Preface
The following ATTENTION statements appear in this publication
and describe practices that must be observed while installing or
servicing the switch. An ATTENTION statement provides essential
information or instructions for which disregard or noncompliance
may result in equipment damage or loss of data.
ATTENTION ! Prior to servicing a product, determine the Ethernet LAN
configuration. Installation of products on a public customer intranet can
complicate problem determination and fault isolation.
ATTENTION ! A reset should only be performed if a CTP card failure is
indicated. Do not reset a managed product unless directed to do so by a
procedural step or the next level of support.
General Precautions When installing or servicing the product, follow these practices:
• Always use correct tools.
• Always use correct replacement parts.
• Keep all paperwork up to date, complete, and accurate.
ESD Precautions Follow these electrostatic discharge (ESD) procedures:
• If the product is connected to facility power (grounded), wear an
ESD wrist strap and grounding cable connected to the product
chassis.
• If the product is not connected to facility power (not grounded),
wear an ESD wrist strap and grounding cable connected to an
approved bench grounding point.
• Touch the product chassis once before performing a procedure,
and once each minute during the procedure.
