Hardware Reference 25 System LEDs Table 12: System LEDs found on all AT-9800 Series Switches.
26 AT-9800 Series AT-9812T and AT-9812TF LEDs Table 12: Port and GBIC LEDs on the AT-9812TF. LED State Function GBIC L/A Green A 1000 Mbps link is open. The link is operating in full duplex mode Flashing green 1000 Mbps full duplex activity is occurring Amber A 1000 Mbps link is open.
Hardware Reference 27 Check these first 1. Check the power cord connections. 2. Check that the power supply voltage is stable. 3. Check that the correct data cables are being used and that their connections are secure. 4. Check that any GBICs are correctly installed and that they are compatible with the switch. Some switch models have limitations on the number of GBICs that can be installed. See “Gigabit Interface Converters (GBICs)” on page 28 for more information. 5.
28 AT-9800 Series Power LED is OFF This can indicate: ■ A loose power cord. ■ A power supply failure. Perform the following steps in sequence: 1. Check that the power cord connections are secure. 2. Check that all switches and circuit protection devices are in the ON position. 3. Ensure that the supply voltage is within the operational range (110/240 VAC 50/60 Hz for AC models, 39-60 V DC for DC models). Fault LED is on This can indicate: ■ There is a problem with the switch or PSU.
Hardware Reference 29 Only tested and approved 5V Ethernet GBICs should be used with the AT-9800 Series switches. Any combination of copper and fibre GBICs can be installed in the following AT-9800 Series switches: • AT-9812T • AT-9812TF • AT-9816GB For the AT-9816GF, up to fourteen 1000BASE-T GBICs can be installed. The actual number depends on the number of fibre GBICs also installed.
30 AT-9800 Series While 1000BASE-T GBICs will auto-negotiate at the copper Ethernet level, the ports will behave as if in fixed 1000 Mbps full duplex mode. This is because the SERDES connection used by GBIC ports makes the auto-negotiation invisible to the switch, and so prevents a successful link negotiation. When a 1000BASE-T GBIC is inserted into a GBIC slot, the port’s autonegotiation capability is disabled. This means that the port speed may not be set to "auto-negotiate".
Hardware Reference 31 Restricted Procedures This section contains procedures that should only be performed by authorised service personnel. Unauthorised use of procedures in this section may cause danger of injury from electric shock, damage to the switch, and invalidation of the product warranty. If you would like to know more about the procedures outlined in this section, please contact your authorised Allied Telesyn distributor or reseller. Installing CAM LineCAM is available as a 192 k-entry module.
32 AT-9800 Series Using a posidrive screwdriver, remove the 12 screws that secure the switch’s lid. There are 5 screws located in countersunk holes on each side of the lid, and 2 screws at the rear. 7. Align the CAM. Position the CAM over the CAM slot on the switch’s PCB. The three support pillars located on the board should be aligned with the holes on the CAM, and the CAM’s chamfers should be pointing to the switch’s PSU (see Figure 14 on page 32). Figure 14: AT-9800 Series CAM slot and pillar mounts.
Hardware Reference 33 Use the SHOW SWITCH command again, and if the display is still not correct, contact your authorised Allied Telesyn distributor or reseller.

34 AT-9800 Series Installing DIMM AT9800 Series switches have one DIMM slot. The slot can be populated with either a 128 MByte DIMM or a 256 MByte DIMM. Only Allied Telesyn supplied DIMMS have been tested and approved for use with AT-9800 Series switches. Using DIMM that has not been approved may cause unreliable operation and will invalidate the switch’s warranty. For AT-9800 Series switches, DIMM should only be installed by authorised service personnel.
Hardware Reference 35 Do not attempt to install DIMM without observing correct antistatic procedures. Failure to do so may damage the DIMM and switch. If you are unsure what the correct procedures are, contact your authorised Allied Telesyn distributor or reseller. 8. To remove an existing DIMM. Before removing the switch’s lid, the power cord and, if connected, RPS power cord should be disconnected to reduce risk of electrical shock.
36 AT-9800 Series Figure18: Installing DIMM. DIMM CAM slot DIMM slot Ports Testing DIMM The switch is unlikely to boot unless the DIMM is correctly installed. If the switch does boot but you suspect the DIMM is malfunctioning, enter the command: SHOW SYSTEM to display the system information shown in Figure 19 on page 37. In the output’s memory section there should be an entry showing the size of DRAM.

38 AT-9800 Series To enable diagnostics mode: 1. Connect a terminal to the RS-232 Terminal Port (ASYN0). Using a terminal cable, connect a terminal to the RS-232 Port (ASYN0) on the switch. See “Useful Cables” on page 16 for more information on terminal cables. Set the terminal communication parameters to the following: 2. • Baud rate: 9600 • Data bits: 8 • Parity: None • Stop bits: 1 • Flow control: Hardware Restart the switch.
Hardware Reference 39 Table 14: Basic commands for running the diagnostics. Key Function Q Quits any running tests and displays the banner page. S Prints a summary of test results so far. A reasonable understanding of the system’s structure is needed to operate diagnostics and interpret the results. To restore the switch to normal operation, use a pen or pencil to operate the recessed reset button on the front panel, or press “0” (zero) to restart.
