Upgrading the Memory
Upgrading the Memory
This section describes how upgrade the switch processor (SP) and the route processor (RP) memory in
the chassis. Both models of the ME
6524 Ethernet switch chassis ship with 256 MB DRAM (SP
memory) and 512
MB DRAM (RP memory) as the default. You can upgrade both the SP and the RP
memory with the following kits:
• SP memory upgrade kits
–
MEM-XCEF720-512= (Upgrades the SP memory from 256 MB to 512 MB)
–
MEM-XCEF-1GB= (Upgrades the SP memory from 256 MB to 1 GB)
• RP memory upgrade kits
–
MEM-MSFC3-1GB= (Upgrades the RP memory from 512 MB to 1 GB)
Note In order to remove the cover from the chassis, you must first remove both power supplies from the
chassis.
To upgrade the SP and the RP memory on the Cisco ME 6524 Ethernet switch, follow these steps:
Step 1 If your chassis is equipped with one or two DC-input power supplies, remove them from the chassis.
Refer to the
“Removing and Installing the DC-Input Power Supply” section on page 4-1 for the
procedure.
Step 2 If your chassis is equipped with one or two AC-input power supplies, remove them from the chassis.
Refer to
“Removing the AC-Input Power Supply” section on page 4-7 for the procedure.
Step 3 Remove the fourteen screws that secure the top cover to the chassis. Remove the top cover and set it and
the fourteen screws aside.
Step 4 Attach an ESD grounding strap to your wrist and to ground.
If you are unsure about the correct way to attach an ESD grounding strap, refer to the “Preventing
Electrostatic Discharge Damage” section on page 2-7
Step 5 Locate the SP DRAM DIMM in its socket on the main board. (See Figure 4-5 for the locations of the SP
and the RP DRAM DIMMs.)
