This chapter provides information on the Cisco 1500 series micro hub desktop hubs. The information is organized into the following sections:
The Cisco 1500 series micro hubs are small, desktop hubs that can be used to connect network devices in a small branch or remote office environment. You can connect up to eight network devices to one Cisco 1500 series micro hub. Up to five hubs can be stacked and interconnected.
The Cisco 1500 series models include the Cisco Micro Hub 1501, the Cisco Micro Hub 1502, and the Cisco Micro Hub 1503.
- Cisco Micro Hub 1501--An 8-port hub that does not have a console port and cannot be monitored or controlled, even when connected to a Cisco Micro Hub 1503. This model can also be used alone if no management capabilities are required.
- Cisco Micro Hub 1502--An 8-port hub that does not have a console port, but can be monitored and controlled by connecting it to a Cisco Micro Hub 1503.
- Cisco Micro Hub 1503--An 8-port hub that can be monitored and controlled through the console port on the rear panel, using the hub's own firmware, or remotely using optional network management software (such as Cisco Works for Windows).
You can use any of the hub models as a standalone networking device, or connected to other compatible 10BaseT hubs or switches to form a larger network. You can also stack and connect up to five hubs through rear-panel ports, to form a larger network.
By adding one Cisco Micro Hub 1503 to a stack of Cisco Micro Hub 1502s, you can configure and manage all the hubs in the stack from a remote location. Stacking five Cisco micro hubs together allows you to manage up to 40 hub ports.
Figure 125 shows a rear view of a Cisco 1500 series micro hub, and shows the rear view of a stack of Cisco 1500 series micro hubs.
Note The Cisco Micro Hub 1501 does not have an in, out, or console port. The Cisco Micro Hub 1502 does not have a console port.
