Chapter 1      Catalyst 6500 Series Switch Chassis Overview
  Catalyst 6503-E
  • Supervisor Engine 32, Supervisor Engine 32 PISA, and the Supervisor Engine 720 require 
additional cooling. You must install the optional high-speed fan tray (FAN-MOD-3HS) in the 
chassis when any of these three supervisor engines are installed.
  • The uplink ports are fully functional on the redundant supervisor engine when it is in standby mode. 
Note In systems with redundant supervisor engines, both supervisor engines must be the same model 
and have the same daughter card configurations. Each supervisor engine must have the resources 
to run the switch on its own, which means that all supervisor engine resources are duplicated. 
Identical supervisor engine memory configurations are recommended but are not required as 
long as the supervisor engine with the smaller memory configuration is sufficient to run the 
configured features of the switch. Additionally, each supervisor engine must have its own flash 
device and console port connections.

Catalyst 6503-E
The Catalyst 6503-E switch is an enhanced version of the Catalyst 6503 switch. The 3-slot (numbered 
from (1) top to (3) bottom), 4
 RU, horizontal chassis supports redundant power supplies and redundant 
supervisor engines. It also supports a greater power capacity per slot than the Catalyst
 6503 switch 
chassis and supports the WS-X67xx and WS-X68xx switching modules. The Catalyst
 6503-E switch 
chassis is NEBS L3 compliant. Supervisor engine support and restrictions for the Catalyst
 6503-E 
includes:
  • Supervisor Engine 2, Supervisor Engine 32, Supervisor Engine 32 PISA, Supervisor Engine 720, 
Supervisor Engine
 720-10GE, and Supervisor Engine 2T are supported. 
Note Refer to your software release notes for specific information on the minimum software release 
versions required to support the supervisor engines in the Catalyst
 6503-E chassis.
  • Supervisor engines must be installed in slot 1 or slot 2.
Note Slots not occupied by supervisor engines can be used for modules. Check your software release 
notes for any restrictions on the type of module that can be installed.
  • Supervisor Engine 720, Supervisor Engine 720-10GE, and Supervisor Engine 2T have a built-in 
switching fabric. The Switch Fabric Modules (WS-C6500-SFM and WS-X6500-SFM2) are not 
supported by Supervisor Engine
 720 and Supervisor Engine 720-10GE and cannot be installed in 
the same chassis.
