Statement 1030

Required Tools

The following tools are required to perform the memory upgrade kit installation:

•Antistatic mat or foam pad to support and protect the removed supervisor engine

•3/16-inch flat-blade screwdriver for the captive installation screws on the supervisor engine

•Your own ESD-prevention equipment or the disposable grounding wrist strap included with all upgrade kits, field-replaceable units (FRUs), and spares

Caution Always use an ESD wrist strap when handling modules or coming into contact with internal components.

Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029

Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034

Removing the Supervisor Engine 720

To install the DRAM DIMM upgrade, you must first remove the Supervisor Engine 720 from the switch.

The Supervisor Engine 720 is a required system component. If only one Supervisor Engine 720 is present, removing it while the system is operating causes the system to halt. When two Supervisor Engine 720s are installed, hot swapping allows you to remove and replace one of the supervisor engines without turning off the system power.

To avoid erroneous failure messages, note the current configuration of all interfaces before you remove or replace another switching module, and allow at least 15 seconds for the system to reinitialize after a module has been removed or replaced.
