Overview

Rack system with horizontal ventilation

The PRIMECENTER M1 rack is ventilated from the front to the rear. A fully

configured rack in normal air-conditioned rooms can be operated at

temperatures up to 35°C. The volume of air required to cool the rack modules

is supplied via the integral horizontal ventilation system. The rack conforms to

protection class IP20 (i.e. protection against solid foreign bodies/without any

special protection against water; IP = International Protection). Honeycomb-

shaped holes in the doors (up to 80% holes) enable uniform, passive ventilation.

Hard disk expansion / Extension for tape drives

Fujitsu offers a large portfolio of storage subsystems to expand the hard disk

capacity as well as for data backup.

Automatic console switching

The administration of several servers can be performed as an option via the rack

console by means of console switches. Console switches are offered with 4, 8,

16 and 32 channels. Switching over is carried out by means of hotkeys or the

OSD (on screen display) function. Digital KVM (Keyboard-/Video-/Mouse-)

switches can be used to integrate rack systems in a LAN and administered

worldwide.

UPS systems

The availability of the systems can be increased through the use of optional

UPS (interruptible power supply) modules. These provide the systems with

adequate protection against power outages and fluctuations in the line voltage.

Depending on configuration within the rack, a number of systems can be

protected by a single UPS. APC modules rated at 1,500 VA, 3,000 VA and 5,000

VA, and online UPS rated 3 / 5 KVA and 8 / 10 / 20 KVA are currently available.

All UPS modules are equipped with an SNMP interface (signal line). All the

parameters and statuses of the installed UPSs can thus be set and monitored

with the server management. A power failure can be automatically reported to

every connected server by means of traps.

Ease of serviceability and maintenance

The rack servers and expansion modules, which are mounted on telescopic or

sliding rails, can be installed in a rack without the need for any tools. If telescopic

rails are used, systems can be withdrawn toward the front. This facilitates

maintenance and upgrade operations by allowing technicians access to all the
