4.7 Rails and Cable Management
ReadyRails
TM
Sliding Rails for 4-post racks support the following:
 Toolless installation in 19” EIA-310-E compliant square or unthreaded round hole 4-post racks
including all generations of Dell racks. (Note: Threaded 4-post racks require Dell’s fixed shelf
or third-party adapter brackets available through Dell Software & Peripherals.)
 Full extension of the system out of the rack to allow serviceability of key internal components
 Optional cable management arm (CMA) except on racks less than 1m in depth including Dell
4200 and 2400 racks.
Measurements and adjustment ranges for the rack:
 Rail depth without the CMA: 755 mm
 Rail depth with the CMA: 883 mm
 Square-hole rack adjustment range: 686–883 mm
 Round-hole rack adjustment range: 672–876 mm
See Section 14, Rack Information, for more information.
4.8 Fans
Six 120mm single-rotor hot-pluggable fans are mounted in a fan bay in the back of the chassis. Each
fan has a single wire harness that plugs into the planar fan connectors (FAN1 through FAN6).
The Embedded Server Management (ESM) logic in the system controls and monitors the speed of the
fans. A fan speed fault or over-temperature condition results in a notification by ESM.
The R910 power supply units have integrated fans. The system requires a blank in place of the empty
power supply slot. System fan speed is pulse-width modulated.
The iDRAC6 controls and monitors the speed of the fans. A fan speed fault or over-temperature
condition results in a notification by iDRAC6.
4.9 Security
4.9.1 Cover Latch
A tooled latch is integrated in the side cover to secure it to the tower chassis. A locked bezel secures
the cover latch.
4.9.2 Bezel
A lock on the bezel is used to protect unauthorized access to system hard drives and the system
cover. System status (through the LCD) is viewable when the bezel is installed.
4.9.3 Hard Drive
The front bezel of the system contains a lock. A locked bezel secures the system hard drives.
4.9.4 Trusted Platform Module (TPM)
TPM is used to generate/store keys, protect/authenticate passwords, and create/store digital
certificates. TPM can also be used to enable the BitLocker™ hard drive encryption feature in Windows
Server 2008.
