Overview
Overview
The rear panel of the Catalyst 2955 switch has a DIN rail mounting clip assembly, as shown in Figure 1.
Figure 1 DIN Rail Clip Parallel Mounting Configuration
Mounting the Switch on a DIN Rail
You can mount the Catalyst 2955 switch on a DIN rail in a parallel or a face-down configuration.
The switch ships with the DIN rail clip assembly installed on the rear panel, for a parallel mounting
configuration. To mount the switch in a face-down configuration, unscrew the four DIN rail clip
mounting screws from the rear panel, and then reuse the screws to install the clip on the top of the switch,
as shown in Figure 2.

Warning This equipment is supplied as “open type” equipment. It must be mounted within an enclosure that is
suitably designed for those specific environmental conditions that will be present and appropriately
designed to prevent personal injury resulting from accessibility to live parts. The interior of the
enclosure must be accessible only by the use of a tool.
The enclosure must meet IP 54 or NEMA type 4 minimum enclosure rating standards.
Caution To prevent the switch from overheating, there must be a minimum of 3 inches between any other device
and the top, bottom, or sides of the switch.

Obtaining Technical Assistance
Cisco TAC inquiries are categorized according to the urgency of the issue:
•Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities,
product installation, or basic product configuration.
•Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably
impaired, but most business operations continue.
•Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects
of business operations. No workaround is available.
•Priority level 1 (P1)—Your production network is down, and a critical impact to business operations
will occur if service is not restored quickly. No workaround is available.
The Cisco TAC resource that you choose is based on the priority of the problem and the conditions of
service contracts, when applicable.
Cisco TAC Web Site
You can use the Cisco TAC Web Site to resolve P3 and P4 issues yourself, saving both cost and time.
The site provides around-the-clock access to online tools, knowledge bases, and software. To access the
Cisco TAC Web Site, go to this URL:
http://www.cisco.com/tac
All customers, partners, and resellers who have a valid Cisco service contract have complete access to
the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a
Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or
password, go to this URL to register:
http://www.cisco.com/register/
If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco
TAC Web Site, you can open a case online by using the TAC Case Open tool at this URL:
http://www.cisco.com/tac/caseopen
If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC
Web Site.
Cisco TAC Escalation Center
The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These
classifications are assigned when severe network degradation significantly impacts business operations.
When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer
automatically opens a case.
To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to this URL:
http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml
Before calling, please check with your network operations center to determine the level of Cisco support
services to which your company is entitled: for example, SMARTnet, SMARTnet Onsite, or Network
Supported Accounts (NSA). When you call the center, please have available your service agreement
number and your product serial number.
