Upgrading Processors
Each of the server platforms requires the user of 440 MHz processors. The number of 440 MHz processors required in each server platform is as follows:
•Netra t 100/105—1
•Netra t 1120/1125—2
•Netra t 1400/1405—4
Depending on the number and speed of the processors in your host, you might have to replace your processor or add additional processors. The following sections contain procedures that describe how to remove and replace or add processors:
• Installing 440 MHz Processors
• Removing a CPU Module
• Replacing a CPU Module
Note The CPU in the Netra t 100/105 cannot be upgraded.
Caution You must use processors of identical speed; you cannot mix processors of different speeds.
Installing 440 MHz Processors
To install 440 MHz processors, follow the documentation that shipped with your processors. Typically the following documents are included:
•SunTM 450 MHz UltraSPARCTM-ii Module Upgrade, p/n 806-1055-11
•SunTM Flash PROM Guide for Workstations and Workgroup Servers—Standalone Version,
p/n 802-3233-19
Note If you are using OpenBoot PROM version 3.17.0 or later, you do not need to update the Flash PROM. Set the buffer speed on the motherboard by changing the clocking select jumper J3001 as shown in Figure 5-2.

Upgrading Memory
The minimum amount of memory required in each server platform is as follows:
•Netra t 100/105—1 gigabyte
•Netra t 1120/1125—2 gigabytes
•Netra t 1400/1405—4 gigabytes
If you do not have enough memory, you must add additional memory modules of the following types:
•Netra t 100/105—Memory board
•Netra t 1120/1125—Single in-line memory modules (SIMMs)
•Netra t 1400/1405—double in-line memory modules (DIMMs)
The following sections contain procedures that describe how add additional memory:
• Removing a Memory Module
• Replacing a Memory Module
Caution Memory modules consist of electronic components that are extremely sensitive to static electricity. Ordinary amounts of static electricity from clothing or work environment can destroy the memory module.
Caution When removing a SIMM or DIMM, an identical replacement is required. The replacement SIMM or DIMM must be inserted into the same socket as the removed memory module.
Caution Each SIMM or DIMM bank must contain at least two SIMMs or DIMMs of equal density (for example, two 32-megabyte SIMMs) to function properly. Do not mix SIMM or DIMM densities in any bank.
Tip The system unit must have at least two identical SIMMs or DIMMs installed in paired sockets of any SIMM or DIMM bank. For best system performance, install four identical SIMMs or DIMMs.

• Removing a SIMM from a Netra t 1120/1125 Chassis
• Removing a DIMM from a Netra t 1400/1405 Chassis
Caution Use proper ESD grounding techniques when handling components. Wear an antistatic wrist strap and use an ESD-protected mat. Store ESD-sensitive components in antistatic bags before placing them on any surface.
Replacing a Memory Board in a Netra t 100/105 Chassis
There is only one installation location for memory in the Netra t 100/105s. There are three sizes of memory available:
•64 Mbyte memory board (part number 595-5314)
•256 Mbyte memory board (part number 370-4155)
•512 Mbyte memory board (part number 595-5316)
Note Do not install memory boards in a stack of three. These boards can only be installed singly or in twos. The 256 Mbyte board is the only board that can be installed in a stack of four.
Perform the following steps to replace a memory board in a Netra t 100/105 chassis:
Step 1 Ensure the wrist strap is still attached and the system is powered off.
Step 2 Position the new spacers over the screw holes.
Step 3 Insert the new, longer screws with their washers through the holes in the new board. Place the spring washer on the screws first, and then the plain washer.
Step 4 Position the secondary memory board above the base memory board so that the connectors line up and the screws pass through the spacers.
Step 5 Engage the screws in their threads to ensure that the board is in the correct position.
Step 6 Press down firmly on all three memory board connectors until they are firmly seated in the connectors on the board beneath. You might find it helpful to seat the middle connector properly before the other two connectors. You will feel a slight click as the connectors engage.
Caution Although it is necessary for the connectors to be properly seated, you must not apply excessive pressure to them. If you do, you might cause micro-fractures on the motherboard which can impair the operation of the board.
Step 7 Tighten the securing screws so that the boards sit firmly on the motherboard.
Step 8 Replace the processor cover located in the rear center of the unit. Make sure you put the tabs of the processor cover back into their original position underneath the rear I/O card.
Step 9 Plug in the serial and SCSI cables to the rear I/O board.
Step 10 Slide the cover forward to close the chassis, and tighten the cover screw using a Phillips No. 2 screwdriver.
Step 11 Replace the rack brackets, if fitted previously.
Step 12 Detach the antistatic wrist strap.
Step 13 Reconnect the input power connectors and power on the system. See the "Installing a Hard Disk Drive in a Netra t 1400/1405 Chassis" section for instructions.

Step 1 Ensure the wrist strap is still attached and the system is powered off.
Step 2 Locate the appropriate SIMM slots on the motherboard.
Note The system unit must have at least two identical SIMMs installed in paired sockets of any SIMM bank. For best system performance, install four identical SIMMs. Table 5-1 identifies SIMM installation locations.
Caution Hold SIMMs only by the edges.
Step 3 Remove the SIMM from the antistatic container.
Step 4 Position the SIMM in the socket, ensuring that the notch is on the same side as the lever.
Step 5 Using your thumbs, press firmly on the top of the SIMM until it is properly seated.
Caution Do not use excessive force; the lever can snap. Apply even, lateral pressure to the lever when seating the SIMM. Make sure the SIMM is level when pushing it into the socket.
Note Proper SIMM seating is verified by a clicking sound. Ensure the SIMM is properly seated.
Step 6 Replace the power supply:

Perform the following steps to replace a DIMM in a Netra t 1400/1405 chassis:
Step 1 Ensure the wrist strap is still attached and the system is powered off.
Step 2 Locate the appropriate DIMM slots on the motherboard.
Note The system unit must have at least two identical DIMMs installed in paired sockets of any DIMM bank. For best system performance, install four identical DIMMs. Table 5-2 identifies DIMM installation locations.
Caution Hold DIMMs only by the edges.
Step 3 Remove the DIMM from the antistatic container.
Step 4 Position the DIMM in the socket, ensuring that the notch is on the same side as the lever.
Step 5 Using your thumbs, press firmly on the top of the DIMM until it is properly seated.
Note Proper DIMM seating is verified by a clicking sound. Ensure the DIMM is properly seated.
Step 6 Replace the top access cover. See the "Removing a CPU Module from a Netra t 1400/1405 Chassis" section.
Step 7 Detach the antistatic wrist strap.
Step 8 Reconnect the input power connectors and power on the system. See the "Installing a Hard Disk Drive in a Netra t 1400/1405 Chassis" section for instructions.
Verifying The Hardware Installation
After installing new hardware components, you can run a diagnostic program to ensure the system recognizes your components.
To run the diagnostic program:
Step 1 Start at the ok prompt and enter:
setenv auto-boot? false
setenv diag-switch? true
This disables automatic booting and runs a diagnostic program.
Step 2 Unplug the network Ethernet cable from the machine.
Details about the system components, including hard drives, memory, and processors, appear on the screen. If you do not see the components you recently installed, you must perform troubleshooting steps to determine the problem. Contact the Cisco TAC for assistance in troubleshooting. See the "Obtaining Technical Assistance" section on page xviii for more information.
Step 3 The machine eventually stops trying to boot from the network and returns to the ok prompt. Enter the following commands:
setenv auto-boot? true
setenv diag-switch? false
Step 4 Reboot the machine.
Where to Go Next
This completes upgrading your hardware. Return to the appropriate upgrade procedure for your solution for the next step in your upgrade.
