Installing and Removing Line Cards
•
Slot 11 and any other empty Cisco 6260 NI-2 DSLAM slot—Must contain a blank faceplate (refer
to the Cisco 6260 Hardware Installation and Troubleshooting Guide for details)
To install a line card in a Cisco 6260 chassis slot, perform the following steps:
Caution
Static voltages as low as 30 volts can cause latent damage to circuitry. Be sure to observe all
standard antistatic procedures (for example, wear a grounding strap).
Note
If an unexpected result occurs when you perform the following procedure refer to the
Cisco 6260 Hardware Installation and Troubleshooting Guide.
Warning
Blank faceplates and cover panels serve three important functions: 1) they prevent
exposure to hazardous voltages and currents inside the chassis; 2) they constrain
electromagnetic interference (EMI) that may otherwise disrupt other equipment;
and 3) they direct the flow of cooling air through the chassis. Do not operate the system
unless all line cards, blank faceplates, front covers, and rear covers are in place.
Step
Procedure
Step 1
Hold the line card vertically, with its faceplate toward you and its connector fingers facing the
DSLAM line card slot.
Step 2
Align the upper and lower edges of the line card with the upper and lower guides in the
DSLAM line card slot.
Step 3
Slide the line card into its DSLAM slot (Figure 1) by applying gentle pressure with both hands
at the top and bottom of its faceplate until its finger contacts enter the backplane connector.
Step 4
Rotate the faceplate locking tab on the line card to its unlocked position (see Figure 2) and
engage the locking lever at the upper front rail of the DSLAM chassis (see Figure 1).
Step 5
Press the locking lever down; this action inserts the line card finger contacts into the backplane
connector.
Step 6
Rotate the line card locking tab with a small screwdriver. When you insert the line card, the
green Status LED on the faceplate should light (firmware on the line card runs an internal test
to ensure proper line card operation). If the Status LED does not light, replace the line card.
Step 7
Install a blank faceplate to cover each empty slot in the Cisco 6260 DSLAM. Secure the
faceplate to the DSLAM chassis by rotating its locking tab to the locked position (see
Figure 2).
