I/O Chassis for HP rp7410 and rp8400 Servers

HP rp7410 and rp8400 servers have two I/O chassis, each with 8 slots

numbered left to right from 1 to 8.

Both HP rp7410 and rp8400 server cabinets have a single I/O bay on the

cabinet’s rear that houses the two I/O chassis or “I/O domains”. When

you face the I/O bay, viewing the rear of the cabinet, the chassis on the

left is I/O chassis 0, and right is I/O chassis 1.

Cell 0 connects to chassis 0 and cell 1 connects to chassis 1.

In HP rp7410 servers, two PCI card slots are reserved for use by a

SCSI/LAN card: chassis 0, slot 1 and chassis 1, slot 8. This is a 64-bit

card that operates at 66 MHz and 3.3-volt signaling.

HP rp7410 and rp8400 I/O chassis card slot details are listed in

Table 1-2.

All slots in HP rp7410 and rp8400 I/O chassis can operate as 64-bit slots

and can accept 66 MHz PCI cards.

HP rp7410 and rp8400 I/O chassis slots 1–6 accept cards physically

keyed as 3.3-volt cards or keyed as universal cards. These slots can

operate at 66 MHz or 33 MHz with 3.3-volt signaling only.

Slots 7 and 8 in rp7410 and rp8400 I/O chassis accept cards keyed as

5-volt cards or keyed as universal cards. These slots normally operate at

33 MHz with 5-volt signaling, but when a 66 MHz capable card is

detected they are switched by software to operate at 66 MHz with

3.3-volt signaling.
