Installation Installing the Switch on a Desktop The Ethernet switch can be installed in a standard 19-inch rack or on a table or desktop. To install the switch in a rack, go to the section ‘Installing the Switch in a Rack’ on page 36. To install the switch as a table or desktop, perform the following steps: 1. Remove all components from the shipping package and store the packaging material in a safe location. 2. Locate a level, secure surface for the switch. 3.
AT-8216FXL, AT-8224XL, and AT-8288XL Series Installation Guide As power is applied to the switch, the Fault LED (shown in Figure 12) flashes as the switch runs a series of internal self tests. After the switch has finished running its self tests, the Fault LED will stop flashing and will remain OFF. Refer to the section ‘Switch LEDs’ on page 41 for information on all of the system and port LEDs. RS-232 TERMINAL PORT STATUS OL Fault LED FAULT RPS PWR RESET Figure 12 Fault LED 5.
Installation Installing the Switch in a Rack To install the Ethernet switch in a standard 19-inch rack, perform the following steps: 1. Remove all components from the shipping package and store the packaging material in a safe location. 2. To prepare the switch, place it on a level, secure surface. 3. If you purchased an expansion module for the switch, install the module by following the instructions in the section ‘Installing an Expansion Module’ on page 38. 4.
AT-8216FXL, AT-8224XL, and AT-8288XL Series Installation Guide Caution Air vents must not be blocked and must have free access to the room ambient air for cooling. " 13 6. Mount the switch in the rack using standard screws (not provided). 7. Apply AC power to the switch by plugging the power cord into the AC power connector on the back panel of the unit (shown in Figure 11) and plugging the other end into a power outlet. Warning The power cord is used as a disconnection device.
Installation Installing an Expansion Module This section contains instructions for installing an optional expansion module in the switch. An optional expansion module package should include the following items: # One expansion module # One quick install guide # Warranty card Note For information on cabling specifications for the expansion module, refer to the quick install guide shipped with the module. To install an expansion module, perform the following steps: 1.
AT-8216FXL, AT-8224XL, and AT-8288XL Series Installation Guide If you are installing only one expansion module in the switch, you should install the module in slot A (upper slot). While the module will work in slot B (bottom slot) with slot A empty, the port numbering assignments will change if you later install a module in slot A. This could affect the VLAN memberships on the switch and this could require you to adjust your VLAN configurations.
Installation Setting Up a Terminal for Local Management If you are installing the switch in a TCP/IP environment or if you intend to manage the switch from a remote site, you must first assign an IP address to the switch using the Omega management interface, which comes pre-installed on the switch along with the AT-S24 switch software. To start an Omega management session, perform the following steps: 1.
AT-8216FXL, AT-8224XL, and AT-8288XL Series Installation Guide Switch LEDs Table 3 describes the system LEDs on the Ethernet switch. Table 3 Switch System LED Status LED State Description Fault Solid Red The switch or management software is malfunctioning. Flashing Red The switch is booting, running diagnostic tests, writing messages to FLASH, or transferring files using XMODEM. OFF Normal operation.
Installation Warranty Registration When you have finished installing the switch, you should register your product by completing the enclosed warranty card and sending it in, or by visiting our web site at www.alliedtelesyn.com/forms/warranty.htm and completing the on-line registration.
AT-8216FXL, AT-8224XL, and AT-8288XL Series Installation Guide Where to Go Next Now that the switch is operational, you are ready to configure and monitor it as explained in the AT-S24 Management Software User’s Guide, which is available from Allied Telesyn’s web site at www.alliedtelesyn.com/support/prd_libs.htm.
Chapter 3 Troubleshooting This chapter provides information on how to detect and resolve problems with your switch.
Troubleshooting At the First Sign of a Problem Perform the following tasks when you first become aware of a problem with the switch: # Make sure the power cord is securely connected and the power voltage is not fluctuating. # Check the data cables for secure connections and make sure the device at the other end of a connection is operational. # Use Omega to read statistics and run diagnostics. For instructions, refer to the AT-S24 Management Software User’s Guide.
AT-8216FXL, AT-8224XL, and AT-8288XL Installation Guide Network Cabling Problems If you have 10/100Base-TX (Fast Ethernet), some network problems may be related to exceeding cabling distances. Refer to the standard IEEE 802.3u, Clause 29.3.1.2 on Worst Case Path Delay Value. This document specifies that the collision domain diameter must be within the following limits: # Under 100 meters (328 feet) for TX cabling # Under 412 meters (1,331.
Troubleshooting Calling Technical Support When contacting Allied Telesyn for support on any of its products, you will need to provide Technical Support with the following information: # Model and serial number # Software version number # Description of the problem Refer to Allied Telesyn’s web site at www.alliedtelesyn.com for a list of worldwide locations.
AT-8216FXL, AT-8224XL, and AT-8288XL Installation Guide How the Switch Reports Problems The switch detects and processes errors as follows: # The LEDs indicate problems with the ports and power. For information on the LEDs, refer to ‘Switch LEDs’ on page 41. # In a TCP/IP environment, if you have configured the software correctly, the management software triggers an SNMP trap message. As a result, the software then sends traps to alert the network manager when a trigger occurs.
Troubleshooting Common Problems This section lists common possible sources of errors and the actions required to correct them. Link /Activity LED on Any Port is OFF This can indicate: # A loose data cable. # The device at the other end of the connection is powered OFF. # The 10/100Base-TX data cable is not wired correctly (straight/ crossed) for the device. # The port’s selected transmission mode does not match that of the attached device.
AT-8216FXL, AT-8224XL, and AT-8288XL Installation Guide Perform the following steps in sequence; you need not proceed to the next step if the problem is resolved: 1. Secure the power cord to the power source and check the Power LED to see if it is ON. 2. Ensure that the voltage is within the required levels in your region. 3. If possible, logon to Omega and run Diagnostics if you can (Administration>Diagnostics ) and record any failures. 4. Contact Allied Telesyn’s Technical Support for assistance.
