operates at half-duplex, the default when auto-negotiation fails, it does not support autonegotiation.
