enhanced serviceability
The following is a list of rp8400 enhanced serviceability features:
• hot-plug functionality for internal disks, PCI cards, removable-media drives (also, hot-plug cell
boards will be enabled with a future release of HP-UX)
• hot-swap functionality for bulk power supplies and cooling fans
• product length from mounting column to the connector-mating surface at rear of 26.75 inches
(~30 inches overall with the front bezel sitting forward of the rack column), leaving four inches
for cable bending in third-party racks
• PCI card access from the top of the chassis so that ceiling light enhances visibility
• access panels as large as possible to enhance the service access area
• five-sided access to maximize accessibility
• independent access to major FRUs; any FRU can be accessed and removed within 15 minutes
or less
• access to most commonly serviced components from the front or rear without moving the
package in the rack
easy access to all
Access on the top and sides requires the unit to slide out on slides. A lock in the slide latch
components
prevents inadvertent sliding when the rp8400 is being moved.
The rp8400 extends 31 inches, allowing 3.5 inches of space for access to the external rear PCI
cables, core I/O cables, and ac power cables. Once the chassis is extended on slides, access is
achieved by the removal of the top cover and side covers held on with captive hardware.
For safety, an interlock device allows only one device to be extended at a time. A front foot and
ballast system provide rack stability. (The rack ballast and front foot are required for safety.)
A large cable management arm, included with each rack-mounted server, facilitates cable
dressing when the rp8400 is extended from the rack.
front access
• bulk power supplies
• front system fans
• PCI dc-to-dc converters
• hard drives
• DVD/tape drives; these devices are connected with a service loop located inside the media
bay, allowing these devices to be serviced without the need for rear or side access
rear access
• rear system fans
• PCI card cables
• ac power cables
• core I/O modules and cables
right side access
• cell boards (These are located on the right side because the front door of the HP RBII rack
hinges on the left. This allows the cell boards to slide out some 16 inches for removal. To
shorten critical bus lengths, the cell boards are mounted upside down. To access RAM and
CPUs, lay the cell board on a work surface.)
• PCI backplane (also requires top cover to be removed)
• PCI board-mounted voltage regulator modules (VRMs) (also requires removal of the top cover
and structural access panel)
left side access
• system backplane (a hinged backplane secured by a single jack knob makes backplane
removal independent of the PCI FRU)
top access
• PCI cards
• PCI fan modules
• mass storage backplane (held in place by two captive screws)
