MAX Administration Guide xvii
About This Guide
The MAX™ Administration Guide is intended to help you as you measure, maintain,
administer, and troubleshoot the performance of MAX 6000, MAX 3000, and MAX 800 units.
A reference to a specific MAX model always accompanies information that applies only to that
model. For example, if a description indicatesMAX 6000, then that information applies only to
MAX 6000 units. If a description indicates MAX, then that information applies to the MAX
6000, MAX 3000, or MAX 800 unit that is configured to support the feature being described.
To assure continuing satisfactory performance of a MAX unit make use of its indicator lights,
the VT100 interface, the terminal-server command-line interface (CLI), DO commands,
SNMP, and the Syslog.
!Warning: Before installing or operating your MAX unit, be sure to read the safety
instructions in the Edge Access Safety and Compliance Guide. For information specific to your
unit, see the “Safety-Related Electrical, Physical, and Environmental Information” appendix in
your unit’s hardware installation guide.
Navigation and usage of all the user interfaces are described in the Hardware Installation and
Basic Configuration Guide for your unit. You will continue to apply that information as you
use this guide.
The flexibility of the True Access™ Operating System (TAOS) software and hardware
architecture of the MAX base unit allows you to introduce services as you need them. The
MAX offers flash memory, slot cards, and software upgradable protocol support. You can
upgrade the features that the MAX unit supports by changing the version of TAOS software
running on the unit. The flexiblity of the system software and hardware architecture also
results in support for over 15 WAN protocols. The MAX also supports several virtual private
networking, several modem, and several bandwidth management protocols. Although the
flexibility of the unit’s TAOS software and hardware architecture can make the tasks quite
complicated, this guide intends to help you discern how best to assure satisfactory
performance. Use this guide to gather information about the performance of the MAX unit and
to eliminate problems that you may discover.
Note: This manual describes the full set of features for MAX 6000, MAX 3000, and MAX
800 units. Some features might not be available with earlier versions or specialty loads of the
software.

Administering MAX Hardware
From the moment you turn on the power and the MAX unit initiates a power-on self test
(POST), you can gather information that allows you to troubleshoot the MAX. Once the MAX
is running, you can interpret the indicator lights that the unit includes on its front panel and
back-panel. These indicator lights, combined with performance indicators, can lead you to
discover hardware and other issues such as problems with the configuration, the Ascend
Inverse Multiplexing (AIM) port, related Codec devices, and cables.
For E1, T1, and BRI interface-related information see Chapter 5, “Administering E1 and T1
Services” and Chapter 6, “Administering ISDN.”
Troubleshooting POST
A Power-on self test (POST) is a diagnostic test the MAX unit performs when it first starts up
or after it completes a system reset. During a POST, the unit checks system memory,
configuration, installed cards, compression hardware, and T1 connections.
If the start-up display indicates a failure in any part of the POST, an internal hardware failure
has occurred with the unit.
If no data is displayed on the VT100 interface, verify that the unit completes all of the
power-on self tests. Proceed as follows:
1Verify that the MAX unit and your terminal are set at the same speed.
2Locate the indicator light labeled Fault.
3Switch on the MAX unit.

Interpreting indicator lights
The MAX 6000, MAX 3000, and MAX 800 series each have a unique set of front panel
indicator and back-panel indicator lights that display information about modems, power
(including redundant power), fault-tolerance, data-link, and Alarm events.
MAX 6000
The MAX 6000 unit’s front-panel indicator lights indicate the status of the system, the PRI
interface, and the data transfer in active sessions. Figure 1-1 shows the location of the indicator
lights on the front panel of a MAX 6000 unit.
Figure 1-1. MAX 6000 front panel
Table 1-1 describes each indicator light located on the front panel of a MAX 6000 unit.
Table 1-1. MAX 6000 front-panel indicator lights
Light Description
Power On when the MAX 6000 unit’s power is on.
Fault On in one of two cases:
• Hardware self-test in progress.
• Hardware failure.
When a hardware self-test is in progress, the indicator light stays on. If any
type of hardware failure occurs, the indicator light flashes. If the failure is
isolated to an expansion card, the MAX 6000 unit might continue to function
without the expansion card.
Data On when calls are active.

The MAX 6000 unit’s front panel indicator lights convey information about the power supplies
and the status of the unit’s fans. Figure 1-2 shows the location of the indicator lights on the
front panel of a Redundant MAX 6000 unit.
Figure 1-2. Redundant MAX 6000 front panel
Table 1-2describes each indicator light on the front panel of a Redundant MAX 6000 unit.
Alarm On indicates a WAN alarm or a trunk out of service (during line loopback
diagnostics, for example). WAN alarms include Loss of Sync, Red Alarm,
Yellow Alarm, and All Ones (or AIS).
For more information about the Alarm indicator light, see“Troubleshooting a
Red Alarm” on page 5-2 and “Troubleshooting a blinking Alarm” on
page 5-4.
Table 1-2. Redundant MAX 6000 front panel lights
Light Description
Power On when the Redundant MAX power supply is on.
A Fail On only if one or more of the voltages from side A of the power supply
has failed (+12, +5, +3.3, -12, -5.)

The MAX 6000 unit’s back-panel indicator lights convey information about network traffic on
the unit’s Ethernet interface, packet collisions on the Ethernet network, full duplex operation
on the Ethernet network, 100BaseT (or 10BaseT) status, and the functional status of the
Ethernet interface. Figure 1-3 shows the MAX 6000 back-panel indicator lights, which display
the status of the Ethernet interface.
Figure 1-3. MAX 6000 back-panel indicator lights
Table 1-3 describes the MAX 6000 unit’s Ethernet interface indicator lights.
B Fail On only if one or more of the voltages from side B of the power supply
has failed (+12,+5, +3.3, -12, -5).
Fan On when the fans are functioning properly (if +12 Vdc from either A or
B is good). This indicator light goes off in the event of a fan failure.
Table 1-3. MAX 6000 back-panel indicator lights
Light Description
ACT (Activity) On when the MAX is detecting activity (network traffic) on its Ether-
net interface.
COL (Collisions) On when the MAX detects packet collisions on the Ethernet.
FDX On indicates full duplex on the Ethernet.
100BT On indicates 100BaseT operation. Off indicates 10BaseT operation.
LINK (Link integ-
rity) On when the Ethernet interface is functional.
