Requirements
This document describes the procedure for installing
replacement firmware in a Model 3610 or 3611 Data
Service Unit (DSU). Follow the appropriate set of
instructions for either the Model 3610 or Model 3611
DSU.
Identity (ID) displays a report listing the DSU’s model
number, serial number, software/firmware version,
network address, DDS rate and installed options.
To see your firmware version:
. Procedure
1. Access the Status (Stat) branch from the front
panel.
2. Select ID. Press the key until the
DSU SW ver appears.
Prior to starting the installation, make a copy of the

The Model 3610 DSU firmware is located on the
EPROM under the front panel. To access the firmware,
perform the following steps:
. Procedure
1. Disconnect the ac transformer from the ac outlet
and the rear of the DSU.
2. Place a small screwdriver or your thumbs under
the two tabs on the outside edges of the front
bezel. Firmly press upward to separate the bezel
from the tabs.
3. Swing the front bezel up and set aside.

4. There is a notch on one end of the EPROM. Note
the location and orientation of the notch. Use the
proper EPROM extractor tool to carefully remove
the EPROM from the DSU circuit card and set the
EPROM aside.
WARNING
When installing the EPROM on
the DSU, ensure that the notch
on the EPROM is on the right.
Installing the EPROM in the
opposite direction will damage
the EPROM and cause
overheating, which may result
in possible injury to you.

5. Orient the replacement EPROM on the front panel
with the notch pointing to the right. Ensure that all
the pins in the EPROM are aligned and press into
place. Verify that the EPROM it is fully seated in
the connectors.
6. Reinsert the front bezel’s hinge tabs into position
at the top and swing the bezel down. Snap the
bezel back into place.

Powering Up the DSU
. Procedure
1. At the rear of the DSU, insert the round end of the
power cable into the receptacle labeled POWER.
2. Connect the 3-prong plug at the other end of the
cable to an ac outlet.
CAUTION
Only use the power
transformer designed for the
Model 3610 DSU. Using other
transformers may result in
personal injury or damage to
the equipment.
Power-Up Routine
When you apply power, the DSU performs a power-up
routine and:
•Determines what hardware options are installed, if
any. This may include DSU, DBM, and MUX.
•Automatically runs a Device Test on itself and each
installed hardware option. All front panel lights
flash on and off.
Continue if you receive successful messages. If a Fail
message appears or a hardware option does not appear,
refer to your User’s Guide, Document No.
3610-A2-GB46, for power-up messages and basic
procedures for changing configuration options and
troubleshooting.
To verify the new firmware version:
. Procedure
1. Access the Status (Stat) branch from the front
panel.
2. Select ID. Press the key until the
DSU SW ver appears.
3. Reinstall the factory configuration options (use the
FacC configuration for a control or FacT for a
tributary).
Note that the Health and Status (H/S) branch may
display a Confg Corrupt message. This message
will disappear when you reinstall the factory
configuration options.
4. Make any desired changes in the configuration
option sets using the Configuration Worksheets
prepared prior to replacing the firmware. Verify
that the network address and the DBM directories
are still correct. If not, make the appropriate
changes.

Model 3611 Firmware
Installation
To access the DSU to install the firmware in a
Model 3611 DSU, perform the following steps:
. Procedure
1. Use a Phillips screwdriver to loosen the screw
holding the circuit pack lock, and rotate the lock
to the open position. With a MUX card installed,
open both circuit pack locks. It is not necessary to
power down the carrier.

2. Pull out and down on the latch at the bottom of the
DSU’s faceplate until the circuit card starts to
come out of its slot in the carrier. Pull the DSU
circuit card free of the carrier and lay on a clean
flat work surface. When a MUX card is installed,
there are two latches to open. (See next section.)
Accessing a Model 3611 DSU with MUX
. Procedure
1. Remove the 3611 DSU with a MUX. The MUX
card for TDM or MCMP is attached to the DSU.
Together, the two cards use two carrier slots.

Powering Up the DSU
Power-up Routine
When you apply power to the DSU circuit card, the
DSU performs a power-up routine and:
•Determines what hardware options are installed,
including a DBM.
•Automatically runs a Device Test (Devic) on the
DSU and each installed hardware option.
Continue if you receive successful messages. If a Fail
message appears or a hardware option does not appear,
refer to your User’s Guide, Document No.
3610-A2-GB46, for power-up messages and basic
procedures for changing configuration options and
troubleshooting.
Verify Firmware Version
. Procedure
1. Access the Status (Stat) branch from the front
panel.
2. Select ID. Press the key until the
DSU SW ver appears.
3. Reinstall the factory configuration options (use the
FacC configuration for a control or FacT for a
tributary).
If the SDCP is installed and if the DSU’s carrier
and slot address location is the one selected at the
SDCP, the LCD displays the message Power-up
Tests.
Note that the Health and Status (H/S) branch may
display a Confg Corrupt message. This message
will disappear when you reinstall the factory
configuration options.
4. Make any desired changes in the configuration
option sets using the Configuration Worksheets
prepared prior to replacing the firmware. Verify
that the network address and the DBM directories
are still correct. If not, make the appropriate
changes.
