Open Case
1.  Remove the front cover: 
    a. Unlock the cover.  (If you have a key, you are unique) 
    b. Grasp cover at bottom and firmly pull it away from server. 
    c. Remove the top corners of the cover from the server. 
 NOTE: Do NOT twist the bezel to one side!. The pivot points WILL snap if you apply too much crosswise force. 
 

2.  Remove the side cover: 

    a. Pivot side cover away from the front of the server. 
    b. Pull the cover forward. 
    c. Place cover so as to protect the fan from possible damage. 
 NOTE: The EMC bezel in the front right corner (shiny metal springs) is quite sharp if you pull up or down on this edge of the case. Hint, Hint... 

 3.. Remove the drive retainer: (Only to install/remove drives) 

    a. Press down on both top latches. 
    b. Pull the top of the retainer out from the server. 
    c. Pull the retainer up. 

 Now you do whatever you were going to do inside the case... 
 
 
 

Close Case 

 1.  Install the drive retainer:  (Only if you removed it previously) 

   a. Insert tabs on drive retainer into groove at bottom of server. 
   b. Pivot retainer into position.
   c. Push retainer until it clicks into place. 
 NOTE: You may have to "play" with the drive retainer. Try pulling it up a little and wiggle it while pivoting it into position. 
 

 2. Replace the side cover: 

 

       a. Align rear of side cover with the groove at rear of frame.
       b. Align top edge of side cover over top of frame. 
       c. Push side cover closed. 
 
 
 
 

 NOTE: If you have one hand on the top of the case with fingers inside the case, do NOT attempt to close the side cover. #1, it won't work, and #2, you will need Band-Aids for the flesh wounds.
     Note:  Do not damage the hardware around side cover fan when installing the covers.

 3.  Replace the front cover: 

       a. Slide top posts into the holes at the top of the server. You may have to press the side
 cover closed if the old flat SCSI cable is used. Be cautious - if the side cover won't easily close, check your cable routing. A problem area is towards the front of the complex and behind the DASD Support Structure. 
NOTE: Do not accept the prongs on the front cover going in the mounting holes at an angle!
NOTE: The front cover MUST fit over the front edge of the side cover!

b. IF front cover swings ON IT'S PIVOTS over front edge of side wall cover, smack the front cover bottom, one corner at a time, until it snaps into place. 
     If front cover does not snap into place 
       Is it able to fit over the front edge of the side cover?
       Make sure the drive retainer has been installed correctly. 
      Are all indexing posts on front bezels aligned with the holes in the DASD Support Structure?
      On a 95A or 85 K/N system, the LogicLock switch on the drive retainer may not be firmly
 seated, and has been partially knocked off. Reseat the switch. (white plastic box, about that of a
 small matchbox). 

       c. Lock the front cover. 
          Note:  If you ever enable the LogicLock on a 95A or 85 K-N and move your system, be
 sure not to jar or pull on the front cover. Security features on the cover will respond as if someone is trying to break into your server, giving you an error message. 
 NOTE: If you enable the unauthorized access feature on a 95A or 85 K-N and you forget the
 password, you will be unable to run system programs ever again with that planar. Do NOT enable the unauthorized access feature unless you REALLY, REALLY need it. You had better have a key for the bezel lock also. These systems are C2 rated. 

Ventilation Requirements 

 

   Warning: Be sure to maintain a clearance of at least 51 mm (2 in.) on all sides of the server to
 allow for air circulation. 
 
 
 
 
 
 
 
 
 



Install Memory on 85 or 95
   1.  CAUTION: When you tilt out the power supply, do not let it drop.  Personal injury or
 damage to the server might result. 

 

 Tilt out the power supply: 
       a. Disconnect drive power cables from the power supply. 
       b. Unscrew the blue spring-loaded retaining knob until it releases. 
       c. Place one hand on top of the server to support it. 
       d. Tilt out PSU with the other hand. (Be sure the AC power cord is removed from the server
 before you try to tilt out the power  supply.) 
 
 

 2.  Install SIMMs in pairs of the same size, speed, and type. All memory must be of the same type (parity OR ECC). Install SIMMs in the following order: A1-B1, A2-B2, A3-B3, A4-B4. 
A and B Bank Layouts
 A and B Bank Layouts 

   3.  Touch any unpainted metal surface on the server.  This equalizes the voltage potential between you and the system. Remove the SIMM from anti-stat package (if applicable) and place it into the SIMM socket WITH THE NOTCH UP. Push the SIMM in and slowly rotate it to the right untill it snaps into place.

SIMM Orientation 

 4.  Reinstall the power supply: 
       Move the power and SCSI cables out of the way. 
 NOTE! If you have a SCSI CD rom with an external terminator on it in the single 5.25" bay, this
 is referred to as a "guillotine"! Push the CD Rom drive forward, then hold the SCSI cable towards the front of the case while rotating the power supply back in. Or you WILL be sorry... 
       Tilt the power supply into the server. Press in the retaining knob and turn it to the right until it is tight. NOTE! Do NOT tighten the blue knob more than finger tight! Otherwise the e-clip will be deformed and it will fall off... More details HERE  Reconnect the twisted power cables to the power supply. 



Early 95s without Shutter over Power Switch
> Early 8595 have no clear springy cover over the power switch. It's kinda funky looking having a beige "ring" around the white switch.

Tony Ingenoso replies:
   These are the earliest models - undoubtedly a T1.  That "feature" was rectified fairly quickly when the complaints rolled in from the field. People who had 'em on the floor were turning them off by mistake thinking they were reaching for the FDD eject button.  This is one of the few truly
lame things about the 95 -- because the test labs were complaining about the same thing fairly early on.



Mounting Hardware

 Drives come in a variety of heights. You can install half-high drives that are less than 41.3 mm (1.6 in.) high in any of the bays.  Drives that are greater than 41.3 mm (1.6 in.) high (full-high) can be installed in bay C or bay D. Bays C and D can each hold two half-high drives or one full-high drive. 

Slide - Mount floppy drive sized devices in Bays A and B (floppy, tape, or PCMCIA)
Tray - Mount 3.5" drives in the 5.25" drive bays.
   NOTE: You will need Rail Guides in the DASD Support Structure!
Rails - Mount 5.25" drives (floppy, CD, HD)

          Cover plates (sometimes called bezels) cover the front of each installed drive. If you install a drive that uses removable media (diskette, tape, optical disc, or CD), you will need to change the cover plate. 



Installing Floppy Drives

Install the diskette drive in bay A or B: 
Note:  The figures that accompany these steps show the installation occurring in bay A.  These instructions also apply to bay B. 
   a. If a flat cable is folded inside bay A, unfold it and route it along the back of the bays. 
   b. Position the drive so the connector is facing the rear of the server. 
   c. Align the drive with the guides on the bottom of the bay. 
   d. Slide the drive into the bay until it stops. 


3.  Locate the connector on the flat cable directly behind the bay you are using (A or B), and connect it to the back of the drive. 
Note:  For bay A, use the middle connector (labeled "P2-1"). For bay B, use the bottom connector (labeled "P2-0").  FWIW, P2-2 is for a floppy tape backup OR for a 5.25" floppy.

Remove Rail Guide From Storage Tray

Pull up on the tab (1) on the back of the tray and pull out the rail guides stored on the bottom of the tray.

Insert Rail Guide


Press a rail guide into each side of the DASD support structure. The left and right guide rails are the same.



5.25" Drive Rail Dimensions

  I measured this from a single RAID bay.



HD Mounting Tray

 

85 P/N 85F0013
95 P/N 64F0141

My 9595s are stamped 10G4769.

NOTE: The drive may be installed in the tray with the mounting screw flange pointed down (as pictured)  or pointed up. This is helpful if you have a mix of 1.6" and 1" drives to install.
