Figure 2. HP Router 650 Chassis
The chassis' first slot is occupied by the system's main processor, here called
the routing engine. It includes a console port and router resetting controls.
The other four slots may be filled with LAN or WAN interface card modules.
Most of these interface products have four network ports each. They can be
installed in any combination. The four ports on HP's Ethernet/IEEE 802.3
card product use "garages" to provide flexibility in media attachment. Each
garage accepts either a AUI, BNC, FOIRL (fiber-optic), or twisted-pair type
of recessed miniature adapter (transceiver) modules. The chassis also
contains a module of variable-speed fans and one auto-ranging power
supply. A second power supply can be added for load sharing and
redundancy.
All interface products (cards and transceivers), the redundant power supply,
and the fan module can be replaced on line without interrupting network
connections and components that are still operating (here called "hot
swap"), and replacements will be autodetected and autoconfigured.
The LEDs are moved out behind all the cabling into plain view. An LED PCA,
above the slots, provides multiple status indicators for each port on each
card, for overall chassis status, and for the fan and redundant power supply.
