•
The module is released from reset by the supervisor engine and is booting.
•
The boot code failed to run.
Orange
Indicates one of the following conditions:
•
The module is initializing hardware or communicating with the supervisor engine.
•
A fault occurred during the initialization sequence.
•
The module failed to download its Field Programmable Gate Arrays (FPGAs) at startup. The module continues with the remainder of the initialization sequence and provides the module online status from the supervisor engine.
•
The module has not received the module online status from the supervisor engine. This problem may be caused by the supervisor engine detecting a failure in an external loopback test that it issued to the module.
Green
The module is operational; the supervisor engine has provided module online status.
Green to Orange
The module is disabled through the supervisor engine command-line interface (CLI) using the no power enable module command.
1 Enter the show environment temperature mod command at the Catalyst 6500 series switch or Cisco 7600 series router CLI to display the temperature of each of the four sensors on the module.
Shutdown Button
CautionDo not remove the ACE module from the Catalyst 6500 series switch or the Cisco 7600 series router until the module has shut down completely and the Status LED is orange. To avoid damaging the ACE module, you must correctly shut down the module before you remove it from the chassis or before you disconnect the power. You may damage the ACE module if you remove it from the switch before it completely shuts down.
The Shutdown button manually shuts down the ACE module. To properly shut down the ACE module to prevent data loss, enter the no power enable module command in Configure mode at the switch or router CLI.
If the ACE module fails to respond to this command, shut down the module by using a small pointed object (such as a paper clip) to access the Shutdown button on the front panel of the ACE module. The shutdown procedure may take several minutes. The Status LED turns off when the module shuts down.
USB Port
The USB port is intended for future use.
RJ-45 Console Connector
The RJ-45 Console port is used to initially configure the ACE module. The initial ACE module configuration must be made through a direct connection to the Console port. After the initial configurations, you can make an Secure shell (SSH) or Telnet connection to the module to further configure it.
The Console port uses an 8-pin RJ-45 connector to connect the ACE module to a terminal. Two RJ-45 console cables are included as part of the ACE module accessory kit.
The settings for the Console port are 9600 baud, 8 data bits, 1 stop bit, no parity. The Console port settings are fixed and cannot be changed.
FIPS LED
The Federal Information Processing Standards (FIPS) LED is not used. This LED is on the front panel of an ACE10-6500-K9 module only.
System and Environmental Requirements
The following sections describe the system and environmental requirements for the ACE module:

When you handle a module, always use a wrist strap or other grounding device to prevent electrostatic discharge (ESD).
CautionDuring this procedure, wear grounding wrist straps to avoid ESD damage to the modules.
CautionDo not directly touch the backplane with your hand or any metal tool or you may shock yourself.
All Catalyst 6500 series switches and Cisco 7600 series routers support hot swapping, allowing you to install, remove, and replace modules without turning off chassis power. For more information on removing the modules from a switch, see the "Removing a Module" section.
When the software detects that a module has been installed or removed, it automatically runs diagnostic and discovery routines, acknowledges the presence or absence of the module, and resumes switch operation.
The Catalyst 6503 or 6503-E switch chassis has three horizontal slots. The Catalyst 6504 or 6504-E switch, or Cisco 7604 router chassis has four horizontal slots. In these chassis, the slots can be used as follows:
•
Slot 1, the top-most slot, is reserved for the supervisor engine.
•
Slot 2 can be used for a redundant supervisor engine.
•
If a redundant supervisor engine is not required, the following slots are available for modules:
–
Slots 2 and 3 on the 3-slot chassis
–
Slots 2 through 4 on the 4-slot chassis
•
Empty slots require filler panels to maintain consistent airflow through the chassis.
The Catalyst 6506 or 6506-E switch, or Cisco 7606 router chassis has six horizontal slots. The Catalyst 6509 or 6509-E switch chassis has nine horizontal slots. The Catalyst 6509-NEB and Catalyst 6509-NEB-A switches or the Cisco 7609 router have nine vertical slots, which are numbered 1 to 9 from right to left. Install vertical modules with the component side facing to the right. In these chassis, the slots can be used as follows:
•
Slot 5 is reserved for the supervisor engine.
•
Slot 6 can be used for a redundant supervisor engine.
•
If a redundant supervisor engine is not required, the following slots are available for modules:
–
Slots 1 through 4 and slot 6 on the 6-slot chassis
–
Slots 1 through 4 and slots 6 through 9 on the 9-slot chassis
•
Empty slots require filler panels to maintain consistent airflow through the switch chassis.
The Catalyst 6513 or 6513E switch or Cisco 7613 router chassis has 13 horizontal slots. In these chassis, the slots can be used as follows:
•
Slot 7 is reserved for the supervisor engine.
•
Slot 8 can be used for a redundant supervisor engine.
•
If a redundant supervisor engine is not required, slots 1 through 6 and slots 8 through 13 are available for modules.
•
Empty slots require filler panels to maintain consistent airflow through the chassis.
Installing a Module
This section describes how to install an ACE module in a Catalyst 6500 series switch or a Cisco 7600 series router.
WarningInvisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments.
CautionTo prevent ESD damage, handle modules by the carrier edges only.
CautionDuring this procedure, wear grounding wrist straps to avoid ESD damage to the module. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself.
To install a module in the chassis, perform these steps:
Step 1
Choose an appropriate slot for the module.
Step 2
Verify that there is enough clearance to accommodate any interface equipment that you will connect directly to the module ports. If possible, place the modules between the empty slots that contain only the module filler panels.
Step 3
Verify that the captive installation screws are tightened on all modules installed in the chassis. This action ensures that the EMI gaskets on all modules are fully compressed to maximize the opening space for the replacement module.
Note
If the captive installation screws are loose, the EMI gaskets on the installed modules push adjacent modules toward the open slot, reducing the opening size and making it difficult to install the replacement module.
Step 4
Remove the filler panel by removing the two Phillips pan-head screws from the filler panel.
Step 5
Open both ejector levers fully on the module (see Figure 3).
Figure 3 Positioning the Module in a Horizontal Slot Chassis
Step 6
Depending on the orientation of the slots in the chassis (horizontal or vertical), perform one of the following sets of substeps:
Horizontal slots
a.
Position the module in the slot. Ensure that you align the sides of the module carrier with the slot guides on each side of the slot (see Figure 3).
b.
Carefully slide the module into the slot until the EMI gasket along the top edge of the module makes contact with the module in the slot above it and both ejector levers have closed to approximately
45 degrees with respect to the module faceplate (see Figure 4).Figure 4 Clearing the EMI Gasket in a Horizontal Slot Chassis
c.
Using the thumb and forefinger of each hand, grasp the two ejector levers and press down to create a small (0.040 inch [1 mm]) gap between the EMI gasket and the module above it (see Figure 4).
CautionDo not press down too firmly on the levers because you may bend or damage them.
d.
While pressing down on the left and right ejector levers, simultaneously close them to fully seat the module in the backplane connector. The ejector levers are fully closed when they are flush with the module faceplate (see Figure 5).
Figure 5 Ejector Levers Fully Closed in a Horizontal Slot Chassis
Note
Failure to fully seat the module in the backplane connector may result in error messages.
e.
Tighten the two captive installation screws on the module. Make sure that the ejector levers are fully closed before tightening the captive installation screws.
When you install an ACE module into a chassis, it runs a startup sequence that requires no intervention. At the successful conclusion of the startup sequence, the green Status LED lights and remains on. If the Status LED is not green or is off, see Table 4 to determine the module status.
Vertical slots
a.
Position the module in the slot (see Figure 6). Make sure that you align the sides of the module carrier with the slot guides on the top and bottom of the slot.
Figure 6 Positioning the Module in a Vertical Slot Chassis
b.
Carefully slide the module into the slot until the EMI gasket along the right edge of the module makes contact with the module in the slot adjacent to it. Close both ejector levers to approximately 45 degrees with respect to the module faceplate (see Figure 6).
c.
Using the thumb and forefinger of each hand, grasp the two ejector levers and exert a slight pressure to the left, deflecting the module approximately 0.040 inches (1 mm) to create a small gap between the module EMI gasket and the module adjacent to it (see Figure 7).
Figure 7 Clearing the EMI Gasket in a Vertical Slot Chassis
CautionDo not exert excessive pressure on the ejector levers because you may bend or damage them.
d.
While pressing on the ejector levers, simultaneously close them to fully seat the module in the backplane connector. The ejector levers are fully closed when they are flush with the module faceplate (see Figure 8).
Figure 8 Ejector Levers Fully Closed in a Vertical Slot Chassis
e.
Tighten the two captive installation screws on the module. Make sure that the ejector levers are fully closed before tightening the captive installation screws.
When you install an ACE module into the chassis, it runs a startup sequence that requires no intervention. At the successful conclusion of the startup sequence, the green Status LED lights and remains on. If the Status LED is not green or is off, see Table 4 to determine the module status.
Removing a Module
This section describes how to remove an existing module from a chassis slot.
WarningInvisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments.
CautionDuring this procedure, wear grounding wrist straps to avoid ESD damage to the module.
CautionDo not directly touch the backplane with your hand or any metal tool or you may shock yourself.
To remove a module from the chassis, perform these steps:
Step 1
Before you remove the module from the chassis, enter the no power enable module command in configure mode at the switch or router CLI to properly shut down the module to prevent data loss.
Step 2
Verify that the captive installation screws on all of the modules in the chassis are tight.
This step assures that the space that is created by the removed module is maintained.
Note
If the captive installation screws are loose, the electromagnetic interference (EMI) gaskets on the installed modules push the modules toward the open slot, reducing the opening size and making it difficult to reinstall the module.
Step 3
Loosen the two captive installation screws on the standby module. See Figure 9.
Figure 9 Loosening the Captive Installation Screws on the ACE
Step 4
Depending on the orientation of the slots in the chassis (horizontal or vertical), perform one of the following sets of substeps:
•
Removing the ACE from a Horizontal Slot
•
Removing the ACE from a Vertical Slot
Removing the ACE from a Horizontal Slot
a.
Place your thumbs on the left and right ejector levers, and simultaneously rotate the levers outward to unseat the module from the backplane connector.
b.
Grasp the front edge of the module with one hand, and slide the module part of the way out of the slot. Place your other hand under the module to support its weight. Do not touch the module circuitry. See Figure 10.
Removing the ACE from a Vertical Slot
a.
Place your thumbs on the ejector levers that are located at the top and bottom of the module, and simultaneously rotate the levers outward to unseat the module from the backplane connector.
b.
Grasp the edges of the module, and slide the module straight out of the slot. Do not touch the module circuitry.
Figure 10 Removing the Module from a Horizontal Slot Chassis
Step 5
Place the module on an antistatic mat or antistatic foam, or immediately reinstall it in another slot.
Step 6
If the slot from which you removed the module is to remain empty, install a filler panel to keep dust out of the chassis and to maintain proper airflow through the chassis.
WarningBlank faceplates (filler panels) serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards and faceplates are in place.
Accessing the ACE Command-Line Interface
The software interface for the ACE module is the command-line interface (CLI). You access the ACE module CLI by performing one of these tasks:
•
Establishing a direct serial connection between your terminal and the ACE by making a serial connection to the console port on the front of the ACE.
•
Establishing a remote connection using the SSH or Telnet protocols from a PC.
Unless your Catalyst 6500 series switch or Cisco 7600 series router is located in a fully trusted environment, we recommend that you configure the ACE module using SSH encryption.
See the Cisco Application Control Engine Module Administration Guide for details about accessing the ACE module, performing initial set up, and establishing remote access.

Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029
Waarschuwing
Lege vlakplaten en afdekpanelen vervullen drie belangrijke functies: ze voorkomen blootstelling aan gevaarlijke voltages en stroom binnenin het frame, ze bevatten elektromagnetische storing (EMI) hetgeen andere apparaten kan verstoren en ze leiden de stroom van koellucht door het frame. Het systeem niet bedienen tenzij alle kaarten, vlakplaten en afdekkingen aan de voor- en achterkant zich op hun plaats bevinden.
Varoitus
Tyhjillä tasolaikoilla ja suojapaneeleilla on kolme tärkeää käyttötarkoitusta: Ne suojaavat asennuspohjan sisäisille vaarallisille jännitteille ja sähkövirralle altistumiselta; ne pitävät sisällään elektromagneettisen häiriön (EMI), joka voi häiritä muita laitteita; ja ne suuntaavat tuuletusilman asennuspohjan läpi. Järjestelmää ei saa käyttää, elleivät kaikki tasolaikat, etukannet ja takakannet ole kunnolla paikoillaan.
Attention
Ne jamais faire fonctionner le système sans que l'intégralité des cartes, des plaques métalliques et des panneaux avant et arrière ne soient fixés à leur emplacement. Ceux-ci remplissent trois fonctions essentielles : ils évitent tout risque de contact avec des tensions et des courants dangereux à l'intérieur du châssis, ils évitent toute diffusion d'interférences électromagnétiques qui pourraient perturber le fonctionnement des autres équipements, et ils canalisent le flux d'air de refroidissement dans le châssis.
Warnung
Blanke Faceplates und Abdeckungen haben drei wichtigen Funktionen: (1) Sie schützen vor gefährlichen Spannungen und Strom innerhalb des Chassis; (2) sie halten elektromagnetische Interferenzen (EMI) zurück, die andere Geräte stören könnten; (3) sie lenken den kühlenden Luftstrom durch das Chassis. Das System darf nur betrieben werden, wenn alle Karten, Faceplates, Voder- und Rückabdeckungen an Ort und Stelle sind.
Avvertenza
Le piattaforme bianche e i panelli di protezione hanno tre funzioni importanti: Evitano l'esposizione a voltaggi e correnti elettriche pericolose nello chassis, trattengono le interferenze elettromagnetiche (EMI) che potrebbero scombussolare altri apparati e dirigono il flusso di aria per il raffreddamento attraverso lo chassis. Non mettete in funzione il sistema se le schede, le piattaforme, i panelli frontali e posteriori non sono in posizione.
Advarsel
Blanke ytterplater og deksler sørger for tre viktige funksjoner: de forhindrer utsettelse for farlig spenning og strøm inni kabinettet; de inneholder elektromagnetisk forstyrrelse (EMI) som kan avbryte annet utstyr, og de dirigerer luftavkjølingsstrømmen gjennom kabinettet. Betjen ikke systemet med mindre alle kort, ytterplater, frontdeksler og bakdeksler sitter på plass.
Aviso
As faces furadas e os painéis de protecção desempenham três importantes funções: previnem contra uma exposição perigosa a voltagens e correntes existentes no interior do chassis; previnem contra interferência electromagnética (EMI) que poderá danificar outro equipamento; e canalizam o fluxo do ar de refrigeração através do chassis. Não deverá operar o sistema sem que todas as placas, faces, protecções anteriores e posteriores estejam nos seus lugares.
¡Advertencia!
Las placas frontales y los paneles de relleno cumplen tres funciones importantes: evitan la exposición a niveles peligrosos de voltaje y corriente dentro del chasis; reducen la interferencia electromagnética (EMI) que podría perturbar la operación de otros equipos y dirigen el flujo de aire de enfriamiento a través del chasis. No haga funcionar el sistema a menos que todas las tarjetas, placas frontales, cubiertas frontales y cubiertas traseras estén en su lugar.
Varning!
Tomma framplattor och skyddspaneler har tre viktiga funktioner: de förhindrar att personer utsätts för farlig spänning och ström som finns inuti chassit; de innehåller elektromagnetisk interferens (EMI) som kan störa annan utrustning; och de styr riktningen på kylluftsflödet genom chassit. Använd inte systemet om inte alla kort, framplattor, fram- och bakskydd är på plats.
