Software Reference for detailed information on configuring the switch.
RS-232 Terminal Port (ASYN0)
This section introduces the switch’s RS-232 Terminal Port (ASYN0), including
its pin assignment and purpose.
The RS-232 ASYN0 Terminal Port is used to connect the switch to a
management device for initial configuration and switch management tasks.
This allows the switch’s software to be accessed from a terminal, a PC running
terminal emulation software, or from a remote location via a modem
connection. You can also use ASYN0 to establish a network connection from a
remote site using SLIP and a modem.
ASYN0 has a DCE female socket. This allows the use of a straight-through
cable when connecting the switch to a terminal or PC. Output from the SHOW
ASYN command will, however, still have a DTE perspective. The internal DTE
pin roles are listed in Table 3 on page 16.
See “Useful Cables” on page 16 for more information on suitable cables to use
with ASYN0.

Cables for RJ-45 Ethernet LAN Interfaces
For 10BASE-T/100BASE-TX/1000BASE-T (10/100/1000BASE) connections, a
twisted pair cable with four pairs and RJ-45 connectors must be used.
Table 5 on page 18 lists the cables used for network connections and testing of
RJ-45 interfaces.
Caution. Do not plug a phone jack into any RJ-45 port. Doing so could damage
the switch. Use only twisted pair cables with RJ-45 connectors.

For twisted pair cables each pair is identified by two different colours. For
example, one wire might be red, and the other red with a white stripe. An RJ-45
connector must be fitted to both ends of the cable. Figure 7 on page 18
illustrates the pin layout for RJ-45 connectors.

Test Facility
This section introduces the Test Facility. The Test Facility is built into all
AT-9800 Series software. For detailed information on operating the Test Facility,
see the Test Facility chapter of the AT-9800 Series Software Reference.
Any interfaces being tested are dedicated to the Test Facility. The Test Facility
can be thought of as a specialised interface module like PPP or Frame Relay.
Before using the test facility, disable any configurations (SET
CONFIGURATION=NONE) and restart or reboot the switch.

Ethernet LAN Port Tests
A crossover cable is required to run an Ethernet LAN test. See “Useful Cables”
on page 16 for details of how to make a suitable cable. To start the test, loop a
four-pair crossover or straight-through cable between any two RJ-45 ports and
enter:
ENABLE TEST INT=ALL
A loopback plug, instead of a crossover cable, can be used to test SC and MT-RJ GBIC
interfaces.
All interfaces connected by crossover cables are tested. Test results are
displayed with the command:
SHOW TEST
which produces a display like that shown in Figure 8 on page 20. A more
detailed output (with frame counts) can be displayed with the command:
SHOW TEST COUNT
which is shown in Figure 9 on page 21.

Redundant Power Supply (RPS)
RPS units enhance network reliability by providing backup coverage for switch
Power Supply Units (PSUs).
AT-9800 Series switches have an RPS connector on their rear panel. The
connector allows the switch to be used in conjunction with an RPS.
When an RPS is required, AT-9812TF and AT-9816GF models use the
AT-RPS8000 system, while AT-9812T and AT-9816GB models use the
AT-RPS9000 system. RPS systems can be purchased separately.

AT-9800 Series Switch
AT-RPS8000
The AT-RPS8000 is a chassis that holds up to four removable AT-PWR8000 RPS
units. To provide backup power to AT-9812TF and AT-9816GF switches, each
switch must be connected to an AT-PWR8000 power unit, and the power unit
must be installed in an AT-RPS8000 chassis.

A loose data cable.
■
The device at the other end of the connection is not working properly or is
turned off.
■
The data cable is not wired correctly.
■
The network administrator has manually disabled the port through the
software.
■
The port’s selected transmission mode does not match that of the attached
device.
Perform the following steps in sequence:
1.
Make sure the data cable connections are secure.
2.
Make sure the device at the other end of the connection is switched on and
working properly.
3.
Check that the data cable is wired correctly.
4.
If you can, log in and check the port status. See “To log In” on page 11 for
more information on how to log in.
5.
If the port is Enabled, make sure the transmission speed matches that of the
connected device (auto-negotiating, full or half-duplex).
If the port is disabled, someone has used the software to manually disable it. You should
find out why the port was disabled before enabling it.

RX and TX terminal locations on SC fibre GBIC ports are the reverse of RX and TX
terminal locations on fixed SC fibre ports. When looking at an SC fibre GBIC from the
front, the RX terminal is on the left and the TX terminal is on the right.
GBIC 1000BASE-T Auto-Negotiation
1000BASE-T GBICs support only 1000 Mbps full duplex connections. Although
1000BASE-T GBICs will participate in auto-negotiation processes, they will
only advertise 1000 Mbps. Half duplex, 10BASE-T, and 100BASE-TX modes are
not supported.
While 1000BASE-T GBICs will auto-negotiate at the copper Ethernet level, the
ports will behave as if in fixed 1000 Mbps full duplex mode. This is because the
SERDES connection used by GBIC ports makes the auto-negotiation invisible
to the switch, and so prevents a successful link negotiation.
When a 1000BASE-T GBIC is inserted into a GBIC slot, the port’s autonegotiation capability is disabled. This means that the port speed may not be
set to "auto-negotiate". If the port has been configured to auto-negotiate (by
default or by command) prior to the GBIC’s insertion, then this configuration is
overridden for as long as the GBIC remains in place.
Compact flash
AT-9800 Series switches have a compact flash slot on their rear panel. Compact
flash cards increase the flash memory available for file storage.
Compact flash files can be manipulated using the command line interface. Any
type of data, including releases, patches, GUIs and configurations can be stored
on compact flash cards. However, release, patch, and GUI files cannot be run
directly from compact flash. These files must be loaded into either NVS or
on-board flash.
Data contained on compact flash cards can be read with any compliant reader.
Do not keep sensitive data, for example keys, on compact flash cards.
Compact flash functionality is supported by software Release 2.5.1 and later.
Two compact flash cards have been approved for use with the AT-9800 Series
switch:
■
AT-CF032A-nnn 32MB CompactFlash card
■
AT-CF128A-nnn 128MB CompactFlash card
Where n is the number of cards in a package, less than 1000. A package
containing one card is 001.
For the latest list of approved compact flash cards, visit
www.alliedtelesyn.co.nz/support/at9800/.
Compact flash cards used on the switch must support a hardware access time of no more
than 100 nanoseconds. If a compact flash card does not meet the 100 nanosecond
requirement it may not work as this is the maximum bus timing allowed.

AT-9800 Series Switch
Installing and removing a compact flash card
Compact flash cards can be inserted into the compact flash slot at any time. CLI
messages are displayed when a card is inserted or removed. It takes
approximately two seconds for an inserted card to be initialised. Messages
notify the user when a card has been inserted:
Info (1106257): Compact flash card inserted.
and when the card is ready for use:
Info (1106268): Compact flash card initialisation successful.
A message notifies the user if the compact flash card is not compatible with the
switch:
Info (3106300): Compact flash card initialisation
unsuccessful.
When compact flash is in use, the compact flash Activity LED on the rear panel
of the switch is green.
Do not remove the compact flash card when it is being written to (that is, when
the compact flash Activity LED is lit). Doing so will corrupt data on the file
being written.
Testing a compact flash card
To display information about the basic state of a compact flash card, including
card size, file count and serial number, insert the card and enter the command:
SHOW CFLASH
To display cluster ranges on a card, insert the card and enter:
SHOW CFLASH TEST
Figure 12 on page 32 shows a sample output.

To test a card, insert the card and enter:
ENABLE CFLASH TEST START=startnumber END=endnumber
where startnumber and endnumber are positive integers within a cluster range.
The endnumber must be higher than the startnumber. Cluster ranges are
displayed in the output of the SHOW CFLASH TEST command (Figure 12 on
page 32).

The test software will read the file allocation table and display a list of free
sectors. Sectors can be tested as single sectors or as a range. The test will consist
of a write/read/verify cycle.
To stop the test, use the command:
DISABLE CFLASH TEST
To display the testing process while a test is in process, enter:
SHOW CFLASH TEST
Figure 13 on page 33 shows a sample output.

If used when testing is not active, the previous command displays blank
cluster ranges on a compact flash card (Figure 12 on page 32).
Error messages are displayed when a file write fails. Failure could be due to the
card being removed or an error in the card.
Content Addressable Memory (CAM)
AT-9800 Series switches ship with 40 k-entries of CAM, as standard. This
memory is divided into three fixed allocations:
•
8 k for MAC address tables
•
4 k for VLAN entries
•
28 k for all other L2/L3 tables (for example, IP route entries)
CAM can be expanded through the purchase and installation of lineCAM.
LineCAM is a 192 k-entry plug-in module that extends the switch’s Layer 2/
Layer 3 forwarding database from 40 k to 232 k. One lineCAM module can be
installed in each AT-9800 series switch.
When lineCAM is installed, the memory allocations are:
•
8 k for MAC address tables
•
4 k for VLAN entries
•
220 k for all other L2/L3 tables
LineCAM can be ordered as a pre-installed item when purchasing a switch, or
can be purchased separately.

To check how much CAM is installed, enter
SHOW SWITCH
For information on installing CAM, see “Restricted Procedures” on page 34.
Dual In-line Memory Modules (DIMMs)
Synchronous DRAM for AT-9800 Series switches is provided by a single
DIMM. Two memory sizes are supported, 128 MBytes and 256 MBytes.
Only Allied Telesyn supplied DIMMS have been tested and approved for use
with AT-9800 Series switches. Using DIMM that has not been approved may
cause unreliable operation and will invalidate the switch’s warranty.
To check how much DIMM is installed, enter
SHOW SWITCH
For information on installing DIMM, see “Restricted Procedures” on page 34.
Restricted Procedures
This section contains procedures that should only be performed by authorised
service personnel. Unauthorised use of procedures in this section may cause
danger of injury from electric shock, damage to the switch, and invalidation of
the product warranty.
If you would like to know more about the procedures outlined in this section,
please contact your authorised Allied Telesyn distributor or reseller.
Installing CAM
LineCAM is available as a 192 k-entry module. Adding a LineCAM module
extends the switch’s Layer 2/Layer 3 forwarding database from 40 k-entries to
232 k-entries. One LineCAM module can be installed in each AT-9800 series
switch.
LineCAM can be ordered as a pre-installed item when purchasing a switch, or
can be purchased separately and installed as needed.
For AT-9800 Series switches, CAM should only be installed by authorised
service personnel. Unauthorised opening of the switch’s lid may cause danger
of injury from electric shock, damage to the switch, and invalidation of the
product warranty.
To install LineCAM in an AT-9800 series switch:
1.
Avoid injury by working in a safe environment.
The workspace should be free of hazards, and there should be sufficient
room to lay out the switch, CAM, and tools.
C613-03059-00 REV E
Hardware Reference
35
2.
Unpack the CAM in an antistatic environment.
Do not attempt to install any hardware without observing correct antistatic
procedures. Failure to do so may damage the switch or CAM. If you are unsure
what the correct procedures are, contact your authorised Allied Telesyn
distributor or reseller.
3.
If fitted, disconnect the switch’s redundant power supply.
4.
Disconnect the mains power cord.
Before removing the switch’s lid, the power cord and, if connected, RPS power
cord should be disconnected to reduce risk of electrical shock.
5.
Remove all interface cables.
6.
Remove the switch’s lid.
The switch may need to be removed from any rack mounting system
before its lid can be removed.
Using a posidrive screwdriver, remove the 12 screws that secure the
switch’s lid. There are 5 screws located in countersunk holes on each side
of the lid, and 2 screws at the rear.
7.
Align the CAM.
Position the CAM over the CAM slot on the switch’s PCB. The three
support pillars located on the board should be aligned with the holes on
the CAM, and the CAM’s chamfers should be pointing to the switch’s PSU
(see Figure 14 on page 35).

AT-9800 Series Switch
Forcing a misaligned CAM will damage the CAM’s connector and CAM slot.
Press the CAM firmly into place. Secure the CAM to the support pillars
using the supplied screws.
The CAM is now ready to test.
Testing CAM
To check that the switch has recognised the CAM, turn on the switch and enter
the command:
SHOW SWITCH
to display system information, including the amount of CAM installed (see
Figure 15 on page 36 and Figure 16 on page 37).
If there is no entry for the CAM, or the entry displays an unexpected value,
then the switch has not correctly detected the CAM’s presence. The most likely
cause is that the CAM is not correctly plugged into the CAM slot. Repeat the
installation process, paying particular attention to the CAM alignment and
insertion steps.
Use the SHOW SWITCH command again, and if the display is still not correct,
contact your authorised Allied Telesyn distributor or reseller.

If any CAM test fails, check that the CAM is correctly installed in its slot and repeat the
tests. Contact your authorised Allied Telesyn distributor or reseller if the CAM does not
operate correctly.
Installing DIMM
AT9800 Series switches have one DIMM slot. The slot can be populated with
either a 128 MByte DIMM or a 256 MByte DIMM.
Only Allied Telesyn supplied DIMMS have been tested and approved for use
with AT-9800 Series switches. Using DIMM that has not been approved may
cause unreliable operation and will invalidate the switch’s warranty.
For AT-9800 Series switches, DIMM should only be installed by authorised
service personnel. Unauthorised opening of the switch’s lid may cause danger
of injury from electric shock, damage to the switch, and invalidation of the
product warranty.
To install DIMM in an AT-9800 series switch:
1.
Avoid injury by working in a safe environment.
The workspace should be free of hazards, and there should be sufficient
room to lay out the switch, DIMM, and tools.

5.
Remove the switch’s lid.
The switch may need to be removed from any rack mounting system
before its lid can be removed.
Using a posidrive screwdriver, remove the 12 screws that secure the
switch’s lid. There are 5 screws located in countersunk holes on each side
of the lid, and 2 screws at the rear.
6.
Prepare the DIMMs.
In an antistatic environment, remove the DIMM from its packing material.
Be sure to observe ESD precautions.
Do not attempt to install DIMM without observing correct antistatic
procedures. Failure to do so may damage the DIMM and switch. If you are
unsure what the correct procedures are, contact your authorised Allied Telesyn
distributor or reseller.
7.
To remove an existing DIMM.
Before removing the switch’s lid, the power cord and, if connected, RPS power
cord should be disconnected to reduce risk of electrical shock.
The DIMM is held in place by two retaining latches, one latch at each end
of the DIMM slot. Release these latches and carefully pull the DIMM from
the DIMM slot.
The DIMM slot’s location is shown in Figure 17 on page 39.

Align and insert the first DIMM.
Holding a DIMM at an angle of about 30 degrees from horizontal, align the
notches on its connector strips with the notches on an empty DIMM slot
(see Figure 18 on page 39).
Insert the DIMM into the DIMM slot, sliding it along the two DIMM
guides until the retaining latches automatically click into place. The latches
should hold the DIMM firmly in place.

Testing DIMM
The switch is unlikely to boot unless the DIMM is correctly installed. If the
switch does boot but you suspect the DIMM is malfunctioning, enter the
command to display the system information shown in Figure 19 on page 40:
SHOW SYSTEM
In the output’s memory section there should be an entry showing the size of
DRAM. If the DRAM size is less than the size of DIMM that has been installed,
then the switch has not correctly detected the DIMM. The most likely cause is
that the DIMM connector is not plugged into its slot correctly. Repeat the
installation process, paying particular attention to the DIMM insertion step.
C613-03059-00 REV E

AT-9800 Series Switch
After repeating the installation, use the SHOW SYSTEM command again, and
if the display is still not correct, contact your authorised Allied Telesyn
distributor or reseller.
If you have any difficulty with the DIMM at any time, contact your authorised Allied
Telesyn distributor or reseller and quote the serial numbers of both the base card on the
switch and the DIMM. The switch’s serial numbers and revision details can be read
using the SHOW SYSTEM command. It’s a good idea to record this information for
later reference.
