Q.
Does the Cisco Catalyst 2940 Series replace any existing or legacy products?
A.
Yes. The Cisco Catalyst 2940 Series provides an excellent replacement for the legacy Cisco 1548M, 1548U, 1538M, and 1538U
switches and hubs. These products have reached end-of-sale status.
HARDWARE
Q.
Why is the Cisco Catalyst 2940 Series ideal for end-user environments, outside of the wiring closet?
A.
The Cisco Catalyst 2940 Series is ideal for end-user environments for the following reasons:
●
A small form factor allows it to fit unobtrusively in small areas.
●
Passive cooling without the use of a fan makes it completely silent, so it does not disrupt quiet environments.
●
A durable, all-metal shell protects the switch from accidental or intentional physical abuse.
●
A mounting kit is provided for wall-mounting, desk-mounting, or under-the-desk mounting. A specially designed magnet for
mounting to metal surfaces is also provided.
●
A separately purchased security cable (commonly used with laptops) can be installed in one of the security slots on each side of the
switch to prevent theft.
●
An optional cable guard protects the Ethernet cables from tampering or removal, providing further protection against theft.
Q.
Does the Cisco Catalyst 2940 Series support stacking?
A.
No. The Cisco Catalyst 2940 Series does not have a stacking interface and does not support the Cisco GigaStack
®
gigabit interface
converter (GBIC).
Q.
Do Cisco Catalyst 2940 Series Switches have redundant power supply (RPS) support?
A.
No. In order to minimize the cost and size of the Cisco Catalyst 2940 Series, there is no support for power supply redundancy
Q.
Can the 100-FX and 1000BASE-X Small Form-Factor Pluggables (SFPs) be used concurrently on the Cisco Catalyst 2940-
8TF?
A.
No. Only one uplink can be used at a time. If no SFP is inserted, the switch will use the 100-FX port for the uplink. If an SFP is
inserted, the switch will use the 1000BASE-X uplink.
Q.
What SFPs are supported on the Cisco Catalyst 2940 Series?
A.
Cisco Catalyst 2940 Series Switches support Cisco 1000BASE-LX/LH, 1000BASE-SX 1000BASE-T, 1000BASE-ZX, and CWDM
SFPs.
Q.
Do Cisco Catalyst 2940 Series Switches interoperate with SFPs from other vendors?
A.
No. Like other Cisco switches and routers, Cisco Catalyst 2940 Series Switches do not interoperate with other vendors’ SFPs.
Q.
What type of fiber connectors are supported on the Cisco Catalyst 2940-8TF Switch?
A.
The Cisco Catalyst 2940-8TF supports an MT-RJ connector for the 100BASE-FX port, and an LC connector for the SFP port. For
customers that use SC or ST connectors, MT-RJ-to-SC and MT-RJ-to-ST fiber patch cables and LC-to-SC fiber patch cables are
available from Cisco.
SECURITY
Q.
How can I manage the usernames and passwords for switches?
A.
Rather than configuring the usernames and passwords of network administrators on every switch, the Cisco Catalyst 2940 Series
supports both RADIUS and TACACS+ authentication servers. Every time network administrators attempt to configure or monitor a
switch, they will be prompted to enter their username and password. In large networks, it is more efficient to store the username and
password information on a centralized RADIUS or TACACS+ server, instead of on every switch. In addition, different network
