Remove/Install a Line CardPage 1 of 4
VoiceMemo Release 6.OA and later
This procedure describes first how to remove and then how to install a line card in a
Centigram Series 6 Model 70.
WARNING!This procedure requires that you shut down the system, which results
in an interruption to call processing on the server.Centigram
recommends that you perform these steps during periods of low
tKl.flk.
DANGER!Disconnect the server from its power source before connecting either
cables or comnonents.
CAUTION!Protect your server from ESD damage 
during handling of allcomnonents.
Note:You can find TRs referenced in this procedure in the Centigram Series 6
Step
Technical Reference Manual.
Reference
@II Observe Precautions
1.Put on a grounded wrist strap and attach the other end to the cabinet. Doing so
protects the component from electrostatic discharge.
2.Shut down the system and turn off the power, if you have not already done so.
CAUTION!Removing a component while the power is on can severely damage
the component you are working on and other peripherals.
3.Wait one minute after you turn off the power before you remove any components.
The hard disk should stop spinning and be quiet.
4.When removing a component, place it on a nonconductive surface, such as an anti-
static bag. Make sure you have the anti-static bags before you begin.
5.Put identification tags on all cables and disconnect cables from the server.

@ED Remove the line Card
6.Remove the cover to the server.
7.Identify the line card you want to remove.Disconnect all cables from the board
you are going to remove.
8.Looking at the line cards from the front of the cabinet, locate the screws that secure
the cards in the mother board along the back panel.Remove the screw that holds
the line card retaining bracket to the cabinet, as shown in Figure 1.
8
9.Holding the card at each end, carefully pull the card straight out until the edge
connectors are free. Be careful not to scrape the card against other components.
CAUTION!If removing a line card and not replacing it, install a slot cover
over the vacant guide slot in the server back panel.
a.Place the lower end of the cover so that the metal tab fits
outside, hooking over the cabinet edge. Let the cover lean
inward; do not push in or down yet.
b.Pull the slot cover up far enough to hook the prong over
the guide and bring it flush with the cabinet wall.
Pushdown to secure the slot cover in place. The slot opening
must be covered to maintain the electromagnetic
emissions characteristics of the server and ensure proper
cooling inside. See Figure 2 for details.
If you are not replacing the removed line card, also remove the
cables associated with it.10. Place the line card in an anti-static protective wrapper and prepare it for return and
repair.
