Note: The network installation must meet the requirements described in this chapter to

ensure satisfactory performance of this equipment. Failure to do so will produce poor

network performance.

Note: The SecureStack A2 Configuration Guide and the Cabling Guide referred to in the

following sections can be found on the Enterasys Networks World Wide Web site:

http://www.enterasys.com/support/manuals

For details about obtaining the manuals, refer to “Related Documents” on page xvi.

Note: If an RJ45 port is to operate at 100 Mbps, Category 5 cabling must be used.

Category 3 cabling does not meet the 100 Mbps specifications. Refer to 100BASE-TX

Network (page 2-2) for information about 100BASE-TX networks and cabling.

Note: When using the RJ45 ports on the SecureStack A2 for 100 Mbps operation use

Category 5 UTP cabling with an impedance between 85 and 111 ohms.

The fixed SecureStack A2 ports are capable of operating at 10 and 100 Mbps. This is

accomplished by the SecureStack A2 when Auto-Negotiation is enabled. This enables the

SecureStack A2 to automatically sense the transmission speed of the other device and

adjust for the speed accordingly.

Important

The following procedures assume that all switches have a clean configuration from manufacturing.

When adding a new switch to an already running stack, it is also assumed that the new switch is

using the same firmware image version as other switches in the stack.

Note: Once switch IDs are assigned, they are persistent and will be retained during a

power cycle to any or all of the switches.

Adding a New Switch to an Existing Stack

Usethefollowingproceduretoinstallanewswitchtoanexistingstackconfiguration.

Thisprocedureassumesthatthenewswitchbeingaddedhasacleanconfigurationfrom

–Iftherunningstackusesadaisychaintopology,makethestackcableconnections

fromthebottomofthestacktothenewswitch(thatis,STACKDOWNportfrom

stackcableconnectionstothenewswitchtoclosetheloop.

3. Applypowertothenewswitch.

Important Considerations About Using Clear Config in a Stack

When using the clear config command (as described in the SecureStack A2 Configuration Guide)

to clear configuration parameters in a stack, it is important to remember the following:

• Use clear config to clear config parameters without clearing stack switch IDs. This command

WILL NOT clear stack parameters and avoids the process of re-numbering the stack.

• Use clear config all when it is necessary to clear all config parameters, including stack switch

IDs and switch priority values.

Caution: To prevent damaging the switch, ONLY connect a Power over

Ethernet-compliant Redundant Power System (C2RPS-POE) to the redundant power

supply connector. The switch is only compatible with the SecureStack C2RPS-POE

redundant power supply system.

Precaución: Conecte una fuente de poder redundante (RPS) SecureStack PoE (C2RPS-

POE) al cable de corriente. De lo contrario, el dispositivo puede dañarse.

Note: When switches are connected in a stack configuration and all stacking cables are

connected before powering up the switches, one switch in the stack will be automatically

designated as the Manager of the stack and its Console port will remain active. All other

switches will become Member switches and their Console ports will be deactivated.
