Safety with Electricity


Warning    

Read the installation instructions before you connect the system to its power source.



Warning    

Ultimate disposal of this product should be handled according to all national laws and regulations.



Warning   

Only trained and qualified personnel should be allowed to install or replace this equipment.



Warning    

Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units.



Warning   

Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.



Warning   

Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.


Follow these guidelines when working on equipment powered by electricity:

Locate the emergency power-OFF switch in the room in which you are working. Then, if an electrical accident occurs, you can quickly shut the power OFF.

Disconnect all power before doing the following:

Installing or removing a chassis

Working near power supplies

Do not work alone if potentially hazardous conditions exist.

Never assume that power is disconnected from a circuit. Always check.

Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds.

If an electrical accident occurs, proceed as follows:

Use caution; do not become a victim yourself.

Turn OFF power to the system.

If possible, send another person to get medical aid. Otherwise, determine the condition of the victim and then call for help.

Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.


Caution   
For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohms (Mohm).

Cisco AS5300 Memory Systems

The Cisco AS5300 access server contains the following memory systems:

Two single in-line memory module (SIMM) sockets for main memory—Both must be filled, and they must contain equal memory sizes (16 and 16 MB, 32 and 32 MB, or 64 and 64 MB, yielding a total memory size of 32, 64, or 128 MB).

Main memory consists of dynamic random-access memory (DRAM) SIMMs. It is reserved for the CPU to execute Cisco IOS software and to hold the running configuration and routing tables.

One SIMM socket for shared (packet) memory (16 MB)

Shared memory also consists of DRAM SIMMs, and buffers data transmitted or received by the server's network interfaces.

Two SIMM sockets for system Flash memory, plus one for boot helper image (rxboot) Flash memory—One or both system Flash memory sockets may be filled. When both are filled, equal memory sizes are required (8 MB, 16 MB, 8 and 8 MB, or 16 and 16 MB).

Flash memory stores the Cisco IOS software image and the boot helper, a subset of Cisco IOS software that allows the server to boot when Flash memory does not contain a valid Cisco IOS image.

Because Flash memory holds the Cisco IOS image, replacing or upgrading it causes the image to be lost. To restore it, you need a Trivial File Transfer Protocol (TFTP) file server that holds the desired image. You can then download the Cisco IOS files into the upgraded Flash memory using TFTP. Consult your network administrator about the availability of TFTP file servers and Cisco IOS software on your network. Refer to the Cisco IOS configuration guides and command references for TFTP procedures.


Note   One upgraded server can function as a TFTP server to upgrade other servers.


The boot ROM is an erasable programmable read-only memory (EPROM) that stores the ROM monitor.

Nonvolatile random-access memory (NVRAM) stores the configuration file and virtual configuration register. This memory cannot be upgraded.

Required Tools and Equipment

This kit includes one of the following items:

New boot ROM

Appropriate DRAM SIMM(s)

Appropriate Flash memory SIMM(s)

To remove or install the boot ROM or the SIMMs, you will also need the following tools and equipment (which are not included):

Cisco AS5300 access server

Feature card removal tool

Medium-size Phillips screwdriver

ROM extraction tool or a small flat-blade screwdriver

ESD-preventive wrist strap

ESD-preventive mats

Removing the Chassis Cover

This section describes how gain access to the internal components by removing the chassis cover.


Warning   

Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.



Warning    

Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units.



Warning   

Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages.



Warning   

Do not work on the system or connect or disconnect cables during periods of lightning activity.


To remove the chassis cover:


Step 1 Turn the power switch on the access server OFF and disconnect site power. (Note that the power switch is part of the power supply.)

Step 2 Remove all interface cables from the rear panel of the access server.

Step 3 Place the access server so that the front panel is facing you.

Step 4 Remove the four screws on the chassis cover, as shown in .

Step 5 Lift the chassis cover upward as shown in , and pull it away from the tabs on the rear of the chassis.

Place the chassis cover in a safe place where it will not be damaged.

Removing Feature Cards

This section describes how to remove features cards. You must remove the feature cards to access the packet (shared) memory SIMM, one of the two main memory DRAM SIMMs, and the boot ROM. It is not necessary to remove the feature cards to access the Flash memory SIMMs.


Warning   

The E1 interface card may only be installed in an AUSTEL-permitted customer equipment or a data terminal equipment that is exempted from AUSTEL's cabinet, which has screw-down lids to stop user access to overvoltages on the customer equipment. The customer equipment has circuitry that may have telecommunications network voltages on them.



Caution   
The feature cards are not hot-swappable (that is, you cannot remove or install them when the power to the access server is ON). Be sure to turn OFF the power to the access server before installing or removing feature cards. Failure to do so can damage the access server.

To remove feature cards, refer to and take these steps:


Step 1 Turn the power switch on the access server OFF and disconnect site power.

Step 2 Attach an ESD-preventive wrist strap.

Step 3 Remove all interface cables from the rear panel of the access server.

Step 4 Loosen the two captive screws that secure the feature card to the chassis until each screw is free of the chassis.

Figure 3 Feature Card Removal (Carrier Card Shown)

Step 5 Insert the feature card removal tool so that the slots in each arm of the tool are behind the shoulder of each captive screw, as shown in , and carefully pull the removal tool toward you until the feature card slides free of the chassis.


Caution   
The EMI protective devices on the feature cards are designed to make the cards fit tightly. When removing the cards, they can release suddenly. Exercise caution when removing the feature cards with the removal tool.

Figure 4 Using the Feature Card Removal Tool

Step 6 Set the removed feature card aside on an ESD-preventive mat.

Replacing the Boot ROM

To upgrade the boot ROM software to a new software image, you must replace the existing boot ROM.


Warning   

Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units.



Warning   

Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.



Caution   
To avoid damaging ESD-sensitive components, observe all ESD precautions when handling SIMMs. To avoid damaging the motherboard or the SIMM, avoid excessive force when you remove or replace SIMMs.

To replace the boot ROM:


Step 1 Turn the power switch on the access server OFF and disconnect site power.

Step 2 Attach an ESD-preventive wrist strap.

Step 3 Remove the chassis cover. (See the instructions in "Removing the Chassis Cover" in this document.)

Step 4 Remove all feature cards to access the system card. (See the instructions in "Removing Feature Cards" in this document.)

Figure 5 System Card Layout

Step 6 Gently extract the old boot ROM with a ROM extraction tool or a small flat-blade screwdriver, and set the old boot ROM on a nonconductive surface.

Step 7 Insert the new boot ROM into the socket. Be careful not to bend or crush any of the bottom pins. If necessary, use needlenose pliers to straighten out any bent pins.


Caution   
The notch in the ROM must align with the notch in the socket on the system card. If the ROM is installed backwards, it will be damaged when the access server is powered ON.

Step 8 Replace any feature cards removed. (See the instructions in "Replacing Feature Cards" in this document.)

Step 9 Replace the access server chassis cover. (See the instructions in "Replacing the Chassis Cover" in this document.)

Step 10 Power ON the access server. If error messages relating to memory are displayed, remove the new boot ROM and reinstall it, taking care to seat the ROM firmly in its socket.

Replacing DRAM SIMMs

This section describes how to replace the DRAM SIMMs on the system card. You might need to replace the DRAM SIMMs for the following reasons:

You have upgraded to a new Cisco IOS feature set or release that requires more memory.

You are using very large routing tables or many protocols (for example, when the access server is set up as a connection device between large external networks and your internal network).

You are replacing a faulty SIMM.

The system card contains three sockets for DRAM SIMMs (see ):

Two sockets hold main memory DRAM SIMMs. Main memory is used by the CPU to store the operating configuration, routing tables, caches, and queues. The SIMMs can be 16, 32, or 64 MB, and the capacity of the SIMMs in both sockets must match. Therefore, the total main memory is 32, 64, or 128 MB.

One socket holds a shared (packet) memory DRAM SIMM. Packet memory is used to store incoming and outgoing packets. This SIMM can be 16 MB.


Warning    

Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units.



Warning   

 Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.



Caution   
To avoid damaging ESD-sensitive components, observe all ESD precautions when handling SIMMs. To avoid damaging the motherboard or the SIMM, avoid excessive force when you remove or replace SIMMs.

To replace the DRAM SIMMs:


Step 1 Turn the power switch on the access server OFF and disconnect site power.

Step 2 Attach an ESD-preventive wrist strap.

Step 3 Remove the chassis cover. (See the instructions in the section "Removing the Chassis Cover" earlier in this document.)

Step 4 Remove all feature cards to access the system card. (See the instructions in "Removing Feature Cards" in this document.)

Step 5 Use Figure 5 to locate the SIMM you are replacing.

Step 6 Pull the socket latches away from the SIMM, and then pull the SIMM out of the socket, as shown in Figure 6. The latches hold the SIMM tightly, so be careful not to break the latches.

Figure 6 Removing and Replacing the DRAM SIMM

Step 7 Position the new SIMM so that the polarization notch is located at the right end of the SIMM socket.

Step 8 Insert the new DRAM SIMM by sliding the end with the metal fingers into the SIMM socket at approximately a 45-degree angle to the system card, as shown in .

Figure 7 Inserting the New DRAM SIMM in the Socket

Step 9 Gently rotate the SIMM until the latches snap into place, Do not use excessive force because the socket might break.


Note   If upgrading to 128 MB (MEM-128M-AS53=), move jumper J3 from position 2-3 to position 1-2. shows jumper J3 in default position 2-3.


Step 10 Replace the feature cards. (See the instructions in "Replacing Feature Cards" in this document.)

Step 11 Replace the access server chassis cover. (See the instructions in "Replacing the Chassis Cover" in this document.)

Step 12 Power ON the access server. If error messages relating to memory are displayed, remove the DRAM SIMM and reinstall it, taking care to seat the SIMM firmly in its socket.

Replacing Flash Memory SIMMs

The system card contains three sockets for Flash memory SIMMs (see ):

Two sockets hold SIMMs containing the system software (Cisco IOS) image. Both of these SIMMs, labeled SIMM0 and SIMM1, must be installed. The SIMMs can be 8 or 16 MB, and the capacity of both SIMMs must match.

One socket holds a SIMM for the boot helper image (rxboot) software. This SIMM, labeled BOOT, must also be installed. The SIMM can be 8 or 16 MB.

Because Flash memory holds the Cisco IOS image, replacing or upgrading it causes the image to be lost. To restore it, you need a Trivial File Transfer Protocol (TFTP) file server that holds the desired image. You can then download the Cisco IOS files into the upgraded Flash memory using TFTP. Consult your network administrator about the availability of TFTP file servers and Cisco IOS software on your network. Refer to the Cisco IOS configuration guides and command references for TFTP procedures.


Note   One upgraded server can function as a TFTP server to upgrade other servers.


Flash memory SIMMs must be purchased from Cisco Systems, Inc. For ordering information, refer to the Information Packet that accompanied your access server.


Warning    

Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units.



Warning
