Removing and Replacing Cold-Swappable Components |
Cold-swappable components require the system to be powered down before you can remove them.
In a Netra 440 server, the following components are cold-swappable:
The following section describes how to remove and install both the DVD-ROM drive and the DVD-RW drive (both referred to as the DVD drive in this section).
The part numbers for the DVD drives are:
2. Attach the antistatic wrist strap.
See Avoiding Electrostatic Discharge.
4. Press down on the two DVD drive locking tabs, releasing the DVD drive from its cage (FIGURE 4-1).
5. Pull out the DVD drive from the front of the system.
6. If you are not replacing the DVD drive immediately, install the DVD slot cover over the empty DVD space.
Insert the lower two tabs of the DVD cover into the two slots in the empty DVD space, then push the top of the DVD slot cover up until it clicks into place (FIGURE 4-2).
1. Remove the DVD slot cover, if one is installed.
Pull down on the top of the DVD slot cover, then lift it up and away from the empty DVD slot (FIGURE 4-3). Store the DVD slot cover in a safe place.
2. Slide the DVD drive into the system until the two DVD drive locking tabs click into place.
4. Power on the system and perform a configuration reboot.
The system configuration card stores system configuration variables and MAC addresses. For more information on the system configuration card, refer to the Netra 440 Server Product Overview (817-3881-xx).
You can replace a functioning system configuration card and install it into another system. thereby preserving the system's host ID information. Thus, migrating a system configuration card from one system to another can smooth transitions to new or upgraded systems, or quickly bring up a backup system if a primary system becomes unavailable, without disrupting the system's identity on the network. Note that you can only migrate a system configuration card from one Netra 440 server to another Netra 440 server.
If you are replacing a defective system configuration card, you must contact a Sun service representative to obtain a new card with the existing server's host ID and MAC address. Do not reuse an old system configuration card if you have replaced it with a new one with the same host ID and MAC address.
Keep the following points in mind when removing or installing the system configuration card:
|
Caution - Because the system configuration card is crucial for system operation, you must store the SCC safely if you have to remove it from the server, and replace it before restarting the server. |
For a list of OpenBoot configuration variables stored on the system configuration card, refer to the Netra 440 Server System Administration Guide (817-3884-xx).
The part number for the system configuration card is F370-5155.

The Netra 440 server uses 2.5-volt, high-capacity double data-rate dual inline memory modules (DDR DIMMs) with error-correcting code (ECC). The system supports DIMMs with 512-Mbyte and 1-Gbyte capacities.
Within each CPU/memory module, the four DIMM slots are organized into groups of two. The system reads from, or writes to, both DIMMs in a group simultaneously. DIMMs, therefore, must be added in pairs. The figure below shows the DIMM slots and DIMM groups on a Netra 440 server CPU/memory module. Adjacent slots belong to the same DIMM group. The two groups are designated 0 and 1.
You must physically remove a CPU/memory module from the system before you can install or remove DIMMs. The DIMMs must be added in pairs within the same DIMM group, and each pair used must have two identical DIMMs installed--that is, both DIMMs in each group must be from the same manufacturing vendor and must have the same capacity (for example, two 512-Mbyte DIMMs or two 1-Gbyte DIMMs).
|
Note - Each CPU/memory module must be populated with a minimum of two DIMMs, installed in either group 0 or group 1. |
|
Caution - DIMMs are made of electronic components that are extremely sensitive to static electricity. Static electricity from your clothes or work environment can destroy the DIMM. Do not remove a DIMM from its antistatic packaging until you are ready to install it on the CPU/memory module. Handle the DIMM only by its edges. Do not touch the components or any metal part. Always wear an antistatic grounding strap when you handle the DIMM. For more information, see Avoiding Electrostatic Discharge. |
You can maximize the system's memory bandwidth by taking advantage of its memory interleaving capabilities. The Netra 440 server supports two-way interleaving. In most cases, higher interleaving results in improved system performance. However, actual performance results can vary depending on the system application. Two-way interleaving occurs automatically in any DIMM bank where the DIMM capacities in DIMM group 1 do not match the capacities used in a DIMM group 2. For optimum performance, install identical DIMMs in all four slots in a CPU/memory module.
Keep the following points in mind when removing or installing a memory module:
|
Note - If DIMMs of different densities and speeds are installed as a pair, both DIMMs will operate at the lower density and slower speed. |
The part numbers for the memory modules are:
If a memory module (DIMM) fails, POST diagnostics alerts ALOM to light the enclosure status Service Required LED.
|
Caution - DIMMs are made of electronic components that are extremely sensitive to static electricity. Static electricity from your clothes or work environment can destroy the DIMM. Do not remove a DIMM from its antistatic packaging until you are ready to install it on the CPU/memory module. Handle the DIMM only by its edges. Do not touch the components or any metal part. Always wear an antistatic grounding strap when you handle the DIMM. For more information, see Avoiding Electrostatic Discharge. |
