I then put both aircons back on the 15A socket (circuit blue 11), using a 10A double-adapter. They were previously both on red 12 via different power points, and in particular gobi was plugged into the socket usually used for the light (which still needs a replacement tube). -- # TRS-80 trs80(a)ucc.gu.uwa.edu.au #/ "Otherwise Bub here will do \ # UCC Wheel Member http://trs80.ucc.asn.au/ #| what squirrels do best | [ "There's nobody getting rich writing ]| -- Collect and hide your | [ software that I know of" -- Bill Gates, 1980 ]\ nuts." -- Acid Reflux #231 / From mitch at ucc.gu.uwa.edu.au Mon Nov 2 23:37:38 2009 From: mitch at ucc.gu.uwa.edu.au (mitch at ucc.gu.uwa.edu.au) Date: Mon, 02 Nov 2009 23:37:38 +0800 Subject: [tech] Powering Off of Delta servers in rack closest to MR Door Message-ID: <20091102233738.15214qinqti929ds@secure.ucc.asn.au> Hi, If you have a server in the rack closest to the MR door can you please ensure its powered off by 6:30PM AWST Tuesday 3rd November as i will be unplugging it all to replace the power boards with proper power cables and plugs.

Canevas is designed for 12V, so I plugged in the 12V supply (which was lying next to the 19V supply - they have identical plugs). Perhaps unsurprisingly canevas now refuses to turn on. I have left it on the project bench, in hopes that someone with electronics skill feels like looking at it.

Most of the questions have simple yes/no answers although there is room to provide some explanation if necessary. [NTU] suggests that some of the questions raised (and some of our answers) would serve as a useful reminder for goals that we should be working towards in making a safer, friendlier machine room. Here is the checklist: Power --- A dedicated electrical power supply must be provided to the room. The power supply must be connected to an essential supply generator if provided. The room's power utilisation should be measurable The power supply must be sufficient for planned peak load, plus 25% The power supply must be fitted with surge protection, which may be provided by a UPS There must be a review of the need for UPS and/or generator backup, and those facilities provided where required All electrical equipment must be maintained as specified in the University Electrical Equipment Safety Policy Lighting --- The room must have sufficient lighting for visibility of the front and rear of racks and cabinets Lighting must be in accordance with AS/NZS 3084 ZB2.3.4.8 Fire --- The room must be protected by a centrally monitored fire alarm system. The room must have a CO2 type or vaporising liquid type fire extinguisher There must be a review of the need for additional fire suppression or fire detection equipment, and those facilities provided where required Environmental Management --- The room must have dedicated cooling, which may be a separate zone cooled by the central plant The room must have a redundant cooling system The cooling system must be able to maintain a room temperature of 18-27? C Relative humidity must be maintained within a range of 40-55% The room must have environmental monitoring of temperature and humidity, independent of building management system There must be a review of air movement and ventilation, and the room should be configured to cool equipment as efficiently as possible Dimensions and Location --- The room must be at least 15m2, with a minimum width of 3m. The clear height (i.e. without obstructions) must be at least 2.4m. The clearance in front of all cabinets and racks must be at least the width of the cabinet or rack door, plus 400mm. The clearance behind all cabinets and racks must be at least the width of the cabinet or rack door, plus 150mm. Where possible, clearance should be 1.0m or greater. The door to the equipment room must open outwards and be a minimum of 900mm wide and 2000mm high Entrance to the room must be secured, and egress must be possible without a key or tool. Where possible, the University campus card security system should be used. All doors to the room must open into secured locations, and not into public or external areas If the room has an external window, it must be blanked out No water pipes, water sprinklers, high voltage or power supply cables shall be installed within the equipment room or in areas that impact the room, except for those providing service to the room. No air ducts, except for ducts that provide service to the room, shall be installed or routed through the room. Selection of the room location should take into account security, access for delivery of goods, flood risk, and floor loadings. The room should be located away from sources of dust, vibration, EMI or RFI. Fittings --- The room must have anti-static flooring The room must have an operational telephone and GPO Racks must be properly grounded, in accordance with manufacturers instructions Where possible, only full-height racks should be installed, capable of holding full-size servers Where possible, the room should be fitted with a whiteboard Luke Williams UCC Wheel Member From nick at ucc.gu.uwa.edu.au Mon Nov 16 21:01:34 2009 From: nick at ucc.gu.uwa.edu.au (Nick Bannon) Date: Mon, 16 Nov 2009 21:01:34 +0800 Subject: [tech] [wheel] Fw: Server room specifications In-Reply-To: References: Message-ID: <20091116130134.GA12308@ucc.gu.uwa.edu.au> [LAW] got an email today via Wayne Howells, the Guild Finance Director.

This was likely caused by a Skype Supernode (http://en.wikipedia.org/wiki/Supernode_%28networking%29). Basically we have resolved this by setting a reasonable outbound Skype traffic limit for the RESNet Link. If you are seeing any other ongoing issues, please let contact the ITS Service Desk via http://its.uwa.edu.au/contact. Or feel free to ask questions via this RESNet mailing list.
