Chapter 1 Hardware Overview The Access Server 316 connects devices (such as printers, terminals, PCs, and modems) to local area networks (LANs). The Access Server 316 is Ethernet/IEEE 802.3-based and supports standard Ethernet/IEEE 802.3 and l0BaseT Ethernet/ IEEE 802.3 directly, and ThinWire Ethernet/IEEE 802.3 through an adapter. The Access Server 316 can be installed on a desktop or in a 19-inch rack. The Access Server 316 supports Flash RAM capability and other nonvolatile forms of memory.
Hardware Overview Model 316 The Access Server 316 supports TIA/EIA-423-B signal levels on 16 MJ8 connectors. Use the Access Server 316 to connect devices such as terminals, printers, modems, bar-code readers, or personal computers in terminal emulation mode. You can connect the Access Server 316 directly or, where required, using special adapters (see Chapter 3). NOTES Adapter H8585-AB and H8585-AC are not for connection to public networks in Sweden, Germany, or Japan. Figure 1-1.
Hardware Overview Figure 1-2. Access Server 316 Front View Table 1-1 describes the Access Server 316 controls. Table 1-1. Access Server 316 Controls Control Description System reset switch On power up, press this switch until E appears on the Seven-segment display. This reloads the factory set parameters. During Flash load (three horizontal segments of the Seven-segment LED), pressing and holding the system reset switch will abort the Flash RAM load and force a network boot.
Hardware Overview Table 1-3 describes the LEDs. Table 1-3. Network Activity LED Ethernet Selected Connection Status LED Display 10BaseT Open/incorrectly terminated OFF Correctly terminated/no network activity ON Correctly terminated/network activity Flashing (rate independent of network activity). Open on network activity OFF Correctly connected/no network activity OFF Correctly connected/network activity Flashing or ON, depending on network activity.
Hardware Overview Understanding the Software Loading This section describes the two methods for loading software. Loading from Flash RAM Once the Access Server 316 completes self-tests, it checks for Flash RAM. If there is a valid Flash RAM, the Access Server 316 begins the boot sequence to load the software from Flash RAM. The Seven-segment display will display three horizontal segments during this Flash RAM loading phase.

Replacing and Adding Memory 8. Remove the anti-static kit. 9. Replace the cover (Figure 5-8). Figure 5-8. Cover Replacement 10. Connect a terminal to the Access Server 316 (See section titled System OK LED Flashing on page 7-4.). 11. Reconnect the cables and test the Access Server 316. When you plug in the power cable, the Access Server 316 runs self-tests. After the tests are completed, the Access Server 316 requests a load from Flash RAM.
Replacing and Adding Memory Alternatively, connect a terminal to the console port of the Access Server 316, using 9600 baud, 8 bits, and no parity. Wait for the status messages to appear on the terminal indicating a Flash RAM load is in progress. Enter Ctrl-B twice on the keyboard. In response to the “>>>” prompt, enter the following command: >>>b eth:wweng2 If you are using a special load image file, use that file name in place of wweng2.
Replacing and Adding Memory NOTE The Access Server 316 supports only 36-bit-wide SIMs. If you are not using Cabletron Systems SIMs, check the specification of your SIM to verify that it is 36-bit-wide. SIMs that are not 36-bit-wide will not work but may not be detected by the Access Server 316 diagnostics. Installing Extra Memory To install a SIM: NOTE Step Action 1 Disconnect all cables from the Access Server 316. 2 Remove the Access Server 316 brackets, if fitted (Figure 5-1).

Replacing and Adding Flash RAM 10. Reconnect the cables and test the Access Server 316. When you plug in the power cable, the Access Server 316 runs a self-test. After the tests are completed, the Access Server 316 requests a load from Flash RAM. If Flash RAM is installed, three horizontal segments will be displayed. To abort Flash RAM load and to load from the network, press and hold the system reset switch until the display flashes.
Replacing and Adding Flash RAM Example Local> SHOW MEMORY CONFIGURATION Dynamic RAM: 4M bytes Non-Volatile RAM: 32K bytes Flash RAM: Installed: Yes Total size: 4M bytes Boot block: Valid Load image: Name: WWENG2 Size: 967756 bytes Version: V2.3 NOTE If Flash RAM is installed, but its boot block is invalid, then the total memory size will be displayed as zero. Your Flash RAM can also be updated with the INITIALIZE command. This command copies the load image to Flash RAM.

Chapter 7 What to Do If You Have Problems This chapter helps you identify and correct problems you may encounter during and after the installation of the Access Server 316 hardware. The troubleshooting procedures are for diagnosing and correcting hardware-related problems only. Notify the network manager if the troubleshooting procedures indicate the problem is software related or if the procedures do not correct the problem.
What to Do If You Have Problems Diagnosing Problems Compare the state of the Seven-Segment Display and the System OK LED with those shown in Table 7-1 and go to the section indicated for information on corrective action. NOTE On power up, the seven-segment display will show an “8”. Allow about 3 minutes to elapse before determining the state of the display. Table 7-1.
What to Do If You Have Problems Seven-Segment Display Off and System OK LED Off Problem(s) Correction(s) Power is not reaching the Access Server 316 hardware. 1. Secure the power cable at the Access Server 316 and at the wall outlet and check the fuse in the power cable plug (if applicable). 2. Check the wall outlet using another appliance or light, or plug the Access Server 316 power cord into another outlet. If power is not available at the wall outlet, check the wall outlet’s circuit breaker. 3.
What to Do If You Have Problems System OK LED Off / Seven-Segment Display Flashing Problem: A hardware error occurred that makes the Access Server 316 nonoperational. Correction: There is no corrective procedure for this problem except for SIM failure (refer to note). Notify the network manager that the Access Server 316 must be returned to Cabletron Systems for repair or replacement Refer to the Network Access Software Problem Solving guide for information about returning the unit to Cabletron Systems.
What to Do If You Have Problems Message: Local—941—Transceiver loopback error Problem: The Ethernet port has failed self-test. Correction: Determine which of the following corrections applies to your situation. • Standard Ethernet/ThinWire — Replace the cables or MAU. Test again by pulling out the power cord and re-inserting. If this corrects the problem, the fault is external to the Access Server 316.
What to Do If You Have Problems Seven-Segment Display Shows a “3” If the seven-segment display has a “3” after power up, the Access Server 316 has a downline loading problem. To isolate and diagnose the problem, do the following: 1. Connect a terminal to the console port of the Access Server 316, then power up the terminal. 2. Configure the terminal to operate with a speed of 9600 bits per second and a character size of 8 bits (no parity).
What to Do If You Have Problems Downline Load Does Not Start Messages: The following sequence of messages appears on the console terminal at various time intervals: Local—951—Network access server will retry operation in n seconds Local—953—[IP] Attempting to locate load host, [ETHERNET] Local—953—[MOP] Attempting to locate load host, [ISO8802] Local—953—[MOP] Attempting to locate load host, [ETHERNET] Problem: Load hosts are not responding to the Access Server 316 downline load request within the allotted
What to Do If You Have Problems 4 — Requesting load 3 — Load request backoff 2 — Loading I — Requesting dump O — Dumping H — Hardware revision number incompatible with firmware revision number N — No SIMs or wrong type SIMs installed Rotating — Access Server 316 is operating correctly Network Activity LED The following table shows the connection status for each type of LED display. Table 7-2.
