Cabling Requirements The cabling for connections to the NetStacker II hubs must meet or exceed the following standards: 10Base-T 10Base-T transmission connection requires UTP (Unshielded Twisted Pair) Category 3 cables, not to exceed 100 meters in length.
SHBBook Page 5 Wednesday, March 3, 1999 8:03 PM Placement and Mounting This section describes how to mount the NetStacker II on a desktop or shelf. Hub Location The location chosen for the NetStacker II hub should be less than 100 meters from servers, workstations, and other devices.
Ensure that the ventilation holes do not get blocked. Figure 2-6 Rack mounting Connecting Network Devices The Auto-sensing capability of the NetStacker II hub allows you to connect 10Mbps and/or 100Mbps devices. Connecting Workstations or Servers To connect your hub to workstations, servers, or other nodes:...
10Mbps Figure 2-8 Connecting network devices Connecting to Another Hub To connect the NetStacker II hub to a switching hub or a repeater hub, take the following steps. Choose the appropriate cable depending on which port you want to connect to on the NetStacker II hub. See Table 2-1 to determine which cable and uplink button setting you need to use.

This reduces considerably the expense of equipping each hub for management. It is not necessary to configure a Hub ID for each NetStacker II hub in a stack. The auto-configure feature takes care of this for you. Check the 50-pin “stacking” cable that was included in the package with your NetStacker II hub.

SHBBook Page 12 Wednesday, March 3, 1999 8:03 PM Installation Powering on the Hub The NetStacker II hub may be turned on with (or without) LAN segment cables connected. To power on the hub: Connect one end of the power cord (supplied) into the AC power connector on the back panel of the hub.
SHBBook Page 1 Wednesday, March 3, 1999 8:03 PM This chapter explains how to interpret the front panel LED indicators on NetStacker II dual speed hubs. There are no LEDs on the rear panel. The LEDs are used to facilitate monitoring and troubleshooting. These LEDs...
Figure 3-2 Power LED The Power LED is green and should always be lit when the NetStacker II is in use. After power is turned on, the LED indicators should respond as follows: All LED indicators blink momentarily. This represents a system reset.
If your hub is not part of a stack, the LED for ID number 1 will be lit. If no Hub ID LED is lit on your NetStacker II hub, or if more than one hub in a stack has the same ID number lit, there is a problem with the system. Check with Asanté...
