At the moment, we are in the middle of a small heat-wave here. The past few days were all above 30 deg C. While that may be quit usual for you guys in sunny California or other nice parts of the world, here it is rather exceptional. And, much to our regret, we don't have airco at the University. Last week, when the temperature was on its maximum in the computer room, one of our SUN shoeboxes started showing a lot of hard data errors. A reformat didn't help. The SUN field engineer quickly recognized the problem as overheating of the shoebox, caused by dusty blower grids. The problem is this. Each blower is protected by a rather fine mesh on the outside, to prevent you from putting your fingers in the fan. This mesh is so fine that is collects a lot of dust, blocking the airflow. And without sufficient airflow, it can become pretty warm inside... Cleaning the mesh solved the problem. Alarmed by this phenomenon, I had a look at the blowers of my shoebox at home. Eh... well... You see, at the University the rooms are cleaned every day, but at home...:-) Cleaning the shoebox was like emptying the vacuum-cleaner. To be safe, I removed those mesh filters. After all, there are still those other grids protecting the blowers. The mesh filters are spotwelded, so it is a destructive operation, but when you do it carefully, you can replace them if you wish. This removal does not seem to affect the noise level. So, when you don't live in a Clean Room, have a look at the blowers of your shoebox at home once in a while, or remove those mesh filters. It can prevent disasters. Pieter --- Pieter H.A.

(who is the publisher of the latter and how can i subscribe?) are there more of interest? thanx in advance... labtg@emoryu1.cc.emory.edu tom genese, UWIT bitnet: labtg@emoryu1.bitnet irc: integral math/cs dept. cis: 74476.1471@compuserve.com emory university uucp:{sun!sunatl,gatech}!emoryu1!labtg atlanta, ga, usa ------------------------------ Date: 31 Jul 90 09:22:12 EDT (Tue) From: wolves.uucp!biggers@mcnc.org Subject: want info on disk/tape shoeboxes for Sun-4 To: orchestra.ecn.purdue.edu!suns-at-home@mcnc.org Hello, I recently acquired a Sun 4/110 FCE (what does FCE stand for, anyway :^) for home business use, and am now scouting out reasonably priced disk/tape shoeboxes (600mb SCSI disk, 150 mb tape). Some friends who have MacIIs running A/UX have pointed me to the great deals on shoeboxes for Macs; configurations like what I want are running about $2900 or so. HOWEVER, these generic boxes work fine for a MacII, but I've read that the Sun-4 is NOT a completely conforming SCSI implementation. So, where did you all get your shoebox from? The prices I'm being quoted from Sun-compatible disk sellers are around $3300 to $3400 for a shoebox, including Sun-4 cables. Any recommendations are appreciated (as to seller, your favorite disk -- Fujitsu, CDC, HP -- or whatever). I'd rather be safe than sorry at these prices... thanks much, mark Mark Biggers Domain: biggers%wolves@cs.duke.edu UUCP: ...!mcnc!wolves!biggers [ You might try UNINET (send, "send VENDOR disks.uninet" to the SaH archive ] [ server.).
