Page 15: Installing Optional Hardware Modules
2.3.2 Removing a GBIC Caution: GBIC 1000T modules run hot under normal operating conditions. When it has been removed from the system, place it on a heat resistant surface and allow the module to cool before handling. Note: Unnecessary removals/insertions of a GBIC module will lead to premature failure of the GBIC. The rated duty cycle for a GBIC module is 100 to 500 removals/insertions. -

Page 20: Using The Stacking Feature
2.11 Using the Stacking Feature (IC3524 only) The IC3524 firmware v.1.1 (or later) offers a stacking feature that allows the user to stack up to eight units, all sharing one IP address of the master switch (unit #1). This is an efficient and cost-effective way to add ports as needed. - Page 21 For stacking operation, the stacking feature must first be enabled on each unit (by default, stacking is disabled). Establish a console connection to the first unit. Type k in the Configuration Menu to access the Stack Management menu. Type t to toggle the switch from “disabled” to “enabled”. Repeat for all remaining units.

Chapter 6. SNMP Management The switch can be managed using a Simple Network Management Protocol (SNMP) compatible management station running platforms such as HP OpenView or MG Soft’s MIB Browser. 6.1 SNMP Management Operations A network management application is concerned with performance statistics gathered by the devices on the managed network, in reading and changing current configuration information, and in receiving alerts of unusual events. -

6.3 Community Name and Security SNMP v.1 was not designed to be a secure protocol. There is no true password, although the string known as a community string does serve some of the same purposes. SNMP-aware devices, such as this switch, often ship with well-known community strings. For this reason, it is important that you change the default community strings before putting the switch on a network. - Page 72 • The IP group -- This group contains counters for Internet Protocol Traffic.

Page 73: Chapter 7. Switching Concepts
Chapter 7. Switching Concepts A bridge is a hardware device used to connect multiple networks into one big network. However, when a bridge receives a broadcast from one interface, it will forward the frame to all interfaces and flood the wire, easily overwhelming the network. -
Page 74: Port Vlan Id
7.1.3 Port VLAN ID To allow untagged packets to participate in a VLAN, a Port VLAN ID (PVID) must be assigned in the relevant port(s). Each port on the switch has a default PVID of 1 (the default VLAN) and will receive both tagged and untagged frames. -
Page 75: Forward Delay
Forward Delay After a recalculation of the spanning tree, the Forward Delay parameter regulates the delay before each port begins transmitting traffic. If a port begins forwarding traffic too soon (before a new root bridge has been selected), the network can be adversely affected. The default value for Forward Delay is 15 seconds. Note: The above parameters (Hello Time, Maximum Age and Forward Delay) are constrained by the following formula: (Hello Time + 1) <= Maximum Age <= 2 x (Forward Delay –... -
Page 76: Flow Control
7.3.2 Flow Control With a link operating at a high data rate, a switch may experience occasional limitations in the buffer space used to store Ethernet frames before forwarding them. In this situation, if the sending station continues to send frames, the switch will have no option but to discard the frames. This may quickly lead to unacceptable delays in upper-level protocols. -
