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. The Access Server 316 is shipped with Flash RAM installed. Should the
Flash RAM ever fail, it can be ordered separately and replaced on the Access
Server 316.

The Access Server 316 can download the software image from the network or
from the Flash RAM option. The Flash RAM option allows for a boot/powerup
without having to download the image through the network. The Access Server
316 will support up to 8 Mbytes of memory with the use of two single-in-line
modules (SIMs). These SIMs can be installed as memory updates by the customer.

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.

If the Access Server 316 does not have Flash RAM, or if the name of the image in
Flash RAM does not match the image name the Access Server 316 is attempting to
load, it proceeds to a network load.

Hardware Overview

If a device is connected to the console port, the Access Server 316 can display
status messages while the boot sequence is running. Status messages indicate the
Ethernet address of the Access Server 316, the name of the load image it is looking
for, and the current stage of the boot process.

Loading from the Network

If you do not want to load the software from Flash RAM, you can press the
system reset switch during load from Flash RAM (three horizontal segments
displayed on the Seven-segment display). When the system reset switch is
pressed, the Flash RAM load will be aborted and the software is downline loaded
from a load host.

When the Access Server 316 notices that the system reset switch depr essed during
a load from Flash RAM, it will rapidly blink the LED to acknowledge the pressed
system reset switch (this may take several seconds). Once the LED begins rapidly
blinking, you may release the system reset switch and the firmware will go on to a
network boot sequence. For more information on display codes for Flash RAM
(See section titled

Seven-Segment Display Codes

on page 7-7).

Replacing and Adding Memory

This chapter describes and illustrates the procedures for handling single-in-line
memory modules (SIMs) and Flash RAM when swapping out an Access Server
316 unit, and it shows how to replace a faulty SIM and add memory.

This chapter includes the following sections:

• Swapping or Replacing an Access Server 316 Unit

• Replacing a Faulty Single-In-Line Memory Module

• Additional Memory Supported

• Installing Extra Memory

Swapping or Replacing an Access Server 316 Unit

Whenever an Access Server 316 unit is replaced, the Single In-Line Memory
Modules (SIMs) and FLASH CARD must be REMOVED from the old unit and re­installed in the replacement. The removable Flash Card is used for installation of
the Network Access Software and is not required for the operation of the unit.

Before an Access Server 316 is swapped, assure that at least one memory SIM is
installed. Please refer to the following chapters for the correct procedure for
removing and installing SIMs and Flash Cards.

SIMs are sensitive to static and are packed in anti-static packaging. Electrostatic

!

CAUTION

Discharge (ESD) can cause failure of electronic components and can reduce the
long term reliability of the Access Server 316. Cabletron recommends that you use
an anti-static kit or ESD wrist strap when handling SIMs.

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.

If the SIM memory is faulty, the Access Server 316 flashed "C" if the faulty SIM

NOTE

is in connector 1 and "d" if the faulty SIM is in connector 2. If you install the
wrong type SIM, the Access Server 316 flashes "n". Remove or replace the SIM to
repair the Access Server 316.

12. Check status message 960 to verify memory size:
Local -960- Available memory 4 Mbytes

Additional Memory Supported

You can increase the memory of your Access Server 316 by adding extra single-in­line memory modules (SIMs). The Access Server 316 contains 4 Mbytes of SIM
memory. However, future releases of Access Server 316 software may contain
additional functions that require more SIM memory. You can install the additional
SIM memory on site. Adding an additional 4-Mbyte SIM will increase the
memory to the maximum of 8 Mbytes.

The Access Server 316 supports 4-Mbyte SIMs (1M x 36).
There are two SIM connectors on the Access Server 316 printed cir cuit board. One

of the connectors contains the factory installed 4-Mbyte SIM (Figure 5-4).
The Access Server 316 supports only SIMs with the following access times:

• 80 nano seconds

• 70 nano seconds

The Access Server 316 supports only SIMs in the following configurations:

• 4 Mbytes (one 4-Mbyte SIM in any connector)

• 8 Mbytes (one 4-Mbyte SIM per connector)

5-10

The Access Server 316 supports only 36-bit-wide SIMs. If you are not using

NOTE

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.
