Removing and Replacing a SPA Interface Processor
Caution Always handle the SIP by the carrier edges and its handle; never touch the SIP components or connector
pins.
Figure 8-15 Handling the Cisco ASR 1000 Series SPA Interface Processor
Although the metal carrier helps to protect the SIP and SPA from ESD, wear a preventive antistatic strap
whenever handling the SIP and SPA. Ensure that the strap makes good skin contact and connect the
strap’s clip to an unpainted chassis surface to safely channel unwanted ESD voltages to ground.
If no wrist strap is available, ground yourself by touching the metal part of the chassis.
Following are guidelines for preventing ESD damage:
• Always use an ESD wrist strap or ankle strap when installing or replacing the Cisco ASR 1000
Series SPA Interface (SIP) and shared port adapter. Ensure that the ESD strap makes contact with
your skin.
• Handle the Cisco ASR 1000 Series SPA Interface (SIP) or shared port adapter by its metal carrier
edges and handles; avoid touching the printed circuit board or any connector pins.
• When removing an Cisco ASR 1000 Series SPA Interface (SIP) or shared port adapter, place it on
an antistatic surface with the printed circuit board components facing upward, or in a static shielding
bag. If you are returning a shared port adapter or Cisco ASR 1000 Series SPA Interface (SIP) to the
factory, immediately place it in a static shielding bag.
