Supported Control Devices

NETLAB_AE control devices provide internal connectivity, console access, and managed power. Control devices are dynamically managed by NETLAB_AE and are not accessible or configurable by end users.

Control Switches

NETLAB_AE uses a control switch to provide connectivity between the NETLAB_AE server, access servers, remote PCs, and switched outlet devices. Control switches are not accessed by lab users.

The following table lists the Cisco switch models supported by NETLAB_AE for use as a control switch.

Cisco Switch Model	Required Image
Catalyst 1912 Enterprise Edition1	9.00.04 Enterprise Edition (or later)
Catalyst 1924 Enterprise Edition1	9.00.04 Enterprise Edition (or later)
Catalyst 2950-12	12.1(22)EA2
Catalyst 2950-24	12.1(22)EA2
Catalyst 2950-48	12.1(22)EA2
Catalyst 2960-24	12.2.25
Catalyst 2960-48	12.2.25
Catalyst 3550-12	12.1(22)EA2
Catalyst 3550-24	12.1(22)EA2
Catalyst 3550-48	12.1(22)EA2

¹ End-of-life, not recommended. Functionality may be limited. Not compatible with virtual PC pods.

Access servers

Access servers provide console connections to lab equipment. Using this approach, users can access lab gear even when no configurations have been loaded in the lab devices. NETLAB_AE proxies all connections through the access server. This special proxy allows simultaneous sharing of console ports and allows all users to access the lab environment using a single IP address and single Telnet port.

The following table lists the Cisco devices supported by NETLAB_AE for use as an access server.

Cisco Model	Ports Provided	Required Image
NM-32A Module in Cisco Router (2811, 2610/11/20/21)	32	12.0(5)T or later
NM-16A Module in Cisco Router (2811, 2610/11/20/21)	16	12.0(5)T or later
2511-RJ	16	12.0(5)T or later
2511 (octal cables)	16	12.0(5)T or later
2509-RJ	8	12.0(5)T or later
2509 (octal cables)	8	12.0(5)T or later

Switched Outlet Devices

Switched outlets provide managed electrical power, allowing NETLAB_AE and users to turn lab equipment on and off. The power of each managed device in a NETLAB_AE equipment pod is connected to an American Power Conversion (APC) Switched Rack PDU. This provides three functions:

• Reboot devices during NETLAB_AE automated operations.
• Allow users to control power of a lab device (making password recovery possible).
• Power off devices when not in use to reduce energy and cooling requirements.

Each APC Switched Rack PDU provides eight (8) managed outlets. The following table lists the Switched Outlet devices supported by NETLAB_AE.

Switched Outlet Device	Outlets	Voltage	Outlet Type
APC 7900 Switched Rack PDU	8	120V	NEMA 5-15R
APC 7920 Switched Rack PDU	8	208V	IEC 320 C13
APC 9211 Master Switch (end of sales)	8	120V	NEMA 5-15R
APC 9212 Master Switch (end of sales)	8	208V	IEC 320 C13

The AP7920 and AP9212 are for countries with 200-240 VAC power. Eight (8) IEC-320 C13 outlets are provided. This will require (8) C13 to C14 power cords such as the AP9870 (sold separately). One (1) IEC-320 C14 inlet is provided on the input side. The C14 connector is the same used on a Cisco router or switch.
