Removing the Air Intake Grill and Assembly
Before you can access the two bay controller modules you must first remove the front grille and front air intake assembly.
PROCEDURE: Use the following steps to remove the air intake grill and assembly:
Step 1 Remove the front grille by turning four winged screws 1/4 turn counterclockwise. Refer to Figure 1.
Figure 1. Front Grill Removal
Step 2 Remove the front air intake plenum assembly. The front air plenum assembly attaches at the top center with two Phillips screws and pivots down on two tabs at the bottom. Use a #2 Phillips screwdriver to remove the screws, see Figure 2. Tilt the plenum outward from the top and lift up to remove the lower tabs from the lower bracket.
Figure 2. Removing Front Air Plenum Assembly
Step 3 Grasp the faceplate handle with one hand and carefully pull the cooling module toward the front of the bay (a few inches) to disengage, refer to Figure 6.
Installing the Bay Controllers
The bay controller modules are shipped separately and need to be installed. To avoid damage to the backplane, a detailed inspection of the bay controller module VDHM connector is required each time a module is removed or inserted.
PROCEDURE: Use the following steps to install the bay controller:
CAUTION (2) Risk of service interruption or equipment damage. Risk of electrostatic damage. When handling circuit cards, wear a grounded antistatic wrist strap or equivalent protection to avoid damaging electrostatic parts.
Step 1 Remove the bay controller module from its packaging and static protection bag.
Step 2 Before inserting the bay controller module, remove the VHDM protective cap from the end of the module before use. Set the protective cap aside in a safe place. Refer to Figure 3.
Figure 3. Remove VHDM Protective Cap Before Use
(router module depicted)
- A detailed inspection of the VHDM connector on the back of the bay controller module is required prior to insertion. Lay the module gently on a flat surface so you can perform a VHDM connector inspection.

.
NOTE If the VHDM connector has any signs of damage, DO NOT insert it into a bay. Mark the module as damaged and call TSR-BY-AVICI to request an RMA.
Step 4 Look into bay controller slot to ensure bay controller path is free of obstruction; for example, packing materials.
Step 5 Continue installation process. Open the release latches on the bay controller module.
Step 6 Align the bay controller module with the nylon rails above the baseplate.
Step 7 Slide the bay controller modules into the left or right card guides from the front of the bay. Refer to Figure 6.
Figure 6. Reinstalling the Bay Controllers
Step 8 Engage the latches to seat the connector at the rear of the module firmly in the controller backplane.
Repeat Step 5 through Step 8 for the remaining bay controller.
Removing the Bay Controller
To access and replace the TSR II bay controller module, it is necessary to remove the front air intake grille. It is not necessary to remove the cooling module.
To avoid damage to the backplane, a detailed inspection of the bay controller module VDHM connector is required each time a module is removed or inserted.
PROCEDURE: Use the following procedure to remove the TSR II bay controllers
Step 1 Remove the front grille per procedure above.
Step 2 Pull open the latches to release the latches on the bay controller module and to disengage the module from the backplane and bay frame.
Step 3 Pull the bay controller out through the bottom-front of the bay.
Step 4 Repeat steps 1 and 2 for the remaining module. Refer to Figure 7.
Figure 7. Removing Bay Controller
Step 5 Fully remove module and set on a flat surface to inspect the module's VHDM connector. A detailed inspection of the VDHM connector is required each time a module is removed or inserted.
Step 6 Carefully inspect the VHDM connector for damage such as deformed sockets, holes between socket columns, and deformed guide fins on top and bottom of the socket columns

.
NOTE If the VHDM connector has any signs of damage, DO NOT insert it into a bay. Mark the module and slot as damaged and call TSR-BY-AVICI (1-877-292-8424) to request an RMA.
Reinstalling the Front Air Plenum Assembly and Grille
PROCEDURE: Use the following procedure to install the front grill and air plenum assembly:
Step 1 Lay the front air plenum assembly in a horizontal position with the two tabs facing the receiving slots in the bottom of the TSR II chassis.
Step 2 Engage the tabs and swing the front air plenum assembly up until it contacts the TSR II chassis
Step 3 Secure air plenum assembly at the top with two Phillips head screws.
Step 4 Secure the front grille with four winged 1/4 turn screws.Turn clockwise to secure. Refer to Figure 9 and Figure 10.
