The Cisco 2500 series hub is available with 8, 14, or 16 hub ports supporting Ethernet interfaces. A single BRI port is supported with 14 hub ports. The hub system code operates from Flash memory by default. For more information on system-code operation, see the section "System Operation Prerequisites" in the chapter "Preparing for Installation."
The Cisco 2500 series access server contains one or two asynchronous 68-pin SCSI-type connectors, depending on the access server model. Using a modular SCSI-type breakout cable (available from Cisco Systems), you can connect to 8 asynchronous serial devices. The modular SCSI-type breakout cable contains one 68-pin connector on one side of the cable and eight DB-25 connectors or RJ-45 connectors on the other side of the cable (depending on the type of cable you ordered). Therefore, if the Cisco access server contains one asynchronous 68-pin SCSI-type connector, using the modular SCSI-type breakout cable you can connect to eight asynchronous serial devices. If the Cisco access server contains two asynchronous 68-pin connectors, you can connect to 16 asynchronous serial devices.
The access server interface types include Ethernet 802.3 (AUI), Token Ring 802.5 (DB-9), asynchronous serial, and synchronous serial. The chassis can be rack or wall-mounted, or it can be placed on a table or desktop.
