Hardware Overview
At the heart of the Passport 2430 hardware architecture is a high-performance, 50 MHz
Motorola MPC860T microprocessor, which ensures high forwarding and filtering rates
across each of the Passport 2430’s network interfaces. The base unit offers a single
10/100 LAN interface, and two WAN adapter module slots. The Passport 2430 also
supports two PCMCIA slots – one for flash memory and one for a console modem,
further increasing the unit’s flexibility. With no fan, the Passport 2430 is quiet enough to
be used on a desktop.

DRAM Memory. The Passport 2430 comes standard with 16 megabytes (MB) DRAM
configuration, but can easily be upgraded to 32MB. Customization of the DRAM,
between local and global memory usage, is supported. Router software resides in local
memory, while global memory is dedicated to packet buffers. Through these reserved
buffers, the Passport 2430 prevents traffic overflow — and resulting network delays —
caused by large bursts of traffic (file transfer operations, for example).

PCMCIA Flash Memory Card. A 16 MB externally accessible PCMCIA Flash memory
card allows for nonvolatile storage of router software and configuration files. Router
upgrade and fault recovery procedures are quick and simple since software image and
configuration files can be remotely downloaded to the Flash card. Additionally, the Flash
card can be programmed at a network center, mailed to the remote site, and easily
installed by on-site personnel. To provide redundancy, the PCMCIA Flash can be
logically divided into two partitions of equal size. Each partition is a uniquely
addressable and fully functional Flash file system volume where copies of boot images
and configuration files can be stored.

Modem Support. The Passport 2430 supports both a V.34 console modem option, and a
V.90 PCMCIA Type III modem for greater flexibility. These options simplify remote
router deployment, and enable out-of-band troubleshooting, should network access be
unavailable. The V.34 modem is available as a WAN adapter module, while the
PCMCIA Type III card fits into one of the Passport 2430’s two PCMCIA slots. The V.90
PCMCIA can be used for dialing into the Passport 2430 for out-of-band management.

LED Matrix Display. A matrix of LEDs present clear, at-a-glance status of key Passport
2430 system components including: Power, Boot, Run, Fail, Ethernet Transmit, Ethernet
Receive, Ethernet Link. (see Figure 3). Networking administrators can obtain a remote
view of the router’s status via SNMP and Nortel Networks’ Optivity management and
surveillance tools.
