Hardware Overview
The DECserver 700 connects devices (such as printers, terminals, PCs, and mo-
dems) to local area networks (LANs). The DECserver 700 is Ethernet/IEEE
802.3-based and supports standard Ethernet/IEEE 802.3 and 10BaseT Ethernet/
IEEE 802.3 directly, and ThinWireTM Ethernet/IEEE 802.3 through an adapter. The
DECserver 700 can be installed on a desktop or in a 19-inch rack. The DECserver
700 supports Flash RAM capability and other nonvolatile forms of memory. This
capability can be ordered separately and installed on the DECserver 700 in the field.
The DECserver 700 can download the software image from the network or from the
Flash RAM option if installed. The Flash RAM option allows for a boot/power up
withouthavingtodownloadtheimagethroughthenetwork.TheDECserver700will
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.
There are two DECserver 700 models:
•DECserver 700-08
•DECserver 700-16
1.1 Models
TheDECserver 700-08 supports EIA-232-D/V.24/V.28full modem control oneight
25-pin male D-connectors. Use this model to connect devices that require full du-
plex, asynchronous control (for example: modems).

1–2 Site Preparation and Maintenance
Figure 1–1showsarearviewoftheDECserver700-08.TheDECserver700-16sup-
ports EIA-423-A and DEC 423 data-leads on 16 MJ8 connectors. Use this model to
connectdevices requiring data-leads for operation (for example: terminals,printers,
and personal computers in terminal emulation mode). You can connect the DEC-
server to modems that do not require the full complement of signals provided by the
DECserver 700-08, using special adapters (Section 3.3).
NOTE
Adapters H8585-AB and H8585-AC are not for con-
nection to public networks in Sweden, Germany, or Ja-
pan.

Table 1–1 describes the DECserver 700 controls. Table 1–2 and Table 1–3 describe
the indicators, and Table 1–4 describes the connectors. For more information on the
connectors, refer to Chapter 4.

Control Description
System reset switch On power up, press this switch until E appears on the
seven-segment display. This reloads the factory set pa-
rameters. During Flash load, pressing and holding the
system reset switch will abort the Flash RAM load and
force a network boot. Refer to Chapter 7 for more informa-
tion.
Ethernet select switch This switch selects either standard or 10BaseT Ethernet.

1.3 Understand the Software Loading
This section describes the two methods that the DECserver 700 access to load the
software.
1.3.1 Loading from Flash RAM
Once the DECserver 700 completes self-tests, the DECserver 700 checks for Flash
RAM.Ifthere is a valid FlashRAM,the DECserver 700 beginsthebootsequence to
load the software from Flash RAM. The seven-segment display will display three
horizontal segments during this loading process.
If the DECserver 700 does not have Flash RAM, the DECserver 700 proceeds to a
network load.
If a device is connected to the console port, the DECserver 700 can display status
messageswhilethe boot sequence is running. Statusmessages indicate theEthernet
address of the DECserver 700, the name of the load image it is looking for, and the
stage of the boot process it is in.
1.3.2 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. When the system reset switch is pressed,
theFlash RAM loadwill be abortedand the softwareis downline loadedfrom a load
host.
When the DECserver 700 notices the system reset switch depressed during 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, refer to sec-
tion 7.7.

Checking the Site
The DECserver 700 can operate in an office environment and in a standard equip-
ment rack located in a computer room or satellite equipment room. Regardless of
where you install the DECserver 700, verify that all of the requirements in this sec-
tion are met before beginning the installation.
