T HE CSX7000
OVERVIEW
The CSX7000, the high availability, remote access switch, is a multi-system platform intended for
large, central sites and Internet Service Providers. It is both modular and flexible, with capabilities
and performance to match the requirements of high-end network connectivity customers. The
CSX7000 supports a high density of LAN segments, ISDN BRI or PRI, and digital modems, as well
as RS232, V.35, Frame Relay and X.25 interfaces. It also offers an effective means of system
management through its optional Environmental Management System (EMS) module.
Modularity: An important feature of the CSX7000 is its ability to support multiple system groups.
Each group is a stand-alone CSX “system” based on a Pentium processor module. Use the sixteen
ISA slots of the CSX7000 as a single system group, or partition it into as many as four system
groups. A combination of modules (including a processor module) makes up a system group.
Flexibility: The CSX7000 supports a flexible setup for system groups; mix and match individual
LAN and WAN interface modules within a group to support specific needs.
High Availability: Local Area Network (LAN) and Wide Area Network (WAN) interface modules
have their own dedicated on-board processors and memory, thus lessening the load on the main
processor. TDM and MVIP bus connections allow the transfer of data between cards to improve
throughput without using the ISA bus.
The fault-tolerant platform provides redundant, hot-swappable power supplies and cooling fans.
The platform supports bus segmentation and load sharing. For backup or parallel operations,
configure redundant system groups.
Environmental Management: The platform contains intelligent environmental sensors to monitor
power, temperature and other environmental functions.

T HE CSX7000
The CSX7000 Chassis
THE CSX7000 CHASSIS
The CSX7000 is a self-contained 16 slot rack-mount unit with a passive segmentable backplane. It
can support multiple system groups using multiple processor modules. It is capable of running
completely independent applicationswithin the same chassis. An internal, multiplexed bus system
allows all processor modules within the chassis to share a single flexible disk, monitor, and
keyboard.
The CSX7000 is built with heavy industrial material and includes a cooling system which can
accommodate the full chassis. Thetwo redundant integral power suppliesprovide high availability
processing. You can hot swap each supply without affecting the CSX7000’s functions. You can
power on or off individual groups, which allows you to maintain a selected group while other
groups in the chassis remain operational.
The CSX7000 contains a slide rail assembly to allow for its mounting in a 19 inch RETMA rack or
cabinet. (Refer to chassis dimensions and rack/cabinet recommendations.) You can create a cluster of
CSX7000s by stacking multiple chassis and connecting them with a chassis-to chassis daisy chain
bus. (See following illustration.)
PROCESSOR MODULE
Cabletron offers two different processor modules for the CSX7000: the CSXPRO-8 and the
CSXPRO-32. These Pentium single-board CPUs are self-contained computers that include
processor, memory, and I/O. The amount of RAM and the speed of the processor differentiate the
available CPUs:
• CSXPRO7-8 sufficient for most remote access applications
• CSXPRO7-32 for densely-populated PRI configurations
ENVIRONMENTAL MODULE
For each cluster of connected CSX7000s, an optional Environmental Management System (EMS)
module manages the intelligent environmental sensors located throughout the cluster. These
sensors monitor system status, including CPU operation, voltages, fuses, temperature and fans.
TheEMS module can monitorandcontrol up to31 CSX7000s connected asa singlecluster.The EMS
module can also be configured as an SNMP agent for management of the environmental sensors
through a remote SNMP manager.
INTERFACE MODULES
The CSX7000 supports multiple interface modules. These interface modules combine with a
processor module to form a system group. The interface modules can include:
• Ethernet Local Area Network (LAN) Interface (single port or two port)
• ISDN Basic Rate Interface (BRI)
• ISDN Primary Rate Interface (PRI)
• digital modem (DM-8, DM-24, DM-24+, DM-30+)
• dedicated line connectivity through RS232 and V.35
• Frame Relay and X.25 support
For detailed information on these and other features of the CSX7000, refer to the User’s Guide.

CSX7000 Front Panel
CSX7000 FRONT PANEL
The front panel of the CSX7000 consists of the following:
•push buttons which control a BC Group and Video Select
•LED indicators which identify operation of power supply, fans, environmental sensors and data
highway (EMS bus)
• recessed Group Power, Group Reset, and Audible Clear switches
• a master console key lock
• a 3.5" flexible disk drive
Refer to the following illustrations and the descriptions of each element on the front panel. In
addition to the front panel LEDs, there is also a series of interior LEDs.
BC GROUP PUSH BUTTONS
BC GROUP refers to the segmented backplane position for a group of cards that make up a system.
BC stands for Bus Controller, which is the name of the processor module (or single board computer)
which runs the specific system within the CSX7000. Group refers to the system group of slots
isolated on the backplane; these slots are connected together and contain a processor module. Up
to four system groups are supported per CSX7000.
The BC GROUP push buttons are the top two push buttons in the group of six. (See top right corner
of the front panel). Use the BC GROUP push buttons to selecta particular group for observation or
administration when video is enabled. By pressing the up and down BC GROUP push buttons,you
can switch between thepossible groupswithin the platform. Theindicators to the rightof the push
buttons display the number of the currently-selected group. (Note that the systems are numbered
1 to 4 from the left to the right in the backplane as viewed from the front of the platform.)
When a group is selected, its channel on the multiplexor is enabled, connecting this module to the
monitor/keyboard bus and the local flexible disk drive. Several of the other front panel operations
apply only to the group selected.

The group numbers correspond to the number of systems configured on the backplane. You may
need to reset this value (i.e., enter Autoconfiguration Mode) due to a change in your backplane
segmentation. To do so, perform the following:
• Power down the CSX7000.
• Power up the CSX7000. Press and hold the BC Group “select up” button during the first 5 sec-
onds of the initial power-up cycle.
The BC Group numbers will then reset per the current backplane configuration.
MULTIPORT BOARD / MP SERIAL PORT PUSH BUTTONS
These four remaining push buttons (in the group of six) are not used with the CSX7000.
GROUP POWER SWITCH
The selected group may have the power turned on or off via the recessed GROUP POWER switch
on the front panel. This power on/off function is operational only for the specific group selected
(with BC GROUP push buttons) and only if the console is unlocked. This switch allows you to turn
off a specific group for maintenance purposes while other groups continue to operate.
BC RESET SWITCH
Individual groups may be reset using the BC RESET switch. The BC RESET switch is recessed to
prevent accidental resets. This reset function is operational onlyfor the specific group selected (with
BC GROUP push buttons), and only if the console is unlocked.
WARNING:
Eventhough BC RESET is available, we do not recommend its use with the CyberSWITCH
system groups. We recommend individual power on/off cycles to ensure proper system
reset/restart.
AUDIBLE CLEAR SWITCH
AUDIBLE CLEAR is a recessed push-button switch. It is used to clear an environmental alarm only
if an audible alarm is enabled by BCVision.
When an environmental parameter exceeds its system limits, the environmental alertLED displays
an amber light, and an audible alarm sounds. This alarm continues to sound until the
environmental parameter again falls within system limits, or the AUDIBLE CLEAR switch is
pressed.

BACKPLANE
The backplane will accommodate a total of four system groups through its 16 adapter slots. The
backplane slots are numbered 1 through 16, right to left, as viewed from the rear panel. The slots
are electrically connected in pairs of two: slots 1 and 2, slots 3 and 4, and so on. Therefore, the
backplane is configurable in multiple groups of two slots each, resulting in configurations of 2, 4, 6 or
8 slots per group. The processor module should always be located in the first slot of the group.
In most installations, slot one will provide connections for the processor module for the first group,
and slot fifteen will provide connections for the EMS processor module. Note that slot 15 is always
used for the EMS when the EMS is present.
SYSTEM MONITORING CONNECTORS
The Environmental Management System (EMS) manages all the intelligent sensors located
throughout the cluster of CSX7000s. In order to function, the EMS must properly connect to each
CSX7000 within the cluster.
The EMS connections consist of RJ-11 jacks located on the upper-left side of the back panel. The
EMS module itself is identified as IES Supervisor, and has an IN and OUT connection. To the left
of the IES Supervisor is the connection to the IES circuitry for the individual platform (subsystem).
These IN and OUT connections are in a vertical position, and are labelled IES. For more
information, refer to EMS and Monitoring Systems.
If multiple CSX7000s make up a cluster, IES connections are daisy-chained together. Refer to
CSX7000 Cabling for further details.
VIDEO CONNECTORS
The monitor connections (i.e., VIDEO) are located to the left of the back panel, and are labelled
VIDEO IN and VIDEO OUT. The VIDEO OUT connection of the firstCSX7000 connects to the video
monitor, while the VIDEO IN connection connects to the VIDEO OUT ofthe second CSX7000 in the
cluster. This type of daisy-chain connection continues throughout the cluster. Refer to CSX7000
Cabling for further details.
POWER SUPPLY
To the far left of the back panel is a vertical column for the power supply bay. The bay houses dual
350 watt powersupplies (PS1and PS2), which providefault tolerancein the eventof a singlepower
supply failure. Each power outlet on the CSX7000 can be connected to a separate power source for
additional protection. Once the outlets are properly connected to an AC power source, the power
supplies may be controlled by the switches above the outlets.

POWER SUPPLY AND COOLING SYSTEM
The CSX7000 is built with heavy industrial material including a cooling system which can
accommodate a full chassis. The cooling system includes two fans specifically for the boards and
drives, and two fans for the power supplies.
The CSX7000 has two redundant power supplies providing fault tolerant processing. Both power
supplies should always be operational. The power supplies are set up to share the power load of
the platform (subsystem), yet each power supply is big enough to manage the entire power load, if
necessary. Each supplycanbe powered offand replaced without affecting the CSX7000’s functions.

The power supply is contained in a canister type of enclosure to make the replacement as easy as
possible. (See Power Supply Installation for details.)
Note that there are two LEDs on each power supply: one red and one green. When power is on, the
green LED is lit to indicate a no-fault condition. If power is on and the red LED is lit, a problem
exists. If power is off, the LEDs will not light.
BACKPLANE BAY
The segmentable CSX7000 ISA backplane technologyis based on the concept of joining or shunting
groups of slots together. The backplane consists of eight groups of paired slots that are isolated: a
total of 16 slots. These paired slots can be electrically joined together with special shunt boards
inserted between the standard ISA slots.
An ISA strain relief cross-bar runs across the top of the cards in the backplane. This bar is intended
to stabilize the backplane to avoid intermittent connections. This is especially valuable in cabinet
or rack setups in which the unit may be pushed in and pulled out repeatedly.
