This chapter gives the procedures for connecting the SCSI Expansion Pedestal to a SPARCserver 670MP.
Follow these steps to prepare the system for cabling:
Figure 6-1 Release Latch Location
The DC power switch is located behind the front panel (see Figure 6-2).
The AC power switch is located at the rear of the pedestal next to the power receptacle (see Figure 6-3).
Note - Systems shipped inside the US and Canada have an AC power cord with a three-slot female plug at one end and a three-pronged male plug at the other end. Systems shipped outside of the continental US may have different power cords shipped in a separate kit. See the instructions provided with the kit for details.
The power cord provides a ground path which will keep the drives and boards installed in your unit from being damaged from static electricity.
Figure 6-4 Release Knob Location
The DC power switch is located behind the front panel (see Figure 6-5).
The AC power switch is located at the rear of the pedestal next to the power receptacle (see Figure 6-6).
If the power switches on the SPARCserver 670MP are not in the OFF positions, refer to the SPARCsystem 670MP Installation Manual (P/N 800- 5904-xx) for instructions on powering down the unit before proceeding.
If the power cord for your SPARCserver 670MP is not plugged into a grounded wall outlet, plug the three-slot female end of the AC power cord in the AC receptacle at the rear of the pedestal. The AC receptacle is located next to the AC power switch.
Plug the other end of the AC power cord into a grounded wall outlet. The power cord provides a ground path which will keep the drives and boards installed in your unit from being damaged from static electricity.
Before you can connect your SCSI Expansion Pedestal to your SPARCserver 670MP, you must first determine which trays inside your SCSI Expansion Pedestal contain SCSI devices, since these are the only trays you will have to connect to your SPARCserver 670MP. You can determine which trays contain SCSI devices by the pedestal configuration you ordered from Sun Microsystems (see Table 6-1).
For example, if you ordered the marketing numbers X762AR6 and X763AR6, the bottom and middle SCSI trays contain SCSI devices for your configuration.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Once you have determined which trays contain SCSI devices in your pedestal, you must verify that you have the proper number of SCSI host adaptor cards installed in the SBus slots in your SPARCserver 670MP. Examples of SCSI host adaptor cards would be FSBE/S cards for the SunCD, tape drives or 1.3 Gbyte disk drives, and DSBE/S cards for the 2.1 Gbyte disk drive.
The following list shows the total number of SCSI host adaptor cards you must have installed in the SPARCserver 670MP for each tray in your pedestal:
Note - The top tray of the pedestal will be connected to the bottom tray of the pedestal, so a SCSI host adaptor card is not needed for the top tray.
In other words, if you have SCSI devices in the bottom and middle trays of the first SCSI Expansion Pedestal, you should have two SCSI host adaptor cards installed in your SPARCserver 670MP - the first SCSI host adaptor card for the bottom tray, and the second SCSI host adaptor card for the middle tray.
The SCSI host adaptor cards should be installed beginning at SBus slot 0 in your system, so if the SBus 0 slot is free, you would install the first SCSI host adaptor card in SBus slot 0, the second SCSI host adaptor card in SBus slot 1, and so on (likewise, if the SBus slot 1 is the first available SBus slot, you would install the first SCSI host adaptor card in SBus slot 1, the second SCSI host adaptor card in SBus slot 2, and so on). Figure 6-7 shows the location of the SBus slots on the SPARCserver 670MP.
If you do not have the proper number of SCSI host adaptor card installed in your SPARCserver 670MP, you can order one through Sun Microsystems. Refer to the manual you received with the card for installation instructions.
You are now ready to connect the tray(s) to your SPARCserver 670MP. Turn to the appropriate section for the cabling instructions for each tray:
Follow these instructions to connect the bottom tray of your SCSI Expansion Pedestal to a SCSI host adaptor card installed in your SPARCserver 670MP:
Figure 6-8 shows the location of the ports on the bottom tray in the SCSI Expansion Pedestal. Either port can be used as the "SCSI IN" port, so plug the cable into the port that is most convenient for you.
If the bottom tray contains differential SCSI disk drives (such as the 2.1 Gbyte disk drive), turn the jackscrews on both sides of the connector clockwise to secure the cable to the tray.
If the bottom tray contains differential SCSI disk drives (such as the 2.1 Gbyte disk drive), turn the jackscrews on both sides of the terminator clockwise to secure the terminator to the tray.
Figure 6-9 shows the proper connection if the first SCSI host adaptor card is installed in the SBus 0 slot and the third SCSI host adaptor card is installed in the SBus 2 slot.
Figure 6-9 Connection for the Bottom SCSI Tray
The procedure for connecting the bottom tray of your SCSI Expansion Pedestal to your SPARCserver 670MP is now complete.
Note - Do not connect a separate SCSI device between your pedestal and your SPARCserver 670MP, since this could result in a conflict in SCSI addressing.
If you have SCSI devices in another tray in your SCSI Expansion Pedestal, refer to the appropriate section for instructions on connecting that tray:
If you have no other trays to connect, refer to Section 6.3, "What's Next."
Follow these instructions to connect the middle tray of your SCSI Expansion Pedestal to a SCSI host adaptor card installed in your SPARCserver 670MP:
Figure 6-10 shows the location of the ports on the middle tray in the SCSI Expansion Pedestal. Either port can be used as the "SCSI IN" port, so plug the cable into the port that is most convenient for you.
If the middle tray contains differential SCSI disk drives (such as the 2.1 Gbyte disk drive), turn the jackscrews on both sides of the connector clockwise to secure the cable to the tray.
If the middle tray contains differential SCSI disk drives (such as the 2.1 Gbyte disk drive), turn the jackscrews on both sides of the terminator clockwise to secure the terminator to the tray.
Figure 6-11 shows the proper connection if the second SCSI host adaptor card is installed in the SBus 1 slot and the fourth SCSI host adaptor card is installed in the SBus 3 slot.
Figure 6-11 Connection for the Middle SCSI Tray
The procedure for connecting the middle tray of your SCSI Expansion Pedestal to your SPARCserver 670MP is now complete.
Note - Do not connect a separate SCSI device between your SCSI Expansion Pedestal and your SPARCserver 670MP, since this could result in a conflict in SCSI addressing.
If you have SCSI devices in another tray in your SCSI Expansion Pedestal, refer to the appropriate section for the instructions on connecting that tray:
If you have no other trays to connect, refer to Section 6.3, "What's Next."
The procedure for connecting the top tray to a SPARCserver 670MP will vary depending on the type of disk drives you have installed in the middle or bottom trays in the SCSI Expansion Pedestal.
Follow these instructions to connect the top tray of your SCSI Expansion Pedestal to your SPARCserver 670MP if you have single-ended SCSI disk drives installed in the middle or bottom trays of the SCSI Expansion Pedestal:
Refer to Table 6-1 for help in determining which disk tray is single-ended SCSI.
Figure 6-12 shows the location of the ports on the top tray in the pedestal.
For the top tray, use the single-ended SCSI terminator (P/N 150-1785).
Figure 6-13 shows the proper connection if the bottom tray is a single-ended SCSI drive tray.
Figure 6-13 Connection for the Top SCSI Tray
The procedure for connecting the top tray of your SCSI Expansion Pedestal to your SPARCserver 670MP is now complete.
Note - Do not connect a separate SCSI device between your SCSI Expansion Pedestal and your SPARCserver 670MP, since this could result in a conflict in SCSI addressing.
If you have SCSI devices in another tray in your SCSI Expansion Pedestal, refer to the appropriate section for the instructions on connecting that tray:
If you have no other trays to connect, refer to Section 6.3, "What's Next."
If you have differential SCSI disk drives installed in both the middle and bottom trays of the SCSI Expansion Pedestal or you have differential SCSI disk drives installed in the bottom tray and no middle tray installed, you can connect the top tray to the SPARCserver 670MP using one of two methods:
---------------------------------------------------
SCSI Device SCSI Address ---------------------------------------------------
First SunCD 6
Second SunCD 1
Third SunCD 5
Fourth SunCD 0
First 150 Mbyte 1/4-Inch Tape Drive 1
Second 150 Mbyte 1/4-Inch Tape Drive 5
Third 150 Mbyte 1/4-Inch Tape Drive 0
2.3 or 5.0 Gbyte 8 mm Tape Drive 5
First 1.3 Gbyte Disk Drive 3
Second 1.3 Gbyte Disk Drive 2
Third 1.3 Gbyte Disk Drive 5
---------------------------------------------------

Second 5.0 Gbyte 8 mm Tape Drive 5
-----------------------------------------------
If you find that you have two devices with the same SCSI address, you must plug the top tray of the SCSI Expansion Pedestal into a separate SCSI bus.
Follow these instructions to connect the top tray of your SCSI Expansion Pedestal to your SPARCserver 670MP:
Figure 6-14 shows the location of the ports on the top tray in the SCSI Expansion Pedestal. Either port can be used as the "SCSI IN" port, so plug the cable into the port that is most convenient for you.
For the top tray, use the single-ended SCSI terminator (P/N 150-1785).
Figure 6-15 shows the location of the SBus slots and the on-board SCSI port on the SPARCserver 670MP.
The procedure for connecting the top tray of your SCSI Expansion Pedestal to your SPARCserver 670MP is now complete.
Note - Do not connect a separate SCSI device between your SCSI Expansion Pedestal and your SPARCserver 670MP, since this could result in a conflict in SCSI addressing.
If you have SCSI devices in another tray in your SCSI Expansion Pedestal, refer to the appropriate section for the instructions on connecting that tray:
If you have no other trays to connect, refer to Section 6.3, "What's Next."
You have connected all the trays that contain SCSI devices in your SCSI Expansion Pedestal to your SPARCserver 670MP. Figure 6-16 shows how a typical system may look with all the SCSI trays in two SCSI Expansion Pedestals connected to a SPARCserver 670MP.
Figure 6-16 Connection for All the SCSI Trays
You should now route the cables through the cable clamps located along both sides of the inside rear bezel of the SCSI Expansion Pedestal. These cable clamps are used to restrain the cables.
Follow these steps to route the cables through the cable clamps:
The cable clamps should be installed along both sides of the inside rear bezel of your SCSI Expansion Pedestal. The cable clamp you will use varies depending on which tray the cable is connected to.
If you are securing a cable coming out from the bottom tray, use the middle cable clamp located along the inner bezel that is closest to the cable. Figure 6-17 shows how you would secure a cable that is connected to the bottom right SCSI port - securing a cable on the opposite side of the pedestal would be the same.
Figure 6-17 Securing a Cable from the Bottom Tray
If you are securing a cable coming out from the middle tray, use the bottom cable clamp located along the inner bezel that is closest to the cable. Figure 6-18 shows how you would secure a cable that is connected to the middle right SCSI port - securing a cable on the opposite side of the pedestal would be the same.
Figure 6-18 Securing a Cable from the Middle Tray
If you are securing a cable coming out from the top tray, use the top and bottom cable clamps located along the inner bezel that is closest to the cable. Figure 6-19 shows how you would secure a cable that is connected to the top left and bottom left SCSI ports - securing a cable on the opposite side of the pedestal would be the same.
Figure 6-19 Securing a Cable from the Top Tray
Note - Make sure the connector is level with the floor when routing the cable through the clamp. If the connector is bent too far up or down, release the cable from the clamp and take up or let out the slack in the cable until the connector is level, then clamp the cable again.
Refer to Chapter 7 next, "Powering the System On and Off," for instructions on powering on the system.
