Cabletron Systems SmartSwitch Hot Swapping a Secondary Control Module, Installing a New Line Card

Chapter 2: Hot Swapping Line Cards and Control Modules

Warning: Do not remove the line card unless the Offline LED is lit. Doing so can cause the SSR to crash.

2.Loosen the captive screws on each side of the line card.

3.Carefully remove the line card from its slot in the SSR chassis.

Installing a New Line Card

To install a new line card:

1.Slide the line card all the way into the slot, firmly but gently pressing the line card fully in place to ensure that the pins on the back of the line card are completely seated in the backplane.

Note: Make sure the circuit card (and not the metal plate) is between the card guides. Check both the upper and lower tracks.

2.Tighten the captive screws on each side of the line card to secure it to the chassis.

Once the line card is installed, the SSR recognizes and activates it. The Online LED button lights.

Hot Swapping One Type of Line Card With Another

You can hot swap one type of line card with another type. For example, you can replace a 10/100Base-TX line card with a 1000Base-SX line card. The SSR can be configured to accommodate whichever line card is installed in the slot. When one line card is installed, configuration statements for that line card are used; when you remove the line card from the slot and replace it with a different type, configuration statements for the new line card take effect.

To set this up, you include configuration statements for both line cards in the SSR configuration file. The SSR determines which line card is installed in the slot and uses the appropriate configuration statements.

For example, you may have an SSR with a 10/100Base-TX line card in slot 7 and want to hot swap it with a 1000Base-SX line card. If you include statements for both line cards in the SSR configuration file, the statements for the 1000Base-SX take effect immediately after you install it in slot 7.

Hot Swapping a Secondary Control Module

If you have a secondary control module installed on the SSR, you can hot swap it with another Control Module or line card.
