IBMDS470072A Controller

IBM DS4700 disk array controller coupler 9 into a new cabinet in the machine, removable sell 44X2425 44X2426 IBM DS4700 72A controller IBM4700 related presentation details, see "Installation, User's and Maintenance Guide" DS4700 size: 3U rack mount chassis ( IBM standard rack 19 inches), after wide: 44.70CM, front width: 48.26CM, long 57.15CM, high: 12.95CM. DS4700 Power requirements: Rated voltage: low (90 ~ 136V) high value (198 ~ 264V) Frequency: low (50 ~ 60HZ) a high value (50 ~ 60HZ) Current: low (4A / 4.54A) high value (2.12A / 2.41A) DS4700 Cooling: DS4700 rack ambient temperature should be maintained at about 22 degrees Celsius or less. Into the air from the front of the rack, from the back out, to prevent the flow of air out of the back of the rack into the entrance of another device, you must back side of the rack to the back and face alternately placed in rows. When the rack face to face or back to back arrangement, the gap is at least 1220MM, through the cold aisle (perforated floor) spaced rows. When the racks arranged in rows, each rack must be in contact with the adjacent racks may surround the back of the rack to reduce the inflow of hot air in the rack storage expansion enclosure entrance. DS4700 controllers: DS4700 has two redundant RAID controllers, left controller is labeled controller A, the default IP address of the Ethernet port on the controller A is: 192.168.128.101 and 192.168.129.101, subnet mask It is: 255.255.255.0. Controller mark on the right for the controller B, the default IP address for the Ethernet controller B: 192.168.128.102 and 192.168.129.102, Subnet Mask: 255.255.255.0 redundant dual-active RAID controllers (each control there is much to six Fibre Channel ports to connect the server and DS4000 storage expansion enclosures) but Fibre Channel ports differ depending on the model, 70 type 2, 72 type 4) DS4700 has up to 16 4GB Fibre Channel hard disk drives, which DS4700 insert itself up to 16 discs, at least before powering to insert two discs, or standard storage partition key might be lost. DS4700 can connect up to six storage expansion enclosures. DS4700 hot swappable, but swap interval of at least 1 minute, until the LED lights (green or yellow light) is not among sparkle again when. DS4700 dual power modules are connected to the two recommendations PDU. DS4700 installed in a rack on the bottom. DS4700 Indicators: LED display status of the storage subsystem and components. A green LED indicates normal operation. Amber LED (needs attention) indicate a possible fault. Blue LED CRU instructions on safely removing a component. LED lights on the front of the hard disk, (not flashing) - No processing data, Blinking - data is being processed. DS4700 power up: The two power switches on the back of the storage expansion enclosures are open, when powered, storage expansion enclosure on the front and back of the green and amber LED lights on and off intermittently. Open each controller north of DS4700 power switch, then the battery self-test takes 15 minutes, then the front and back of the LED flashes intermittently. Wait until the power-up is complete. When powered on, all LED front and back checking storage system, which is very important. During power up, when the storage subsystem and components complete the power-up procedure, LED indicator light flashes intermittently. In addition to checking for faults, you can use the storage subsystem front LED to determine if the drives are responding to IO transfer from the host. DS4700 power down: DS4700 power off the server; turn off the power DS4700; DS4700 expansion enclosures power shutdown; close optical switches, network switches power; DS4700 manage client connections: fitted with a Storage Manager Client client software PC or laptop via Ethernet Hub or Switch, DS4000 simultaneously connected to two controllers!
